## 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-9ef1f9c3 -d '<json body>'
```

Example prompt: Before I submit this transaction on Base, can you give me a gas estimate so I know how much it'll cost?

## When to prefer this

Use this endpoint when you need a quick, pay-per-request gas estimate for Base chain transactions without maintaining a dedicated Web3 node connection. Particularly useful for lightweight agents that occasionally need gas cost data without integrating a full RPC provider.

## Known failure modes

- Invalid or missing transaction parameters may return a generic error or example response
- Upstream gas oracle unavailability may cause stale or fallback estimates
- Poorly specified transaction object may produce inaccurate estimates
- Schema is loosely defined so error responses may be indistinguishable from success responses

## How this service works

400+ paid API endpoints. Social media, AI, crypto, finance, weather, ecommerce, tools. Pay per request with USDC on Base chain.

## Output

Returns an estimated gas fee or cost object for a proposed transaction on the Base blockchain, including the estimated gas units and price that the agent can use to inform the user or gate further actions.
