title: Hoot Lens Recordings API
version: v1
summary: Read website interaction evidence and log changes.
description: 'The Hoot Lens REST API records website interaction evidence for the sites you add and returns it as visits, recordings, heatmaps, goals, funnels and change impact. This document describes the endpoints a person or an agent uses to read that evidence and to log changes. Everything returned is observed behavior with its evidence; the API makes no claims about visitors'' emotions or intent.
Authentication. Send `Authorization: Bearer `. The credential is either a Firebase ID token (a signed-in person, whose role on each site decides what they may do) or a personal access token (`hl_pat_...`) made in the dashboard. A personal access token carries the scopes `read`, `replay` and `annotate`, belongs to one site, expires in 30, 60 or 90 days, and can do no more than its creator''s current role allows. Operations marked `x-hootlens-sign-in-only` need a signed-in person and answer 403 to a token.
OAuth. The hosted MCP endpoint (`/mcp`, Streamable HTTP) signs assistants in with OAuth 2.1 authorization code and PKCE (S256), with discovery at `/.well-known/oauth-protected-resource` and `/.well-known/oauth-authorization-server`. Its access tokens (`hl_oat_...`) are bound to the MCP resource and are accepted only there; sending one to any route in this document answers 401. Use a personal access token or a Firebase ID token for these routes.
Not described here. Collector intake, public tracker configuration, billing, OAuth, sharing links, issues and feedback, invitations, members, access tokens, notifications and the audit log also exist; see docs/API.md for them.
Site (project) IDs are public. Authorization is enforced by the API on every request. Rate limits answer 429. A caller who is not a member of a site receives 404, so a site''s existence is not revealed.'
