Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability chainray-gas-fee-stream-decc18b0
```

Example prompt: What are the current gas fees on Base right now? Use ChainRay to stream the latest gas price for the Base network.

## When to prefer this

Use this endpoint when an AI agent needs real-time gas fee data for a specific blockchain (e.g. Base, Ethereum, Polygon) to estimate transaction costs, optimize transaction timing, or monitor gas price trends. Prefer this over static or cached sources when up-to-the-moment accuracy is required.

## Known failure modes

- Unsupported or unrecognized chain identifier returns an error or empty response
- Missing chain parameter may default to a specific chain or return an error
- Payment not processed (x402 payment required, returns 402 if unpaid)
- Network timeout or upstream blockchain node unavailability
- Rate limiting if too many requests in a short period

## 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 real-time gas fee data for the specified blockchain network, including current gas prices or fee estimates relevant to transacting on that chain.
