Capabilities
See the SDK feature matrix for current support across every official implementation.
The TypeScript SDK includes SQL-backed stores and Cloudflare Workers storage and settlement. Use these adapters to share payment state across server instances.
Read typed operations, price offers, and JSON request schemas with listOperations. Discovery prices are advisory; the 402 Challenge remains authoritative.
Use Persona KYC to link a verified wallet and require an approved inquiry before settlement. Use email OTP to require a verified email address before payment, Link attestation to verify a buyer's Link token, or Link claims to request verified profile fields. Adapt an existing identity system with Identity.from. The identity guide covers client and server setup.
