## 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 73
- Schema & documentation, 88 against 82
- Agent ergonomics, 69 against 56
- Security & auth, 76 against 56
- Payments & pricing, 60 against 10
- Maintenance & community, 82 against 64

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

### Middesk (C)

Good for: An agent onboarding or re-checking US businesses for a bank, lender or marketplace that already holds a Middesk contract, with registry, TIN, sanctions and lien data in one object.

Watch for: No public price. Fees are set in an order form, and every docs page ends with a prompt to contact sales

## 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.

**Middesk.** A public OpenAPI 3.1 contract for 87 operations, llms.txt, Markdown docs and a dated weekly changelog make the REST API readable to an agent, and OAuth has a read-only scope. Access is sales-led. No price, self-serve signup or official SDK was found, and the hosted MCP server rejects sandbox keys.

## 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.

### Middesk

1. Match the key to the host. `mk_test` keys work only at https://api-sandbox.middesk.com/v1 and `mk_live` keys only at https://api.middesk.com/v1
2. Name the `orders` on `POST /v1/businesses`. Omitting them places a verification order plus every package the account runs automatically, all billed
3. Send `address_line1` and `address_line2`. The API ignores `address_line_1` without an error
4. A 201 means the business was created, not verified. Wait for the `business.updated` webhook or poll until `status` leaves `pending`
5. Stay under 20 requests a second per account, and in sandbox wait the seconds in `Retry-After` after a 429 on business creation
