Verdicts

Plaid Identity Verification

Plaid Identity Verification has four typed endpoints in Plaid's public OpenAPI file, an idempotent create, a backend-only flow for data source checks and frequent changelog entries. Prices appear only after applying for Production, the secret has no scopes, and the rate-limit and error pages are disallowed to crawlers.

Vouched

Vouched publishes per-transaction prices from $0.75 with a $300 monthly minimum and a 14-day trial, and its docs carry llms.txt, OpenAPI fragments and filterable job search. Rate limits have no number, there is no idempotency key, server SDK or security.txt, and the API status page shows a 70-minute rise in rejections on 1 October 2026.

Before you call either

Plaid Identity Verification

  1. Pass is_idempotent: true to /identity_verification/create so a retry returns the existing session
  2. Use the backend-only flow (data source template, gave_consent: true) when you already hold the user's details. Documents and selfies need the person in Link
  3. Wait for the STATUS_UPDATED webhook or poll /identity_verification/get. Link's onSuccess doesn't mean the user passed
  4. Don't issue retries casually. Each retry is a new session billed again
  5. Enable Sandbox for Identity Verification on the Dashboard Products page before the first call

Vouched

  1. Use the private key in X-API-Key against verify.vouched.id or verify.eu.vouched.id, matching the account's region
  2. Check Find Jobs before resubmitting. There is no idempotency key and each job is billed
  3. Pass withPhotos=false and select fields on Find Jobs to keep responses small
  4. In a test account, use the name test pass for a clean result and any other name for a failure
  5. Back off on 429. All endpoints share one limit and no figure is published
