CallerAPI

Phone-Based KYC and Identity Verification

For lightweight identity verification flows, call /api/v1/kyc with the phone number to retrieve associated identity signals such as ported date, porting history, and online presence. This is much cheaper than document-based KYC and is well-suited to first-line fraud screening before escalating high-risk users to a full document verification provider.

Daily Spam Report Webhook

Subscribe to daily spam reports by POSTing to /api/v1/webhooks/subscribe and receive batches of newly reported numbers at the configured URL. Use /api/v1/webhooks/test to verify reachability and /api/v1/webhooks/dispatch to manually trigger a redelivery during incident response. The reports feed your block lists without polling.

Bulk Contact Enrichment

Upload a batch of contacts to /api/v1/upload/contacts to enrich them in one request rather than calling spam-score for each number. The same Upload tag also exposes /api/v1/upload/spam-reports for sending your own user-reported spam back into the shared dataset, which both improves the global signal and ensures your reports are reflected in future scores.

AI Agent Phone Intelligence via Jentic

Through Jentic, an AI agent searches for an intent like 'check the spam score of a phone number' and is returned the CallerAPI spam-score operation along with its input schema. The agent calls the operation without ever holding the raw x-api-key value, and can chain into KYC, ported-date, or online-presence checks based on the spam score response. Setup time is under an hour rather than several days of direct integration.
