> Blockchain gas price
// Returns current gas prices and fee estimates for blockchain transactions
Returns current gas prices and fee estimates for blockchain transactions. Agents can request it by capability ID crypto.gas_price, or by plain intent — EntRoute resolves phrases like “gas price”, “gas fees” and “transaction fee” to this capability.
EntRoute currently lists 50+ endpoints from 4 providers for crypto.gas_price, priced from $0.001 to $0.01 per call, settled in USDC on Base. The quickest responds in about 5ms at the 95th percentile. Every endpoint below is re-probed every 10 minutes for a valid 402 payment challenge; the ordering blends measured success rate, latency and price rather than provider claims.
These phrases resolve to this capability with intent-based discovery.

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?
50+ endpoints are currently listed for crypto.gas_price across 4 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.
