Verdicts

ComplyAdvantage

The Mesh API has a public OpenAPI 3.0.3 spec with 165 described operations, per-credential permissions and audit log endpoints, which suits an agent screening customers and working alerts. No status page, changelog, SDK, service agreement or subprocessor list was found in public, and access starts with a paid plan bought by a person.

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.

Before you call either

ComplyAdvantage

  1. Exchange the access key and secret at POST /v3/token for a bearer token. It lasts 24 hours and can't be refreshed, so request a new one before expiry
  2. Ask for a credential with only the permissions the task needs. Permissions can't be edited later, and each reference page names the ones a call requires
  3. Create a screening configuration first and keep its configuration_identifier. Creating and screening a customer needs it
  4. Give each customer a unique external identifier. A concurrent request for the same identifier returns 409 with a pointer to the first workflow
  5. Read Ratelimit-Remaining and Ratelimit-Reset on every response. A 429 body is only API rate limit exceeded

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
