Look up a public GitHub repository by "owner/name" slug. Returns full name, owner, description, homepage, default branch, primary language, topics, license (SPDX key + name), counts (stars / forks / watchers / open issues / subscribers / network), size, timestamps (created/updated/pushed), visibility, has-issues/projects/wiki/discussions flags. Unauthenticated GitHub access is rate-limited to 60 req/hour per server IP — returns 429 UPSTREAM_RATE_LIMIT when the bucket is empty.
/api/code/repo-lookupPAYMENT-SIGNATURE.The repo lookup API is a pay-per-call code endpoint built for AI agents and autonomous software. Look up a public GitHub repository by "owner/name" slug.
There is no signup and no API key. An agent (or any HTTP client) hits the endpoint, receives an x402 "402 Payment Required" challenge, signs a sub-cent USDC payment on Base or Solana, and retries — the data comes back on the paid request. That makes it a drop-in repo lookup data source for an agent tool-use loop, an MCP host, or a backend that needs code data on demand without onboarding to yet another vendor portal.
