## Which one, for what

### Persona (B)

Good 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)

Good 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: No public prices. Rates appear only after a Production application

## 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
