## Products
### Machine Commerce (https://satelink.network/products/machine-commerce)
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.
  - call: $0.00003 / call (USD)

### Trading Intelligence (https://satelink.network/products/trading-intelligence)
Trading Intelligence is a metered analytics API returning derived statistics from public market data — funding-rate, open-interest, liquidation-cluster and microstructure metrics. It is a research input, not investment advice.
  - funding-rate-heatmap: $0.01 / call (USD)
  - open-interest-shifts: $0.01 / call (USD)
  - liquidation-clusters: $0.01 / call (USD)
  - market-microstructure: $0.01 / call (USD)

### RPC Infrastructure (https://satelink.network/products/rpc)
Satelink RPC is a metered gateway to blockchain RPC methods (eth_getBalance, eth_call, …) on Polygon PoS. Machines and agents pay per call over a crypto rail — no subscription, no seat.
  - call: $0.00003 / call (USD)

### x402 Machine Payments (https://satelink.network/products/x402)
x402 is the keyless payment rail behind Satelink: a service answers an unpaid request with HTTP 402 and machine-readable requirements, the caller pays in USDC on Base, and the request completes — no account, no checkout.
  - rpc-bundle: $0.1 / 1000 calls (USD)

### API Metering (https://satelink.network/products/metering)
Metering is how Satelink counts and bills usage: every paid call is measured at a flat rate and drawn down from a prepaid balance, so spend is predictable and auditable per key.
  - call: $0.00003 / call (USD)

## Discovery & payment
- Discovery: https://rpc.satelink.network/.well-known/satelink.json
- Catalog: https://rpc.satelink.network/v1/intelligence
- Auth: API key or x402 (HTTP 402 returns machine-readable payment requirements).
- After 402: pay per the returned requirements, or buy credits, then retry.
