Your scraper ran perfectly for two weeks. Then it started failing. Block rates climbed from 3% to 47% overnight. You rotated IPs, changed headers, adjusted request timing. Nothing worked. You spent four hours debugging before realising the problem was not your code at all. It was the proxy API underneath it.
Proxy APIs are not interchangeable. The provider you use determines your success rate, your block rate, your cost per successful request, and whether your data pipeline runs without you babysitting it at midnight.
In 2026, anti-bot systems from Cloudflare, Akamai, DataDome, and PerimeterX have gotten smart enough to distinguish between residential IPs from ethically sourced networks and everything else.
Datacenter IPs now fail at 50 to 70% rates on protected targets. The quality of the peer network behind your proxy API determines everything.
This guide covers the 7 best proxy API providers in 2026. Every provider on this list has been tested against real targets. The rankings reflect actual performance data, not marketing claims.
Quick Tip: The cheapest proxy API per GB is rarely the cheapest per successful request. A provider at $2/GB with a 70% success rate costs more per clean data point than one at $5/GB with a 99% success rate. Always calculate cost per successful request, not cost per GB, before choosing your proxy API.

Cons
- Scraping API features cost extra on top of the base residential proxy plan, unlike all-in-one competitors
- 30-minute sticky session limit breaks workflows that need longer account sessions
- IP density per region is lower than Bright Data in smaller LATAM and MENA markets
Why Decodo for Proxy API Decodo is the right call when you need serious residential proxy API performance without committing to enterprise pricing. The 0.54-second response time and $2.20/GB pricing make it the highest value proxy API for scraping teams that have outgrown budget providers but do not need Oxylabs-level compliance documentation.
2. Oxylabs
Oxylabs operates 102 million residential IPs across 195 countries at a documented 99.99% uptime and delivers the strongest compliance posture of any proxy API provider in the market. SOC 2 Type II, ISO 27001, and EU jurisdiction make it the only proxy API that passes enterprise procurement reviews in regulated industries.
The Python SDK is the cleanest in the category, with OxyCopilot AI assistant built in for query construction and pipeline debugging. Oxylabs fits enterprise data engineering teams, finance and healthcare organisations running legal scraping operations, and any team where procurement requires documented compliance before vendor approval.
Oxylabs Proxy API Highlights
- IP Pool: 102 million residential IPs at 99.99% uptime across 195 countries
- Compliance: SOC 2 Type II, ISO 27001, EU jurisdiction — the strongest in the category
- SDK Quality: Python SDK rated the cleanest in the proxy API category with OxyCopilot AI assistant
- Sticky Sessions: Up to 24 hours on a single peer IP, longest available in the market
- Web Scraper API: JavaScript rendering, automatic retries, and anti-detection built on top of residential IPs
What You Pay
Residential proxy API from approximately $15/GB at entry. Web Scraper API from $49/month with 2,000 results free trial — no credit card required. Enterprise commitments reduce per-GB rates by 40 to 60%. Mobile proxy API from $20/GB.
Pros
- 24-hour sticky sessions suit long-running account automation that Decodo's 30-minute limit cannot handle
- ISO 27001 alongside SOC 2 Type II passes regulated industry procurement where Decodo cannot
- Web Scraper API free trial at 2,000 results lets you test against real targets before committing
Cons
- Entry residential pricing at $15/GB is roughly 7x Decodo's $2.20/GB for the same IP type
- 17.5-second average response time in independent tests significantly trails Decodo's 0.54 seconds
- Pricing tiers require a conversation with sales for anything above the standard published plans
Why Oxylabs for Proxy API Oxylabs is the only proxy API provider that can simultaneously satisfy enterprise procurement, legal compliance, and serious scraping performance requirements. If you operate in finance, healthcare, or any EU-regulated environment, Oxylabs is not optional — it is the only provider with the documentation your vendor review process requires.
3. Bright Data
Bright Data operates the most complete proxy API ecosystem available in 2026. Beyond the 72 million residential IPs, the platform includes a Web Unlocker for Cloudflare-protected targets, a Browser API for JavaScript-heavy pages, a no-code Web Scraper IDE with 120 pre-built scrapers, and a Datasets marketplace with ready-made structured data. No other proxy API provider bundles this breadth into one platform.
