GateSolve is a CAPTCHA solving API designed for AI agents. Get 100 free solves with an API key, then pay per solve with USDC. Supports Cloudflare Turnstile, reCAPTCHA v2/v3, and hCaptcha.

How does x402 payment work?

When an agent sends a solve request, GateSolve returns HTTP 402 with payment details. The agent pays the specified USDC amount on Base network, includes the payment proof in the header, and gets the CAPTCHA solution back.

What CAPTCHA types does GateSolve support?

GateSolve supports Cloudflare Turnstile, reCAPTCHA v2, reCAPTCHA v3, and hCaptcha. Average solve time is 8-15 seconds. Available via REST API, Python SDK, MCP server, Playwright, Puppeteer, and Selenium plugins.

Why GateSolve is different

Most CAPTCHA solving services were built for web scrapers — they require manual account creation, prepaid balances, and REST-only APIs. GateSolve was built from day one for AI agents.

Free tier: 100 solves per API key, no credit card required
Agent-native tools: MCP server, Python SDK, Playwright plugin, Puppeteer plugin, Selenium plugin
Async API: Submit → poll (or webhook callback) — designed for non-blocking agent workflows
Micropayments: Pay per solve with USDC via x402 protocol after free tier
Block detection: Pre-flight URL classification (captcha, auth-wall, js-challenge) — know what you are hitting before burning credits
Dry-run validation: Test your solve request without consuming credits or creating a job
30-second setup: Get an API key and start solving immediately

How to Choose a CAPTCHA Solving Service in 2026

The CAPTCHA solving market has evolved significantly. Traditional services like 2Captcha rely on human workers, offering broad CAPTCHA type coverage but slower solve times (15-45 seconds). AI-based services like CapSolver and CAP Monster use machine learning for faster solves (3-15 seconds) on token-based CAPTCHAs. GateSolve combines AI-based solving with an agent-first architecture — free tier, async API, webhook callbacks, and native integrations for every major automation framework.

GateSolve vs CapSolver

CapSolver offers competitive pricing ($0.80/1K for reCAPTCHA v2) and fast solve times. GateSolve differentiates with a generous free tier (100 solves, no credit card), native MCP server for AI agent frameworks, and Playwright/Puppeteer/Selenium plugins. For AI agent builders, GateSolve requires zero upfront payment and integrates in 30 seconds.

GateSolve vs 2Captcha

2Captcha uses human workers for reliable solving across all CAPTCHA types including image CAPTCHAs. Solve times are slower (15-45s) and require a minimum $3 prepaid balance. GateSolve offers faster AI-based solving for token CAPTCHAs (Turnstile, reCAPTCHA, hCaptcha) with 100 free solves and no minimum payment.
