Each visit mints a fresh verification under the rial. tenant (`tnt_rial`) tagged `originChannel='wa'` so the WA-completion worker delivers the verdict to the configured trial phone number once the user uploads a photo. **Rate-limited per IP** — in-memory limiter at 1000 req/h. Excess returns 429 with `Retry-After`. **No auth, no body required** — `source` is an optional free-text tag (e.g. `"qr_v2"`, `"agent-smoke"`) recorded on the verification's `metadata` for downstream analytics. ## OpenAPI ````yaml /api-reference/openapi.json post /v1/public/trial/start openapi: 3.1.0 info: title: rial-platform — Verifications API version: 0.1.0 description: |- # rial-platform — Verifications API HTTP control plane for the rial-platform verifications-service: creating verifications, capturing media against them, finalising cases for batch analysis, and the operator-facing dashboard. ## Audience - **Tenants** integrating rial into a claims / verification flow — use the operator-issued API key and call `POST /v1/verifications`, then send the returned `capture_url` to your end-user. - **The dashboard SPA** (`app.get-rial.com`) — same surface, authenticated via the `rial_session` cookie. - **The WhatsApp bot (rialclaw)** — signs requests with HMAC (`X-Bot-Auth`), carries the target tenant in the body. - **End-user browsers** capturing photos against a fresh verification — authenticated by possession of the path `:token` alone (the token IS the credential, see ADR-0002). ## Auth modes - `cookieSession` — `rial_session` cookie set by Google OAuth at `/v1/auth/google/callback`. Dashboard browsers. - `bearerApiKey` — `Authorization: Bearer pk_live_<…>` API key, tenant-scoped. Server-to-server integrations. - `captureToken` — possession of the verification id (`vfy_…`) in the URL path authenticates the SPA capture flow. Same trust model as Stripe payment intent client_secret. - `botHmac` — `X-Bot-Auth: ` from the WhatsApp bot. ## State machine A verification's status: `pending` → `partially_captured` → `completed` | `expired` | `failed`. State transitions emit domain events on the internal EventBridge bus; webhook events are translated from those and delivered to the tenant's configured `webhook_url` (HMAC-signed via the per-tenant `webhook-signing` secret). `pending`/`partially_captured` can also side-branch to `abandoned` — reported by the capture screen via `POST /v1/verifications/:token/progress` when the end user leaves before finishing. It is not terminal: a later capture resurrects the row to `partially_captured` like any other, and no webhook event fires for the transition. ## Conventions - Wire format is **snake_case JSON** in both directions; the service maps to camelCase internally. - Errors are `{error: {code, message, fields?}}` — `code` is the stable string SDKs branch on; `message` is human-readable English; `fields` is present only on `invalid_request` validation failures. - IDs are ULIDs with type prefixes: `vfy_`, `cap_`, `tnt_`, `walotp_`, `mlk_`. - Pagination is opaque-cursor: client passes back whatever `next_cursor` the previous page returned; absent means done. ## Out of scope here - Webhook payloads delivered to tenant URLs — those are documented separately under `docs/webhook-events.md`. This spec covers only the inbound HTTP surface, not the outbound HTTP rial → tenant calls. - Internal EventBridge events on the `rial-platform-events` bus (`verification.created`, `verification.case.completed`, …) — consumer-internal, not part of the public contract. contact: name: rial-platform team url: https://github.com/Rial-ventures-Inc/rial-platform license: name: UNLICENSED — proprietary, internal use only servers: - url: https://platform-staging.get-rial.com description: Staging (safe to hit; ANALYSIS=stub, CASE_ANALYSIS=gemini-case) - url: https://platform.get-rial.com description: Production (live tenant traffic; do not test against) security: [] tags: - name: Verifications description: >- Create, fetch, list, and finalize verifications.
