GitHub repository enrichment

Enrich a public GitHub repository: stars, forks, watchers, open issues, license, topics, primary language plus the full language byte mix with percentages, created/last-push timestamps, default branch, archived/fork flags, and homepage. Send POST /api/github-repo with the required fields owner and repo and pay $0.005 per call over x402 or MPP (there is no free tier). It returns a JSON object with fullName, description, stars, forks, watchers and 13 more.

Keyless (shared per-IP rate limit; the server optionally uses a GITHUB_TOKEN env var for a higher ceiling). Unknown repos return 404.

Parameters

Example request

curl -i -X POST https://agent402.tools/api/github-repo \
  -H "Content-Type: application/json" \
  -d '{"owner":"expressjs","repo":"express"}'

Without payment this returns HTTP 402 Payment Required with the exact price for github-repo; any x402 v2 or MPP client pays it and retries.

    "owner": "expressjs",
    "repo": "express"
  }
}

The hosted connector at https://agent402.tools/mcp needs a payment for github-repo; the stdio package pays it from a wallet or from an AGENT402_CREDITS_KEY issued earlier. Local install: npx -y agent402-mcp.

Errors and behavior

• owner and repo are required. An input the tool rejects returns an HTTP 4xx whose body carries error, tool, expected, required and example, so the caller can correct it.
• A paid call that ends in any status of 400 or above is not charged over x402, MPP or a prepaid credits key: settlement is cancelled when the tool fails. The exception is a Tempo push credential, a transfer the buyer sent before the call: it settles before the tool runs, so if the tool then fails the payment is recorded as a refund owed to the paying wallet.
• Wallet-only: this tool reaches the network or stored state, so it has no proof-of-work tier. A prepaid card-credits key issued earlier (Authorization: Bearer a402_...) also pays it.
• A GET or HEAD to /api/github-repo returns the same 402 quote, so the price can be read without a body.
• An Idempotency-Key header makes a retried paid call replay the first 200 instead of charging again (an answer larger than 1 MB is not replayed).

Paid call (JavaScript agent)

import { wrapFetchWithPayment } from "@x402/fetch";
import { x402Client } from "@x402/core/client";
import { registerExactEvmScheme } from "@x402/evm/exact/client";
import { privateKeyToAccount } from "viem/accounts";

const client = new x402Client();
client.setSpendControls?.({ maxAmountPerPayment: "$0.005" }); // refuse any quote above this tool's price
registerExactEvmScheme(client, { signer: privateKeyToAccount(KEY) });
const payFetch = wrapFetchWithPayment(fetch, client);

const res = await payFetch("https://agent402.tools/api/github-repo", {
  method: "POST",
  headers: { "Content-Type": "application/json" },
  body: JSON.stringify({
    "owner": "expressjs",
    "repo": "express"
  }),
});
