How to access huggingface.co as an agent
- ○Check for an undocumented developer API
No OpenAPI at the standard paths. Look for /developer, /developers, /docs, /api for hand-authored documentation.
https://huggingface.co/developers - ●Register an OAuth application
OAuth/OIDC discovery is published. Register a client, pick narrow scopes, implement signature verification on webhooks.
https://huggingface.co/.well-known/oauth-authorization-server - ○Publish your own agent identity
Generate an Ed25519 keypair, host a public key directory, sign your HTTP requests (Web Bot Auth), apply to Cloudflare's bots & agents directory if you cross their edge.
https://developers.cloudflare.com/bots/concepts/bot/verified-bots/ - ●Respect robots.txt and Content Signals
Even when you are an approved agent, honor the site's policy preferences. Cache them; refresh weekly.
