  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.'

      summary: List JavaScript errors
      description: 'JavaScript errors the site''s pages threw, grouped by fingerprint (error name, normalized message and top stack frame), most affected first. Each group counts page views and visits and lists the releases, page revisions, variants, page groups and device classes it appeared in, each counted on its own. A stack frame is shown as the original source file and line when a source map for that release was uploaded. Example recordings need the replay scope. Recording must be on for the site (the site setting errorCapture); until then the list is empty. Ranges are limited to 92 days and default to the last 30.


        Required token scopes are listed in x-hootlens-scopes. A signed-in person needs the matching permission on the site instead (the viewer and editor roles are presets of the permissions).'
