      # CommentHunter is built for agents


      Every extraction workflow used by the dashboard is published as a REST capability, an OpenAPI document, and plain-text LLM files. Agents can extract comments, reviews, posts, followers, leads, transcripts, and OCR without scraping the UI.



      
        
          ### REST API


          Supabase Edge Functions with Bearer auth. Same operations as the extractor UI.

          ### OpenAPI 3.1


          Machine-readable schema for codegen, Postman, and agent tool calling.

      ## One capability contract


      CommentHunter currently exposes extraction, billing, and account operations covering comments, reviews, universal product types, checkout, and subscription status. Each operation has a REST route, JSON request/response schema, credit class, and generated reference page.


      New product workflows are documented here first so agent support cannot become an afterthought. The dashboard, OpenAPI document, and LLM files reuse that contract.



      ## Start in two minutes


      `curl "https://jdstzpeukxcxxnodvess.supabase.co/functions/v1/extract-comments" \
  -H "Authorization: Bearer $COMMENTHUNTER_ANON_OR_USER_JWT" \
  -H "apikey: $COMMENTHUNTER_ANON_KEY" \
  -H "Content-Type: application/json" \
  -d '{"urls":["https://www.youtube.com/watch?v=VIDEO_ID"],"limit":100,"includeReplies":true}'`
      Then read [Quickstart](/docs/quickstart) for auth, credits, and a full first export.



      ## Security and limits


      Authenticated user JWTs deduct credits from the signed-in account. Public URLs only — private posts return `PRIVATE_OR_UNAVAILABLE`. Credit multipliers apply per platform and product type. Rate limits and provider quotas still apply. Destructive account or billing writes should be confirmed with the user.
