## Which one, for what

### ComplyCube (B)

Good for: An agent that creates clients, uploads documents, starts document, identity and AML screening checks and reads results for a regulated business, with low entry cost ($99 a month) and a scripted sandbox.

Ahead on:
- Reliability, 84 against 73
- Payments & pricing, 27 against 10
- Maintenance & community, 74 against 64

Watch for: One API key per environment with no scopes. The docs say keys carry many privileges

### 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

**ComplyCube.** A sandbox with its own key and scripted outcomes, a public OpenAPI spec, Markdown docs and an audit log API suit an agent running verification checks. Each environment has one unscoped key, no idempotency keys were found, and the only published terms are undated and read as website terms.

**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

### ComplyCube

1. Send the key bare in the `Authorization` header, with no Bearer prefix. Keys start `test_` or `live_`
2. Create a client first, then documents or live photos for it, then `POST /v1/checks` with the client and upload IDs
3. Stay under 10 requests a second live and 5 in the sandbox. On 429, back off exponentially with jitter, starting at 30 seconds
4. A badly formed filter returns 200 with no results, so check filter names before trusting an empty list
5. Checks are asynchronous. Subscribe to webhooks, verify the `ComplyCube-Signature` HMAC-SHA256 header, and expect duplicate and out-of-order events

### 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
