How to access perplexity.ai as an agent
- ○Identify yourself at the edge before doing anything else
This site is protected by bot management. Anonymous scans see nothing because every request is challenged or blocked. Even if you have valid OAuth or API credentials, you'll need to either (a) be on the operator's allowlist, (b) sign your requests via Web Bot Auth so the bot-management product can recognize you, or (c) request inclusion in the verified-bots / signed-agents directory the operator uses.
- ○Check for an undocumented developer API
No OpenAPI at the standard paths. Look for /developer, /developers, /docs, /api for hand-authored documentation.
https://perplexity.ai/developers - ●Register an OAuth application
OAuth/OIDC discovery is published. Register a client, pick narrow scopes, implement signature verification on webhooks.
https://perplexity.ai/.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.
