## 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 kiteendpoints-ai-gas-estimate-a52dd851 -d '<json body>'
```

Example prompt: Can you estimate how much gas this transaction will cost on the Base chain before I send it?

## When to prefer this

Use this endpoint when you need a quick gas fee estimate before committing to a blockchain transaction, especially on Base chain or EVM-compatible networks. Prefer this when building cost-aware Web3 agents that need to budget or time transactions optimally.

## Known failure modes

- Invalid or missing transaction parameters result in error response
- Network congestion may cause estimates to be stale by execution time
- Unsupported blockchain network returns error
- Malformed request body returns 400-level error
- Payment of 0.09 USDC not provided results in 402 Payment Required
