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-online-a909e152
```

Example prompt: What gas optimization strategies does ChainRay recommend for Base right now — I want to minimize my transaction costs on that chain.

## When to prefer this

Use this endpoint when you need actionable gas optimization recommendations for a specific blockchain (e.g., Base, Ethereum, Polygon) rather than raw historical gas data or predictions. Prefer this over sibling endpoints like /gas-history or /gas-prediction when you want prescriptive guidance on minimizing transaction costs rather than just data.

## Known failure modes

- Unsupported chain identifier returns error or empty result
- Missing chain parameter may default to a specific network or return an error
- Network timeout if blockchain data source is temporarily unavailable
- Rate limiting or payment failure if the x402 micropayment is not properly handled

## 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 gas optimization guidance for the specified blockchain network, including recommended strategies, optimal transaction timing, and fee-reduction techniques tailored to the chain's current gas conditions.
