Which one, for what

Entrust Identity Verification (formerly Onfido) B

Best for A company already contracted with Entrust that wants an agent to create applicants, start workflow runs and read reports through typed libraries and a public spec.

Ahead on

  • Agent ergonomics, 65 against 56
  • Payments & pricing, 20 against 10
  • Transparency & trust, 70 against 61

Watch for

entrust.com answered 403 to every request, so the terms, privacy notice, pricing page and security.txt weren't read

Middesk C

Best for An agent onboarding or re-checking US businesses for a bank, lender or marketplace that already holds a Middesk contract, with registry, TIN, sanctions and lien data in one object.

Ahead on

  • Maintenance & community, 64 against 58

Also in its favour

  • A hosted endpoint, with nothing to install

Watch for

No public price. Fees are set in an order form, and every docs page ends with a prompt to contact sales

Verdicts

Entrust Identity Verification (formerly Onfido)

The v3.6 API has a public MIT OpenAPI file, server libraries in five languages, OAuth client credentials with scopes and an 18-month deprecation notice. Entrust's own site answered 403, so terms, privacy notice, pricing and security.txt weren't read. There is no idempotency key, and live tokens need a Dashboard account with billing details.

Middesk

A public OpenAPI 3.1 contract for 87 operations, llms.txt, Markdown docs and a dated weekly changelog make the REST API readable to an agent, and OAuth has a read-only scope. Access is sales-led. No price, self-serve signup or official SDK was found, and the hosted MCP server rejects sandbox keys.

Before you call either

Entrust Identity Verification (formerly Onfido)

  1. Use the regional host for the account (api.eu, api.us or api.ca.onfido.com/v3.6). v3.6 has no default region
  2. Prefer an OAuth client with only the scopes the task needs over a live API token, and refresh the 60-minute access token
  3. Stay under 400 requests a minute live and 120 in sandbox, and back off on a 429 rate_limit error
  4. Check before retrying a POST. There is no idempotency key, so a retry can create a second applicant or check
  5. Treat webhook events as duplicates or out of order, and verify X-SHA2-Signature over the raw body

Middesk

  1. Match the key to the host. mk_test keys work only at https://api-sandbox.middesk.com/v1 and mk_live keys only at https://api.middesk.com/v1
  2. Name the orders on POST /v1/businesses. Omitting them places a verification order plus every package the account runs automatically, all billed
  3. Send address_line1 and address_line2. The API ignores address_line_1 without an error
  4. A 201 means the business was created, not verified. Wait for the business.updated webhook or poll until status leaves pending
  5. Stay under 20 requests a second per account, and in sandbox wait the seconds in Retry-After after a 429 on business creation
