## Which one, for what

### Stripe Identity (BB)

Good for: A business already on Stripe that needs document and selfie checks or US SSN validation with published prices.

Ahead on:
- Schema & documentation, 94 against 78
- Agent ergonomics, 93 against 60
- Security & auth, 86 against 80
- Payments & pricing, 40 against 25
- Maintenance & community, 85 against 74
- Transparency & trust, 85 against 74

Also in its favour:
- Agent-ready, a grade of BB or better

Watch for: Document, selfie and US SSN checks only. No sanctions or watchlist screening and no business verification

### 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 62

Also in its favour:
- A hosted endpoint, with nothing to install

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

## Verdicts

**Stripe Identity.** Stripe Identity runs on the Stripe API, with a public OpenAPI spec, idempotency keys, restricted keys for sensitive fields and a redact endpoint. The product page lists £1.25 per document and selfie check, and the first 50 are free. It has no watchlist or business screening, and outside GB, JP and the US it is in public beta.

**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

### Stripe Identity

1. Send an Idempotency-Key based on your user reference when creating a VerificationSession, so a retry doesn't make a second session
2. Send the end user the session URL or client secret. The person completes the check, the agent can't. Links expire after 48 hours
3. Use a restricted key for `verified_outputs.dob` and `id_number`. Without an IP restriction it reads them only for 48 hours
4. Wait for `identity.verification_session.verified` or `requires_input` webhooks instead of polling
5. Treat `redact` as irreversible, and don't put personal data in metadata

### 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
