How this service works
The most complete blockchain data and intelligence service for AI agents. 93 endpoints across 46 chains, from gas fees to DeFi analytics, with real-time streams, intent routing, and verifiable proofs. Pay-per-request via x402.
Output
Returns predicted gas fee data for the requested blockchain network, including current gas price estimates that an agent can use to decide whether to proceed with a transaction or optimize timing.
Example use cases
Example prompt
“What are the predicted gas fees on Base right now? I want to know if it's cheap enough to submit my transaction.”
Technical details
Endpoint
GEThttps://chainray.online/predict/gasWhen to prefer
Use this endpoint when an AI agent needs real-time or predicted gas fee data for a specific blockchain before submitting or recommending a transaction. It covers 46 chains including Base, Ethereum, and Polygon, making it ideal for multi-chain applications. Prefer this over generic RPC calls when you need prediction (not just current) data and want a simple pay-per-request model without subscription overhead.
Side effects
- Unsupported chain identifier returns an error or empty result
- Missing required chain parameter may return a default or error
- Payment failure (402) if x402 payment header is not included or USDC balance is insufficient
- Network timeout if the blockchain RPC is slow or unavailable
- Rate limiting if too many requests are sent in quick succession
