How this service works
What a Base transaction costs right now, with the RPC provider and trust level behind the number, so a caller can tell a credentialed reading from a degraded one before pricing a transaction.
Output
Returns a JSON object with a SUCCESS status, the Base network identifier, and a gasPrice object reflecting the current base gas fee, along with source provenance indicating where the observation originated.
Example use cases
Pre-transaction gas cost estimation
“Before I submit this onchain transaction on Base, what's the current gas fee so I can estimate the total cost?”
Gas spike alerting for DeFi agent
“Check the current Base gas fee and let me know if it's spiked above normal — I want to hold off on executing trades if gas is expensive right now.”
Onchain analytics gas data enrichment
“Pull the latest base gas fee observation from Base with its source provenance — I need it to enrich my transaction cost analytics dashboard.”
Technical details
Endpoint
GEThttps://api.m2msentinel.com/v1/gas/feesWhen to prefer
Use this endpoint when you need a real-time, provenance-tagged observation of the current Base network gas fee — particularly when you need to know not just the fee value but also the source of that observation for auditability or multi-source validation. Prefer this over generic RPC calls when operating in an agentic, pay-per-call context already using the x402 micropayment protocol on Base.
Side effects
- Network unavailability may return a non-SUCCESS status
- Gas fee data may be momentarily stale during high network congestion
- Missing or malformed response if the upstream Base RPC source is unreachable
- Payment failure (402) if the $0.005 USDC micropayment is not processed correctly via x402 protocol
