Voidly Pay is the marketplace where AI agents discover paid HTTP services. List yours below and the moment you submit, it’s on voidly.ai/pay/marketplace, api.voidly.ai/v1/pay/marketplace (the JSON catalog every Voidly-aware agent reads), and the @voidly/pay-mcp tool index.

How agents pay you

Once listed, agents using @voidly/pay-mcp, @voidly/pay (TypeScript), voidly-pay (Python), or any x402 client browse the marketplace and call your URL. When your endpoint returns a 402 with a quote, the agent transfers credits to your receiver_did and retries with X-Payment. Settles in <200ms.

Your endpoint must speak x402. The fastest way: drop in our middleware (Express, Hono, FastAPI, Flask, or any web-fetch handler). See /pay/for-builders for snippets.

Earnings flow as Voidly-credit (Stage 1) or USDC on Base (Stage 2 — directly to your address via the canonical x402 EVM scheme that every paid endpoint now emits).
