Transform any SQLite DB into a pay-per-query API with x402 micro-payments - Auto schema detection + simulation & real testnet

Code examples for consuming L402 APIs with Lightning payments

Reproducible black-box benchmark: real x402 implementations (Payload kit, x402-hono, @x402/express) tested against 7 production failure modes. Every number measured.

Monetize any Express API with zero-gas USDC micropayments via x402 protocol (Base + SKALE)

Hosted Remote MCP and stdio server for SynapseNetwork agent payments, paid API discovery, invocation receipts, and ChatGPT/Claude-compatible MCP clients.

Validate an x402 payment manifest (/.well-known/x402): required endpoint fields, sane values, optional live 402 probe. Zero-dependency Node.js CLI by Payload.

Starter templates for accepting and paying x402 payments with the official SDKs: Express, Hono, Next.js, FastAPI, and Node and Python clients.

Minimal working example of a pay-per-call API for AI agents using x402 (Express, USDC on Base). Fork it to monetize your API — no accounts, no keys.

AiFinPay agent skills: pay for x402-gated APIs as an agent (aifinpay) and charge agents for your API as a merchant (aifinpay-merchant).
