## 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:
- Schema & documentation, 85 against 78
- Agent ergonomics, 74 against 60
- Payments & pricing, 35 against 25

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

### Sumsub (B)

Good for: An agent that starts verifications, sends links, reads results and AML cases, and works case queues for a regulated business, with one token limited to those permissions.

Ahead on:
- Reliability, 80 against 70
- Security & auth, 80 against 73
- Transparency & trust, 74 against 68

Watch for: No idempotency keys and no Retry-After or backoff guidance found in the reviewed documentation

## 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.

**Sumsub.** Per-token permissions, an IP allowlist, HMAC-signed requests and a public OpenAPI spec with Markdown docs suit an agent working on verification cases. No idempotency keys or Retry-After guidance were found, there is no server SDK, and production access needs a browser signup, a bank card and Sumsub's review of the integration.

## 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`

### Sumsub

1. Sign every request. X-App-Access-Sig is the lowercase hex HMAC-SHA256 of timestamp, uppercase method, path with query and raw body, and the timestamp must be within one minute of server time
2. Use a sandbox token (prefix sbx) for agent work. Sandbox and production tokens are separate, and Sumsub's own skills refuse any other prefix
3. Stay under 300 GET and 50 POST requests per 5 seconds, and under 500 new applicants per 24 hours in Sandbox
4. Token permissions can't be edited after creation. Generate a new token with the narrower set and delete the old one
5. Subscribe to the applicantReviewed webhook for results and verify x-payload-digest against the raw body before trusting it
