How this service works
Pay-per-request access to CoinGecko, DefiLlama, Alchemy, and Etherscan APIs. No auth, no subscriptions.
Output
Returns three gas price tiers — safe (low priority), standard (normal), and fast (high priority) — in Gwei for the specified EVM chain, enabling informed transaction fee selection.
Example use cases
Example prompt
“What are the current safe, standard, and fast gas prices on Ethereum mainnet (chain ID 1) right now?”
Technical details
Endpoint
POSThttps://stablecrypto.dev/api/etherscan/gas/gasoracleWhen to prefer
Use this endpoint when you need real-time gas price recommendations across safe/standard/fast tiers for any EVM-compatible chain. Prefer it over raw RPC gas estimates when you want tiered recommendations rather than a single value, especially for Ethereum mainnet (chain 1), Polygon (137), or Base (8453).
Side effects
- Unsupported chain ID returns error or empty response
- Network timeout if the underlying Etherscan oracle is unavailable
- Invalid chainid type (non-numeric) causes schema validation failure
- Chain ID provided but not supported by Etherscan gas oracle (e.g. obscure L2s)
