Verdicts

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.

Sumsub

Per-token permissions, an IP allowlist, HMAC-signed requests and a public OpenAPI spec with Markdown docs suit an agent working on verification cases. No idempotency keys or Retry-After guidance were found, there is no server SDK, and production access needs a browser signup, a bank card and Sumsub's review of the integration.

Before you call either

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.

Sumsub

  1. Sign every request. X-App-Access-Sig is the lowercase hex HMAC-SHA256 of timestamp, uppercase method, path with query and raw body, and the timestamp must be within one minute of server time
  2. Use a sandbox token (prefix sbx) for agent work. Sandbox and production tokens are separate, and Sumsub's own skills refuse any other prefix
  3. Stay under 300 GET and 50 POST requests per 5 seconds, and under 500 new applicants per 24 hours in Sandbox
  4. Token permissions can't be edited after creation. Generate a new token with the narrower set and delete the old one
  5. Subscribe to the applicantReviewed webhook for results and verify x-payload-digest against the raw body before trusting it
