PipRail

● healthy javascript-typescript

Backendless, no-fee x402 SDK for AI agents across 28 chains in 10 families (every major EVM chain plus Solana, TON, Tron, NEAR, Sui, Aptos, Algorand, Stellar & XRPL). Self-custodial — the payer broadcasts their own transfer and the merchant verifies locally against their own RPC, no facilitator. Take payments (`requirePayment`) or make them (`PipRailClient`), with per-call/lifetime spend budgets and a `planPayment()` affordability + recipient-readiness preflight. ([npm](https://www.npmjs.com/package/@piprail/sdk))
