## Which one, for what

### ComplyAdvantage (D)

Good for: An agent that screens customers and companies against sanctions, politically exposed person and adverse media data, keeps them under monitoring and works the resulting alerts and cases.

Watch for: No public status page or incident history was found. `status.complyadvantage.com` does not resolve

### Didit (BB)

Good for: A team that wants document, liveness, screening and business registry checks from one API with public prices and no sales step, and an agent that has to set itself up.

Ahead on:
- Reliability, 80 against 42
- Schema & documentation, 88 against 82
- Security & auth, 76 against 68
- Payments & pricing, 60 against 10
- Maintenance & community, 82 against 28
- Transparency & trust, 63 against 50

Also in its favour:
- Agent-ready, a grade of BB or better
- Runs on your own machine
- Free to start without a card

Watch for: Three incidents marked major on status.didit.me from 22 July to 4 September 2026, each a partial outage of the core APIs traced to the primary database

## 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.

**Didit.** A self-serve verification API with public per-check prices, key registration by API, scoped keys and a 365-day audit log. The status page shows three incidents marked major between 22 July and 4 September 2026, each a partial outage of the core APIs, and the sub-processor list isn't public.

## 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`

### Didit

1. Register with `POST https://apx.didit.me/auth/v2/programmatic/register/`, then `verify-email` with the emailed 6-character code. Use a real inbox, because reserved test domains return 500.
2. Send the key as `x-api-key` to `https://verification.didit.me/v3/`. The JWT from registration works only on `apx.didit.me`.
3. Create a workflow before `POST /v3/session/`. `workflow_id` is the only required field, and an unfinished session with the same `vendor_data` is returned again.
4. Read results from webhooks and use `GET /v3/session/{sessionId}/decision/` for back-fill. Every per-feature result is a plural array.
5. The MCP server at `https://mcp.didit.me/mcp` takes OAuth sign-in only, never an API key. Approve `didit:verification` alone when the task doesn't change workflows or keys.
