How this service works
Crest · gas_oracle -- Fetch current gas prices across multiple EVM chains. Returns fast/standard/slow estimates in gwei for Base, Ethereum, Polygon, Arbitrum, and Optimism.
Output
Returns fast, standard, and slow gas price estimates in gwei for each of the supported EVM chains: Base, Ethereum, Polygon, Arbitrum, and Optimism. Useful for deciding optimal transaction timing and chain selection.
Example use cases
Example prompt
“What are the current gas prices on Ethereum, Base, and Arbitrum right now — give me the fast, standard, and slow estimates in gwei so I can decide when and where to send my transaction.”
Technical details
Endpoint
GEThttps://data.crestsystems.ai/data/gas?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a multi-chain gas price overview across major EVM networks in a single call. Prefer it over chain-specific RPC calls when you want normalized fast/standard/slow tiers without parsing raw mempool data yourself. Ideal for agents deciding which chain to use for a transaction or timing submissions for cost efficiency.
Side effects
- Upstream chain RPC unavailable — partial or empty results for affected chains
- Rate limiting or payment failure — HTTP 402 if payment not provided
- Network timeout — slow response if any chain's data feed is delayed
- Stale data — estimates may lag real-time mempool if cache is not refreshed
