These are observations, not accusations. A band of LOW, MEDIUM or HIGH describes how much of what we check we were able to confirm — it is not a judgement about the operator of an endpoint. Every signal, its weight and its rationale are published on the methodology page, and any operator can claim an endpoint, correct a fact or opt out.

Compare x402 blockchain data APIs

x402 endpoints that read a chain for you — balances, transactions, gas, wallets and RPC — compared on price per call, network and observed terms.

Up to 8 https URLs, comma separated. Compare reads what has already been observed — it does not fetch on demand. To have a new endpoint looked at, use the inspector.

Sorted by price.

Empty cells are not zeros. Each one says which state it is in — not in our index, not probed yet, no x402 challenge served, or did not answer.

What this table does and does not say

  • Availability and latency are not shown here. They are aggregates over the sampled probe dataset and are read one endpoint at a time, which is what the history page does — this page reads the index and makes no outbound request. Estimating them from the probe records kept in the database instead would over-report failure, because routine successful probes are deliberately not kept.
  • Usage figures on this page are published by the facilitator that lists the endpoint (coinbase-cdp), not measured by us. They are shown because they are better data than anything we can collect — and attributed because they are somebody else's.
