## 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 x402-chain-intel-gas-price-predictor-ca5eeee3 -d '<json body>'
```

Example prompt: What's the predicted gas price on Ethereum mainnet for the next 5 blocks — I need to time a swap transaction and want the lowest-cost window?

## When to prefer this

Choose this endpoint when you need forward-looking gas price estimates rather than current spot prices, especially for latency-sensitive trading bots that need to pre-calculate transaction costs across multiple upcoming blocks. It is particularly suited for DeFi bots, arbitrage engines, and liquidation bots operating on EVM-compatible chains where gas cost directly affects trade profitability.

## Known failure modes

- Network not supported — returns 400 if the requested chain is unsupported
- Prediction horizon too far — returns 422 if block lookahead exceeds model capability
- Payment not received — returns 402 if USDC payment is missing or insufficient
- Model unavailability — returns 503 if the prediction model is temporarily offline
- Invalid request body — returns 400 for malformed JSON or missing required fields
