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-760924c0
```

Example prompt: What's the best cross-chain swap route and total cost to bridge from Base to Ethereum right now — including bridge fees, gas, and slippage — using the ChainRay solver feed?

## When to prefer this

Use this endpoint when you need real-time cross-chain swap routing intelligence, including cost breakdown, slippage, gas estimates, and market competitiveness for a specific blockchain. Prefer this over generic gas fee endpoints when you need full solver-level intent routing data conforming to ERC-7683, not just gas prices.

## Known failure modes

- Invalid or unsupported chain identifier returns an error or empty route
- Network timeout if the solver feed is temporarily unavailable
- Missing required 'chain' query param may return default chain or error
- Stale data if block proof timestamp is significantly behind current time

## 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 a recommended cross-chain swap route (from/to chain and token), cost breakdown (bridge fee, gas costs from/to, expected slippage, total cost in USD), market conditions (competition level, gas trends, native token price, estimated time), a timing recommendation (e.g. execute_now), the intent standard used (ERC-7683), and a cryptographic block-level proof of data freshness.