Bright Data fits teams that need more than raw proxy access — specifically LLM data enrichment pipelines, SERP tracking at scale, market intelligence operations, and enterprise data teams that want managed solutions rather than building infrastructure from scratch.
Bright Data Proxy API Highlights
- IP Pool: 72 million residential IPs with 150 million total IPs across all network types
- Web Unlocker: Automated anti-bot bypass layer that handles Cloudflare, Akamai, and DataDome without custom code
- Browser API: Full headless browser with residential exit nodes for JS-heavy target scraping
- No-Code Scraper IDE: 120 pre-built scrapers for common targets including Amazon, LinkedIn, and Google
- Datasets Marketplace: Ready-structured datasets available for purchase without scraping infrastructure
What You Pay
Residential proxy API from $10.50/GB. Web Unlocker from $3/1,000 requests. Browser API from $15/1,000 sessions. Datasets marketplace pricing varies by dataset. Free trial available with contact form submission.
Pros
- Web Unlocker handles Cloudflare Bot Fight Mode without custom anti-detection code — no other provider matches this
- 120 pre-built no-code scrapers eliminate development time for common commercial targets
- Datasets marketplace lets non-engineering teams buy structured data without proxy infrastructure
Cons
- Residential proxy API at $10.50/GB is 4.8x Decodo's price for equivalent IP type and similar success rates on standard targets
- Free trial requires a contact form submission and sales process, not instant access like Webshare
- Platform complexity requires a learning curve that smaller teams often underestimate in their first month
Why Bright Data for Proxy API Bright Data is the right proxy API when raw IP access is not enough. The Web Unlocker, Browser API, and no-code scraper IDE collectively solve problems that proxy IPs alone cannot handle. If your targets include Cloudflare-protected e-commerce, LinkedIn, or any JS-rendered target that requires a real browser, Bright Data’s platform layer saves more in development time than the premium pricing costs.
4. Webshare
Webshare built its reputation on one thing that the rest of this list largely ignores — a free tier that actually works for testing. Ten proxies and 1 GB of bandwidth per month with no credit card required gives you enough to validate the proxy API against your actual targets before spending anything. The API itself is consistently rated the cleanest and most straightforward in the category.
Webshare fits developers building custom proxy integrations, technical teams prototyping before committing to enterprise providers, and scraping operations under $500 per month that do not need mobile carrier IPs or extreme anti-bot capability.
Webshare Proxy API Highlights
- Free Tier: 10 proxies plus 1 GB bandwidth per month — no payment details, no KYC, no sales call required
- API Design: REST API rated the most straightforward integration in the proxy API category
- Residential Pricing: $0.99/GB residential on base plans — cheapest among providers with documented ethical sourcing
- Onboarding Speed: 60-second account setup with immediate API key generation
- Protocol Support: HTTP, HTTPS, and SOCKS5 across residential and datacenter pools
What You Pay
Free plan includes 10 shared proxies plus 1 GB bandwidth per month. Residential proxy API from $0.99/GB on starter plans. Business plans from $2.99/GB with higher quality tiers. Static residential from $0.285/IP on annual plans.
Pros
- Free tier gives real residential API access for testing with zero financial commitment
- $0.99/GB residential pricing is the cheapest in the market among ethically sourced providers
- 60-second signup with no KYC is the lowest-friction onboarding of any provider on this list
Cons
- Datacenter ASNs are flagged at the network layer by Cloudflare and Akamai — success rate drops to 30 to 50% on Bot Fight Mode targets regardless of header configuration
- Residential pool is thinner in LATAM, MENA, and Southeast Asia, causing IP repetition on rotation in smaller markets
- No mobile carrier IPs — teams that need 4G or 5G carrier exit nodes must go elsewhere
Why Webshare for Proxy API Start here. The free tier is not a demo — it is real proxy API access that tells you definitively whether Webshare handles your targets before you spend a dollar. For general scraping, SEO rank tracking, and ad verification under $500 per month, Webshare’s API and pricing are hard to beat. Graduate to Decodo or Bright Data when your targets start running Akamai Bot Manager v2 or PerimeterX with custom signals.
