x402 chain data API alternatives for agents

Small on-chain reads have unusually broad payer reach. This page makes the gap explicit: Delx can inspect an API or x402 server, but it does not yet sell a live RPC read.

Honest read

Where Delx wins — and where it does not

Exact read: Delx does not expose block, balance, ENS, transaction or contract-state data today.
Adjacent route: Delx can audit whether an API or x402 server is reachable, documented and integration-ready; it cannot answer an RPC query on the buyer's behalf.
Launch gate: a commercial RPC credential, per-call cap, receipt/refund behavior and a live parity smoke are required before a public chain SKU.
