Satelink

RPC Infrastructure

Metered blockchain RPC that machines pay for per call.

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.

Pay per call

A flat per-call rate — no monthly minimum, no seat licence, no commitment.

Keyless with x402

On Polygon PoS

Standard JSON-RPC methods proxied to Polygon mainnet (chain 137).