5. NetNut
NetNut takes a fundamentally different approach to residential proxy API infrastructure. Instead of routing traffic through peer devices that share bandwidth from their home connections, NetNut sources IPs directly from ISP partnerships. The result is ISP-level IPs that appear as legitimate residential addresses to target sites but operate at datacenter speeds without the latency variability that peer-sourced residential IPs introduce.
NetNut fits teams running price monitoring operations, market research with predictable session patterns, and any workflow where stable IP performance matters more than extreme pool diversity. The ISP-direct model also removes the ethical questions around peer SDK sourcing entirely.
NetNut Proxy API Highlights
- IP Source: Direct ISP partnerships rather than peer SDK integrations — no peer consent dependencies
- IP Pool: 52 million ISP-sourced residential IPs across 100 countries
- Speed: ISP-direct routing eliminates peer latency variability for more consistent response times
- Datacenter Entry: Datacenter proxy API from $0.45/GB — lowest datacenter rate among reviewed providers
- Session Stability: Static ISP IPs available for consistent, repeatable monitoring workflows
What You Pay
Datacenter proxy API from $0.45/GB — the lowest datacenter rate on this list. ISP residential proxy API pricing contact-based for volume commitments. Residential from $3/GB on standard plans. 7-day free trial available.
Pros
- $0.45/GB datacenter pricing undercuts every other provider on this list for non-residential use cases
- ISP-direct sourcing means zero peer consent dependency risks that affect SDK-based residential networks
- Static ISP IPs provide session consistency that rotating peer residential cannot match for monitoring workflows
Cons
- 52 million ISP IPs is a smaller pool than Decodo at 115 million or Oxylabs at 102 million
- Country coverage at 100 nations is narrower than the 195-country standard from the top three providers
- Pricing beyond the datacenter tier requires a sales conversation rather than instant self-serve access
Why NetNut for Proxy API NetNut solves a specific problem better than anyone else on this list. If you need consistent, stable IP sessions for price monitoring or market research workflows where repeatability matters more than pool diversity, the ISP-direct architecture delivers performance that peer residential networks cannot. The $0.45/GB datacenter rate also makes it the obvious choice when your targets do not require residential IPs.
6. DataImpulse
DataImpulse positions itself as an enterprise-oriented proxy API provider that is actually accessible to mid-sized teams through non-expiring traffic on its pay-per-GB model. Most providers expire unused bandwidth at the end of the billing period. DataImpulse does not. Every GB you buy stays in your account until you use it, which removes the budget pressure of monthly bandwidth commitments.
DataImpulse fits data engineering teams with irregular scraping schedules, operations that run intensive bursts followed by quiet periods, and enterprise procurement environments that want compliance documentation alongside flexible billing.
DataImpulse Proxy API Highlights
- Non-Expiring Traffic: Purchased bandwidth never expires — unused GB carries forward indefinitely unlike every other provider on this list
- IP Pool: 7 million residential IPs across 150+ countries with ASN and ZIP-level targeting
- Compliance: Enterprise vendor documentation available for procurement review processes
- Targeting Precision: ASN and ZIP-level geo-targeting — more granular than country or city targeting alone
- API Access: Full REST API with usage analytics and rotation management
What You Pay
Residential proxy API from $7.35/GB with non-expiring traffic on pay-per-GB model. Priority support available on subscription tiers. No free tier but paid trial available. Enterprise volume pricing on request.
Pros
- Non-expiring traffic is a genuine differentiator — no other provider on this list offers it
- ASN and ZIP-level targeting goes deeper than city-level geo-precision from most competitors
- Enterprise documentation makes procurement approval easier than with budget providers
Cons
- No controlled scraping API or ready-to-go scraping endpoints — raw proxy API only
- Does not provide data from banking or government websites, limiting use cases in regulated data categories
- $7.35/GB residential pricing is higher than Decodo at $2.20/GB for a smaller 7 million IP pool
Why DataImpulse for Proxy API The non-expiring traffic model is the single most underrated feature in the proxy API market. If your scraping workload is unpredictable — heavy one month, light the next — DataImpulse removes the budget waste of paying for bandwidth you did not use. No other provider on this list solves that problem.
