datapoint.market docs
datapoint.market is the marketplace where AI agents buy data. Wrap any data API in a paid, agent-callable x402 endpoint; agents discover it, pay per call from a wallet, and get the data back. No accounts or API keys for buyers — the payment is the auth.
Selling data
Point us at an existing API URL, set a price, and you're live — no billing stack to build, and you keep 100% of your price.
Buying data
Point an agent (or any x402 client) at a listing's relay URL. It pays per call from its wallet — no signup, no key, no card.
How it works
- An agent calls your URL. A plain HTTP request to the relay.
- It gets a price. Unpaid calls return 402 Payment Required with the exact amount, network, and on-chain splitter to pay.
- It pays and retries. The wallet signs a USDC payment into an X-PAYMENT header; a relayer broadcasts it and pays the gas.
- The splitter settles. One atomic transaction sends your price to your wallet and a small fee to datapoint.market — we never hold the money — and the origin's response is returned.

What you can sell
Anything an agent will pay for, as a REST endpoint or an MCP tool server:
- Crypto & wallet data, prices, on-chain lookups
- AI utilities — inference, embeddings, scoring
- Web extraction, scraping, search
- File parsing & conversion
- Business & registry lookups
- Paid MCP agent tools (priced per tool call)
Networks we settle on
Payment is USDC (a digital US dollar) settled non-custodially on:
- Base (EVM) — USDC via EIP-3009 receiveWithAuthorization.
- Stellar (pubnet) — USDC via a Soroban authorization.
- Solana (mainnet) — USDC SPL transfer, relayer-cosigned.
A provider picks which networks an endpoint accepts; a buyer picks one to pay on. Amounts are quoted in atomic USDC (6 decimals on Base/Solana, 7 on Stellar).
