Head to head · Kyc identity · October 2026 research run
Jumio vs Sumsub
Sumsub scores 68.5 (B) on agent readiness against Jumio's 55 (C), and leads in 6 of 7 scored categories. Both do kyc identity.
Which one, for what
Jumio C
Good for An enterprise with a Jumio contract that wants document, selfie and liveness checks, watchlist screening and Latin American, Thai and Australian database checks behind OpenAPI-described endpoints.
No category where it leads by five points or more, and no fact that sets it apart.
Watch for
No public price, free tier or trial. OAuth2 and workflow keys are activated by a Jumio account manager
Sumsub B
Good for An agent that starts verifications, sends links, reads results and AML cases, and works case queues for a regulated business, with one token limited to those permissions.

Verdicts
Jumio
Five OpenAPI 3.0 files, an llms.txt index and OAuth2 clients limited to initiating or to retrieving and deleting make the API readable and containable. Access starts with an account manager, with no public price, trial or service agreement, and the status page shows four processing degradations and a 35-minute Singapore outage between 14 August and 2 October 2026.
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
Jumio
- Use the host for the tenant's region (amer-1, emea-1 or apac-1). Tokens come from auth.<region>.jumio.ai/oauth2/token with the client ID and secret as Basic credentials
- Reuse the bearer token for its 60 minutes. Token requests are limited to 10 a second and new transactions to 1 a second per tenant
- Send a User-Agent header on every call. The Account API marks it required
- Don't blindly retry POST /api/v1/accounts. Each call creates an account and a transaction, and no idempotency key exists
- Wait for the callback or poll the status endpoint until PROCESSED before retrieving. Jumio's retry schedule starts at 40 seconds and stops after 940
Sumsub
- 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
- Use a sandbox token (prefix sbx) for agent work. Sandbox and production tokens are separate, and Sumsub's own skills refuse any other prefix
- Stay under 300 GET and 50 POST requests per 5 seconds, and under 500 new applicants per 24 hours in Sandbox
- Token permissions can't be edited after creation. Generate a new token with the narrower set and delete the old one
- Subscribe to the applicantReviewed webhook for results and verify x-payload-digest against the raw body before trusting it
