How it works

Three things happen when your agent needs data.

The agent hits a paywall

Your agent requests premium data. The server responds with 402 Payment Required — price and wallet address in the response header.

HTTP/1.1 402 Payment Required
X-Payment-Amount: 0.01
X-Payment-Asset: USDC
X-Payment-Network: stellar:testnet

Instant payment

The agent signs a USDC transaction on Stellar. Fees under $0.00001. Settlement in under 5 seconds.

Data unlocked

Payment verified. The endpoint returns data with a full transaction receipt your agent can audit.

Pricing

Pay per action.
Not per month.

Every tool has a transparent, per-use price. No subscriptions, no credit packs, no minimums.
