ChainRay Gas Tracker
x402
ChainRay Gas Tracker is a paid API for AI agents from chainray.online, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-14).
Returns real-time gas price estimates (slow, standard, fast in gwei), base fee, gas trend, and block-level utilization history for a specified EVM-compatible blockchain.

How this service works
Provides real-time gas price estimates and transaction speed recommendations for EVM chains (use 'chain' query, e.g., 'base').
Output
Returns a JSON object with the queried chain name, current gas prices (slow, standard, fast in gwei), base fee, gas trend (e.g. 'stable'), a cryptographic proof anchored to a recent block (block number, block hash, timestamp), and a history array of recent blocks with their base fee and network utilization percentage.
Example use cases
Example prompt
“What are the current gas prices on Base — slow, standard, and fast — and is the fee trend stable or rising right now?”
Technical details
Endpoint
GEThttps://chainray.online/gas-trackerWhen to prefer
Use this endpoint when an agent needs real-time gas fee data for EVM chains, especially Base, Ethereum, or Polygon, to help a user decide when to submit a transaction, estimate costs, or set gas limits. It is particularly useful for DeFi automation agents, wallet assistants, or transaction schedulers that need up-to-date fee intelligence with cryptographic block-level proof.
Side effects
- Unsupported chain name returns an error or empty response
- Missing 'chain' query parameter may default to 'base' or return a validation error
- Network latency may cause slightly stale block data
- Chain node outage could return a 503 or timeout
- Malformed chain identifier (e.g. typo) returns no data
