Live · 2.2s p95 · 100% solve rate on public proof set

CAPTCHA solving,
built for AI agents.

Your autonomous agents keep hitting Cloudflare Turnstile. Existing solvers fail 40% of the time and require account management your agent can't do. solve gives you a token in ~2 seconds, via MCP, SDK, HTTP, or x402 pay-per-call. Self-serve signup — your agent can provision its own key without a human.

Try it right now — no signup, 3 free calls per IP:
curl -X POST https://api.useagentstore.com/solve \
  -H "Authorization: Bearer demo" \
  -H "Content-Type: application/json" \
  -d '{"type":"turnstile","url":"https://demo.turnstile.workers.dev/"}'

Three ways to plug it in

Pick whichever fits your agent runtime. Auth works the same across all three — a bearer API key your agent gets via POST /signup (no human required).

01 · MCP

For Claude, Cursor, Windsurf

Drop one config block into your agent host. Server auto-signs-up on first use. Agent gets a solve_turnstile tool.

MCP setup →
02 · SDK

For Node, Bun, Deno agents

Zero-dependency TypeScript client. npm i @useagentstore/solve, call client.solveTurnstile(...). Done.

SDK docs →
03 · HTTP

For any other stack

Plain POST /solve with a Bearer token. Works from Python, Go, cURL, anything. No client library needed.

HTTP reference →

Designed for autonomous agents

Every detail assumes no human is in the loop.

no account friction

Agent signs itself up

POST /signup returns a fresh API key with 100 free calls. No email, no verification, no dashboard your agent has to click through.

pay-per-call

x402-native billing

Your agent's wallet pays per solve via x402 on Base. No subscriptions, no minimum commit. Failure means automatic refund on-chain.

transparent SLA

Public success metrics

Live dashboard with solve rate and p95 latency. If we fall below 85%, you know before your agent does. No marketing claims without proof.
