gitBeacon — GitHub Trend Intelligence for AI Agents

API at https://api.gitbeacon.dev (website https://gitbeacon.dev). gitBeacon watches new repositories that trend on GitHub each day, enriches each candidate (stars, forks, language, topics, license, author followers, README excerpt), and has an LLM synthesize the day into a structured digest — dominant categories of work, emerging tools and frameworks, language-popularity trends, the most notable projects, and an overall sentiment. Strictly pay-per-call via x402 — no accounts, no API keys, no bundles. Compute-first / settle-after: you are never charged for an error.

gitBeacon is the GitHub-trends intelligence product spun out of moltalyzer. The old paths /api/github/* on api.moltalyzer.xyz 308-redirect here until 2026-09-08 — point new integrations at api.gitbeacon.dev.

Free endpoints (no auth, no payment)

Poll for free to detect new digests and learn every response shape before paying. /v1/sample is a FROZEN sample digest (captured from the 2026-02-13 scan) — the same shape as a real digest, but it never changes and is labelled as such, so it is safe for testing without implying live data.

Paid endpoints (x402 V2, USDC on Base only, per-call)

Each paid call is a flat price per call, settled per call via x402. Networks: Base Mainnet only (eip155:8453). Compute-first / settle-after — you are never charged for an error.

Params for /v1/repos: limit (integer 1-100, default 30), language (case-insensitive language filter, e.g. Python, Rust, TypeScript). Params for /v1/digests: days (integer 1-30, default 7), limit (integer 1-30, default 7). All prices are USD, settled as USDC (6 decimals) on Base.

Paying (x402)

Paid routes settle per call via x402 V2. The only accepted rail is USDC on Base Mainnet (eip155:8453) — no other network. No account, no signup, no API key.

Pay flow:

1. Call the paid route with no payment → receive HTTP 402. The x402 V2 PaymentRequirements ride in the base64 PAYMENT-REQUIRED header; the JSON body mirrors the price + accepts.
2. Sign an EIP-3009 exact USDC authorization on Base for the accepts[] amount.
3. Retry the same request with the payment in the PAYMENT-SIGNATURE (V2) or X-PAYMENT (legacy) header.

# 1. Probe for the 402 challenge (price + accepts):
curl -i "https://api.gitbeacon.dev/v1/repos?limit=30&language=Python"
# → HTTP/1.1 402 Payment Required, PAYMENT-REQUIRED header (base64 requirements)

# 2. Sign + retry with a stock x402 client (handles the whole flow):

import { wrapFetchWithPayment } from "@x402/fetch";
import { createWalletClient, http } from "viem";
import { privateKeyToAccount } from "viem/accounts";
import { base } from "viem/chains";

const account = privateKeyToAccount(process.env.PRIVATE_KEY as `0x${string}`);
const wallet = createWalletClient({ account, chain: base, transport: http() });
const fetchWithPay = wrapFetchWithPayment(fetch, wallet); // signs EIP-3009 on 402, retries

// $0.01 — top trending repos, filtered to Rust:
const repos = await fetchWithPay(
  "https://api.gitbeacon.dev/v1/repos?limit=30&language=Rust",
).then((r) => r.json());
// repos.scanDate, repos.count, repos.data[] (fullName, stars, language, topics, readmeExcerpt, …)

// $0.05 — historical digests, last 7 days:
const digests = await fetchWithPay(
  "https://api.gitbeacon.dev/v1/digests?days=7&limit=7",
).then((r) => r.json());

Stock x402 clients (@x402/fetch, @x402/axios, python x402) do the 402 → sign → retry automatically. Discover the machine-readable route + price catalog at /.well-known/x402.

Free funnel

Try every response shape for free before you pay. Poll /v1/index (10/min) to detect a new digest on its ~24h cadence; read /v1/brief (10/min) for the trimmed current digest or /v1/digests/latest (5/min) for the full latest digest; hit /v1/sample (5/min) for the frozen 2026-02-13 digest to learn the exact response contract before spending. The paid /v1/repos and /v1/digests carry scanDate/digestDate provenance so you always know how fresh the data is.
