Satelink

Machine Commerce

The full discover → pay → call → settle loop for autonomous buyers.

Machine commerce is software paying software for services. Satelink is the infrastructure a machine uses to discover a priced API, pay for it without a human, call it, and settle the payment on-chain.

Discover without a signup

Agents read a public JSON catalog and machine-readable pricing before they ever authenticate.

Pay without a human

A 402 response quotes the price; the machine pays with x402, a USDT deposit, or a prepaid balance.

Settle transparently

Revenue aggregates per epoch and settles on-chain to a verifiable Polygon vault.

Frequently asked

About the offering

What is machine commerce?

It is software buying services from other software: a machine discovers a priced API, pays for it programmatically, calls it, and the payment settles on-chain — no human in the loop.

Do I need an account to start?

No. Discovery and pricing are public JSON. You need a key or an x402 wallet only when you make a paid call.

Trust and safety

What stops an agent from paying a price that isn't real?

The price is quoted by the service in a signed 402 response, per-key spending limits apply, and every settled call produces an on-chain-verifiable receipt.
