Which one, for what

Persona B

Best for A company that already runs Persona and wants an agent to create inquiries from templates, read verification and report results, screen against watchlists and work review cases with a permission-limited key.

Ahead on

  • Security & auth, 73 against 61
  • Payments & pricing, 35 against 15

Also in its favour

  • A hosted endpoint, with nothing to install

Watch for

Production access needs Persona's approval and a 12-month plan from $250 a month, and API-only integration is limited to Enterprise plans

Plaid Identity Verification B

Best for US, Canadian and UK companies that want KYC with data source checks, documents and selfies, especially those already on Plaid or wanting Monitor screening in the same flow.

Ahead on

  • Schema & documentation, 91 against 85
  • Maintenance & community, 83 against 75
  • Transparency & trust, 77 against 68

Watch for

Verdicts

Persona

The REST API has a public OpenAPI 3.1 file, llms.txt, API keys with per-resource permissions, idempotency keys on every POST and a 60-day sandbox trial with no card. Production needs a business review and a 12-month plan from $250 a month. The status page lists 11 incidents since 10 July 2026, including 70 minutes of timeouts across all products.

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.

Before you call either

Persona

  1. Ask for a dedicated key limited to the permissions the task needs. A new key has every standard permission until it's limited
  2. Send Persona-Version on every call and an Idempotency-Key on every POST. A replayed key returns the first result, including a 500
  3. Treat redact calls as irreversible. They permanently delete personal data and cascade to downstream objects
  4. Stay under 300 requests a minute in production, read RateLimit-Remaining and Quota-Remaining, and back off on 429 because rejected requests still count
  5. Use fields and include to cut response size. Through MCP these parameters aren't exposed, and only 14 tools take filter

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