7. Proxy-Seller
Proxy-Seller covers more ground than any other provider on this list. Five proxy types — datacenter IPv4, datacenter IPv6, ISP, residential, and 4G/5G mobile — across 220 countries, 400 networks, and 800 subnets. For teams that need geo-targeted proxy API access in markets where the top three providers have thin coverage, that breadth is the entire value proposition.
Proxy-Seller fits location-specific scraping operations targeting emerging markets, teams managing diverse proxy type requirements across different client workflows, and anyone who has hit coverage gaps with the more focused providers.
Proxy-Seller Proxy API Highlights
- Geographic Coverage: 220 countries across 400 networks and 800 subnets — widest coverage on this list
- Proxy Types: All five types available — datacenter IPv4, IPv6, ISP, residential, and 4G/5G mobile in one dashboard
- Mobile Coverage: 4G/5G mobile carrier IPs across 20+ countries with carrier-level targeting
- Entry Pricing: Datacenter IPv4 from $0.90/IP, IPv6 from $0.08/IP, residential from $3.50/GB
- API Management: Order creation, pricing calculation, balance management, and renewal via API
What You Pay
Datacenter IPv4 from $0.90 per IP. Datacenter IPv6 from $0.08 per IP. ISP proxies from $1.50 per IP. Residential proxy API from $3.50/GB. Mobile proxies from $14/GB. 10-plus years operating with 500,000 total clients served.
Pros
- 220-country coverage fills geographic gaps that leave Decodo and Oxylabs producing repeated IPs in smaller markets
- Single dashboard for all five proxy types removes the need for multiple provider accounts across different use cases
- $0.08/IP for IPv6 is the cheapest IPv6 access of any provider reviewed
Cons
- Residential pool size not publicly disclosed — makes direct IP count comparison with competitors impossible
- Mobile carrier proxy API at $14/GB is expensive relative to the residential tier and limited to 20 countries
- Customer support response times trail the enterprise providers — Bright Data and Oxylabs both offer faster resolution
Why Proxy-Seller for Proxy API Proxy-Seller wins specifically when geographic breadth or proxy type diversity is the constraint. If you need a single proxy API provider that covers LATAM, MENA, and Southeast Asia reliably while also giving you mobile carrier IPs and ISP proxies from one dashboard, Proxy-Seller is the only option on this list that delivers all of that without forcing multiple vendor relationships.

How to Choose the Right Proxy API for Your Workflow
The market has split into three clear pricing tiers in 2026. Enterprise providers — Bright Data and Oxylabs — run at $8.50 to $15 per GB with full compliance documentation and managed scraping layers.
Mid-market providers — Decodo, NetNut, and DataImpulse — run at $2.20 to $7.35 per GB with strong residential pools and flexible billing. Budget providers — Webshare, IPRoyal — start below $1 per GB with trade-offs on pool depth and anti-bot capability.
The decision framework is straightforward. If your targets are protected by Cloudflare Bot Fight Mode or PerimeterX with custom signals, go straight to Bright Data’s Web Unlocker or Oxylabs’ Web Scraper API — raw residential IPs will not solve that problem regardless of how many you rotate.
If your targets are standard e-commerce, price monitoring, or SEO data, Decodo at $2.20/GB delivers 99.68% success at a fraction of the enterprise cost. If you are still prototyping, start with Webshare’s free tier and graduate once you know exactly what you need.
Premium proxy API providers at $10 to $15 per GB offer 98 to 99% success rates. Budget providers deliver 85 to 92% success rates on the same targets. On a 10,000 daily request operation, that 7 to 14 percentage point gap translates into 700 to 1,400 failed requests per day that your pipeline has to retry or lose.
Calculate the cost of those failures against the price difference before defaulting to the cheapest option.
