Verdicts

Didit

A self-serve verification API with public per-check prices, key registration by API, scoped keys and a 365-day audit log. The status page shows three incidents marked major between 22 July and 4 September 2026, each a partial outage of the core APIs, and the sub-processor list isn't public.

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

Didit

  1. Register with POST https://apx.didit.me/auth/v2/programmatic/register/, then verify-email with the emailed 6-character code. Use a real inbox, because reserved test domains return 500.
  2. Send the key as x-api-key to https://verification.didit.me/v3/. The JWT from registration works only on apx.didit.me.
  3. Create a workflow before POST /v3/session/. workflow_id is the only required field, and an unfinished session with the same vendor_data is returned again.
  4. Read results from webhooks and use GET /v3/session/{sessionId}/decision/ for back-fill. Every per-feature result is a plural array.
  5. The MCP server at https://mcp.didit.me/mcp takes OAuth sign-in only, never an API key. Approve didit:verification alone when the task doesn't change workflows or keys.

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
