## Which one, for what

### 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.

Ahead on:
- Agent ergonomics, 56 against 46

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

### Socure RiskOS (B)

Good for: A company in the United States that wants one decision from combined KYC, document, fraud and watchlist checks through a single evaluation call.

Ahead on:
- Payments & pricing, 35 against 10
- Maintenance & community, 75 against 64
- Transparency & trust, 68 against 61

Watch for: No service agreement or API terms are published. The only terms pages are website terms of use and end-user terms for document capture

## Verdicts

**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.

**Socure RiskOS.** A public OpenAPI file, llms.txt, 15 documented error codes and dated release notes cover a ten-operation REST API, and Socure Launch publishes prices from $0.80 an evaluation with a free sandbox. API keys carry no scopes, no idempotency header is defined, no service terms are published, and production stays at zero requests until Socure activates it.

## Before you call either

### 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

### Socure RiskOS

1. Send `Authorization: Bearer <key>` to `https://riskos.sandbox.socure.com/api/evaluation` for tests and `https://riskos.socure.com/api/evaluation` for live checks. The two environments use separate keys.
2. Use dummy data only in the sandbox. It returns predefined results, connects to no live data source and expects the documented test values.
3. Store the `eval_id` from every `POST /api/evaluation` response. No list or search endpoint exists to find it later.
4. On 429 wait the seconds given in `X-Retry-After`. Do not blindly resend a failed `POST /api/evaluation`, because no idempotency header is documented and Launch bills each initiated evaluation.
5. The MCP server at `https://mcp.riskos.socure.com/sandbox` reads docs, workflows and webhooks with its own MCP Server Key. It cannot run evaluations or read results.
