## Which one, for what

### 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 70
- Payments & pricing, 60 against 35
- Maintenance & community, 82 against 75

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

### 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:
- Agent ergonomics, 74 against 69
- Transparency & trust, 68 against 63

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

## Verdicts

**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.

**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

### 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.

### 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`
