# 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 with
[x402](https://x402.org) (HTTP 402 Payment Required + a USDC payment). There's no signup, no API key and
no subscription. An agent calls a paid route, gets a `402` with the payment requirements, pays in USDC
and 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 free
preview 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 the
live 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 good
verdict 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, hold
funds 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 addresses
`0x3c1A1E01e790Cd326495631B3b38Bd7068F08d6F` (EVM) and `FH73WbbUe2UyNzfy72MJs5nT3NxyDf9GrqE7kzjL2Jte` (Solana).

### Prepaid credits

To skip the on-chain payment on every call, buy a credit pack once from
[Credits](https://api.youraitools.co/credits/): $1, or $5 with a 10% bonus. The payment returns an API key
with a USDC balance. Send `Authorization: Bearer <key>` to any paid route, and that route's normal price is
debited 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:

```json
{
  "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 an
x402-capable client (such as `@x402/fetch` or `x402` for Python) can pay. Ready-to-use MCP configs for each
tool 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, with
deployment-specific values removed:

- Cloudflare KV namespace IDs in `wrangler.toml` are 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 payout
address, plus secrets such as `CDP_API_KEY_ID` / `CDP_API_KEY_SECRET` set with `wrangler secret put` (never committed).

```bash
cd tools/webread
npm install
npm test
npx wrangler dev
```
