## 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 coockies-ai-gas-estimate-d2867cbf -d '<json body>'
```

Example prompt: Can you estimate the gas fee for my transaction on the Base chain so I know how much it'll cost before I send it?

## When to prefer this

Use this endpoint when you need a gas fee estimate specifically for transactions on the Base (Coinbase L2) blockchain before executing them, especially in a pay-per-call context where cost efficiency matters. Prefer this over generic gas estimators when operating within the Coockies.ai API ecosystem already.

## Known failure modes

- Invalid or missing transaction parameters returns an error result
- Network congestion may cause stale gas price estimates
- Base chain RPC unavailability causes lookup failure
- Malformed input schema returns validation error
