How this service works
Signal Nodus: year-over-year diffs of SEC filing sections, pinned to accession numbers. The diff is the product; raw data is the on-ramp.
Output
A JSON object containing the chain name (e.g. 'base'), the block number at which the gas price was sampled (atBlock), and the gas price in Gwei (gasPriceGwei) as a float.
Example use cases
Pre-transaction gas cost check
“Before I submit this transaction on Base, can you check what the gas price is right now so I can estimate my fees?”
Historical gas price audit
“What was the gas price on Base at block 50113122? I need it for a cost reconciliation report.”
Multi-chain gas monitoring
“Can you pull the current gas price on Base and tell me if it's under 0.01 Gwei so I know whether to proceed with my batch of transactions?”
Technical details
Endpoint
GEThttps://api.signalnodus.ai/v1/evm/gas?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a lightweight, pay-per-call gas price lookup pinned to a specific block on an EVM chain (especially Base), without committing to a subscription or running your own node. Particularly useful for agents that need occasional gas estimates for transaction cost calculations or historical audits.
Side effects
- Invalid or unsupported chain identifier returns an error
- Requested block number is in the future or not yet finalized
- Network connectivity issues to the EVM node return a timeout or 503
- Malformed request missing required parameters returns a 400 bad request
- Payment not received (x402) results in a 402 Payment Required response
