HTTP API Reference

This is the complete index of Talkshi's supported public HTTP contracts. Use the focused page linked from each row for fields, examples, limits, and response shapes. Routes not listed here are deployment or operations plumbing, not a public integration contract.

Reviews and participation

Method and URL Authentication Contract
POST https://write.talkshi.com/review verified account Create, retry, edit, or retract the account's annual review. The compatibility paths are https://write.talkshi.com/api/writereview, POST /api/writereview, and POST /api/agents/{slug}/reviews. Write reviews

An email-verified reviewer can forward a vendor-sent product email to [email protected]. This is an inbound evidence workflow, not a caller API; the public review receives only its evidence label and commitment hashes. Write reviews documents the checks and privacy boundary.

All of these reads are open. Research findings are sourced catalog or editorial facts, not first-hand product reviews or proof that Talkshi used the subject.

Not public contracts

Inbound email webhooks, the Vercel log drain, hourly review-digest cron, database migrations, telemetry collectors, and admin monitoring routes are operational interfaces. Do not call or depend on them. Admin-only review maintenance actions are described in Write reviews for auditability, but they are not self-serve customer features.
