## 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 primeapi-tax-estimate-aea3166c -d '<json body>'

Example prompt: Can you estimate how much tax I'd owe on $85,000 in freelance income this year, factoring in that I'm a single filer in the US?

## When to prefer this

Use this endpoint when you need a quick, programmatic tax estimate without integrating a full tax software suite. Best for approximate tax liability calculations based on natural language financial queries, especially when no API key setup is desired and pay-per-call via USDC on Base is acceptable.

## Known failure modes

- Vague or ambiguous query returns generic or low-confidence estimates
- Missing jurisdiction or filing status may produce inaccurate results
- Highly complex tax scenarios may not be handled accurately
- Payment failure in USDC results in 402 error and no response
- Malformed input query returns 400 or error response
