How this service works
Verifik AI — x402 KYC & KYB for autonomous agents, with deep LATAM coverage: national IDs, companies, vehicles, sanctions, and regional registries. Pay per validation, no subscription lock-in.
Output
Returns a JSON object containing a liveness determination (live/spoof), confidence or score data, and a cryptographic signature for tamper-proof auditability, per Verifik's standard response envelope with 'data' and 'signature' fields.
Example use cases
Example prompt
“Run a liveness check on this selfie image I captured on iOS — I need to confirm it's a real live person and not a photo or deepfake before proceeding with KYC verification.”
Technical details
Endpoint
POSThttps://ai.verifik.co/api/face-recognition/liveness?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a pay-per-use, no-subscription liveness check integrated into an autonomous agent KYC flow, especially for LATAM user bases. Prefer it over subscription-based biometric APIs when transaction volume is unpredictable and cost control per validation matters. Also ideal when you need a cryptographically signed response for audit trails.
Side effects
- Missing required 'os' or 'image' fields returns 400 Bad Request
- Image not parseable or unsupported format causes validation error
- Low-quality or blurry image may result in inconclusive liveness determination
- Payment not attached or insufficient USDC triggers x402 Payment Required
- Network timeout if image payload is too large
- Spoof detected returns liveness=false rather than an error
