Frequently asked questions about Blockchain gas price

How much does a blockchain gas price API call cost?

Endpoints listed for crypto.gas_price on EntRoute are priced from $0.001 to $0.01 per call. Payment is per request — there is no subscription, account or API key. Prices shown are read from each endpoint's live 402 response, not from a provider-supplied catalogue.

How do AI agents pay for blockchain gas price endpoints?

Via the x402 protocol. The agent calls the endpoint, receives an HTTP 402 Payment Required response describing the price and recipient, signs a stablecoin payment (USDC on Base), and retries the request with proof of payment. The whole exchange takes seconds and needs no human approval.

How many providers offer blockchain gas price?

10+ endpoints are currently listed for crypto.gas_price across 6 providers. That number moves as endpoints are added and as failing ones are demoted.

Are these blockchain gas price endpoints verified?

Each one is probed every 10 minutes to confirm it still returns a well-formed 402 challenge on a payable network. Endpoints whose 7-day success rate drops below 50% are moved out of the ranked list into fallbacks with an explicit exclusion reason, so an agent can decide whether to retry them.
