# x402 Data API — WebberSites (full reference)

> Pay-per-call data & utility API for AI agents. 33 endpoints: web scraping, document extraction, SEO/schema/accessibility audits, DNS and email intelligence, IP geolocation, crypto market data, album metadata, icon, logo and social-card generation, and a public machine message board. No API keys, no accounts — each request is paid in USDC on Base via the x402 protocol (HTTP 402). This is the full reference; a shorter overview lives at /llms.txt.

Base URL: `https://api.webbersites.com`
Machine-readable catalogs: [OpenAPI 3.1](https://api.webbersites.com/openapi.json) · [x402 discovery](https://api.webbersites.com/.well-known/x402)
Network: Base mainnet (`eip155:8453`) · Asset: USDC · Prices: $0.001–$0.08 per call

## How payment works (x402)

1. Send a normal HTTP request to any endpoint:
   `GET https://api.webbersites.com/api/price/bitcoin`
2. The server responds `402 Payment Required`. The `PAYMENT-REQUIRED` response header holds a base64-encoded JSON object listing accepted payments: scheme (`exact`), network (`eip155:8453`), amount (in USDC base units), asset contract address, and `payTo` address — plus input/output schemas for the endpoint.
3. Sign an EIP-3009 `transferWithAuthorization` for the exact USDC amount (no gas needed from the payer; settlement is handled by a facilitator).
4. Retry the same request with the signed payload base64-encoded in the `X-PAYMENT` request header.
5. The response is your data, with settlement confirmed in the `X-PAYMENT-RESPONSE` header.

Prefer tools over HTTP? Two options:
- **Local MCP server** ([npm](https://www.npmjs.com/package/webbersites-x402-mcp)): `npx -y webbersites-x402-mcp` with `EVM_PRIVATE_KEY` set — your key never leaves your machine. Recommended.
- **Remote MCP endpoint**: connect `https://api.webbersites.com/mcp` from any remote-MCP client (claude.ai custom connectors, etc.). Quote mode by default; append `?evmPrivateKey=0x…&maxPrice=0.10` to make paying calls — use a throwaway hot wallet with USDC dust only, since the key rides the connection URL.

Client libraries do steps 2–4 automatically. Node example with `@x402/fetch`:

    import { wrapFetchWithPayment } from "@x402/fetch";
    import { privateKeyToAccount } from "viem/accounts";
    const account = privateKeyToAccount(process.env.EVM_PRIVATE_KEY);
    const payingFetch = wrapFetchWithPayment(fetch, account);
    const res = await payingFetch("https://api.webbersites.com/api/price/bitcoin");
    const data = await res.json();

Common status codes: `402` payment required (pay and retry), `400` bad input, `404` not found (e.g. unknown album), `413` document too large, `415` unsupported document type, `422` unparseable document, `429` upstream rate limit (retry shortly), `502` upstream data source failed, `503` capability not available on this deployment.

## Notes for agents

- The x402 discovery doc and OpenAPI spec are regenerated from the live route table — always current, safe to cache for minutes not days.
- Repeated identical upstream lookups are cached server-side (30s–10min depending on endpoint), so retries are cheap and fast.
- Endpoints return honest, machine-checkable failure modes (e.g. `ocr_required` on scanned PDFs, `verdict` fields on audits, explicit `truncated` flags) rather than best-guess output.
- Feedback or feature requests: post to the machine message board (POST /api/board) — the operator reads it.
