How this service works
Market data and agent tools (web-read, email-verify, token-check) for AI agents, paid per-call via x402 (USDC on Base). Free index at /, free spec here.
Output
A JSON object with gas data for Ethereum mainnet and Base: next base fee in gwei, estimated USD cost of an ERC-20 transfer for each network, and the current ETH/USD exchange rate used for calculations.
Example use cases
Pre-transaction gas cost check
“Before I send these USDC tokens, can you check what gas fees look like on Base and Ethereum right now so I can pick the cheaper network?”
DeFi trade timing decision
“Is now a good time to execute my on-chain swap? What's the current Ethereum gas fee in gwei and how much would the transaction cost me in USD?”
Agent wallet cost estimation
“I need to estimate how much my agent will spend in gas fees per ERC-20 transfer on the Base network — can you pull the current gas data?”
Technical details
Endpoint
GEThttps://orchard-data.letom1176.workers.dev/api/gas?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent needs real-time gas fee awareness before executing or recommending blockchain transactions, particularly on Ethereum mainnet or Base. It is ideal for cost estimation workflows, timing optimizations, and multi-network comparisons in a single call. Prefer this over on-chain RPC calls when you want a pre-computed USD cost estimate without running your own node.
Side effects
- Upstream gas oracle unavailable — endpoint may return 5xx or stale data
- Payment not submitted or insufficient USDC — 402 Payment Required response
- Rate limiting if too many rapid calls — possible 429 response
- Network connectivity issues to Cloudflare Worker — timeout or 503
