How this service works
The most complete blockchain data and intelligence service for AI agents. 93 endpoints across 46 chains, from gas fees to DeFi analytics, with real-time streams, intent routing, and verifiable proofs. Pay-per-request via x402.
Output
Returns the average gas price for the requested blockchain network, likely including values in Gwei or native units, along with the chain identifier and timestamp of the measurement.
Example use cases
Example prompt
“What's the current average gas fee on Ethereum right now? I want to know if it's a good time to submit a transaction.”
Technical details
Endpoint
GEThttps://chainray.online/oracle/gas-avgWhen to prefer
Use this endpoint when an AI agent needs to check current average gas fees on a specific blockchain before submitting a transaction, estimating costs, or advising a user on timing. Prefer this over manual RPC calls when you need a normalized, multi-chain gas oracle with pay-per-request pricing and no subscription overhead.
Side effects
- Unsupported chain identifier returns an error or empty result
- Missing chain parameter may default to a single chain or return an error
- Payment of $0.005 USDC not received results in HTTP 402 rejection
- Network downtime or RPC issues may cause stale or unavailable gas data
- Invalid chain string returns a validation error
