YourAITools: pay-per-call x402 tools for AI agents
YourAITools is a set of small, single-purpose APIs that AI agents pay for per call withx402 (HTTP 402 Payment Required + a USDC payment). There's no signup, no API key andno subscription. An agent calls a paid route, gets a 402 with the payment requirements, pays in USDCand gets the answer.
- API: https://api.youraitools.co (each tool lives under its own path, e.g.
https://api.youraitools.co/webread/) - Website and directory: https://youraitools.co
- Browsable source mirror: https://agentgate-source.pages.dev
Every tool in this repository is a Cloudflare Worker (Hono, x402 v2 with a v1 fallback), with a freepreview route, OpenAPI, /.well-known/x402 discovery, a remote MCP server at /mcp and, for most tools,a stdio MCP server.
Tools
Prices are in USDC per call. They come from each tool's wrangler.toml / src/config.js and match what thelive API charges today. GET|POST means both methods are accepted at the same price.

Safety tools (PayGuard, TokenVerdict, SignCheck, CounterpartyCheck, SolVerdict, PkgGuard, InjectScan,LeakGuard, DomainCheck): each result is a safety check, not a guarantee and not financial advice. A goodverdict means the checks found nothing wrong. It does not mean an asset, address or package is safe.
Trader tools (PerpRadar, TASignal): read-only market analytics and simulation. They never trade, holdfunds or touch keys. Not financial advice. Past performance does not guarantee future results.
Payments and chains
Paid routes accept USDC on:
- Base (
eip155:8453) - Polygon (
eip155:137) - Arbitrum One (
eip155:42161) - Solana mainnet (
solana:5eykt4UsFv8P8NJdTREpY1vzqKqZKvdp)
Every 402 response lists all four in accepts (x402 v2, PAYMENT-REQUIRED header). x402 v1 (X-PAYMENT)is supported on Base. Payments settle to the public payout addresses0x3c1A1E01e790Cd326495631B3b38Bd7068F08d6F (EVM) and FH73WbbUe2UyNzfy72MJs5nT3NxyDf9GrqE7kzjL2Jte (Solana).
Prepaid credits
To skip the on-chain payment on every call, buy a credit pack once fromCredits: $1, or $5 with a 10% bonus. The payment returns an API keywith a USDC balance. Send Authorization: Bearer <key> to any paid route, and that route's normal price isdebited from the balance. Credits are for prepaid API usage only and are not refundable.
Using the tools from an MCP client
Each tool runs a remote MCP server (Streamable HTTP) at https://api.youraitools.co/<tool>/mcp. For example:
{
"mcpServers": {
"webread": { "url": "https://api.youraitools.co/webread/mcp" },
"leakguard": { "url": "https://api.youraitools.co/leakguard/mcp" }
}
}
The free preview tools work without payment. Paid tools return the x402 payment requirements, which anx402-capable client (such as @x402/fetch or x402 for Python) can pay. Ready-to-use MCP configs for eachtool are in its folder (server.json / glama.json where present, and the README).
Repository layout
tools/<name>/ one folder per tool: src/, test/, README.md, package.json, wrangler.toml, Dockerfile, logo
Each folder is an exact export of that tool's published commit on agentgate-source.pages.dev, withdeployment-specific values removed:
- Cloudflare KV namespace IDs in
wrangler.tomlare replaced with"<your-kv-id>" - internal paths and notes are removed from comments
- internal test-payment scripts are left out
To run a tool yourself, follow its README. You'll need your own Cloudflare account, KV namespace and payoutaddress, plus secrets such as CDP_API_KEY_ID / CDP_API_KEY_SECRET set with wrangler secret put (never committed).
