Pay-Per-Call API Guide

Review pay-per-call API pricing, request identity, delivery verification and failure handling.

Pay-Per-Call API Guide is a 4-page PDF field guide. Usage pricing, request identity, delivery checks and failure handling.

• Define the billable unit: A request, record, token, second or successful response creates different incentives.

• Quote before execution: Return enough terms for the buyer to evaluate price, scope and expiry.

• Make retries idempotent: Network failures should not silently create duplicate charges or deliveries.

• Issue useful receipts: Correlate quote, payment, request, response and acceptance status.

Action checklist: Name the unit and included limits; Publish deterministic pricing; Use idempotency keys; Separate payment from acceptance; Document timeout and refund rules; Expose usage and receipt records.

This guide does not determine legal, tax, sanctions or money-transmission obligations.
