## 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 signaldesk-ai-json-omit-keys-fb7ba7f0 -d '<json body>'
```

Example prompt: Take this JSON object and remove the keys 'password', 'ssn', and 'creditCard' from it before I send it to the frontend.

## When to prefer this

Choose this endpoint when you need a simple, stateless, pay-per-call JSON key removal operation without setting up local transformation logic. It is ideal for agents that need to sanitize or filter JSON on the fly within a workflow, especially when already operating in an x402 micropayment context.

## Known failure modes

- Invalid or non-object 'data' input returns an error
- Keys array exceeds 100 items limit causes rejection
- Non-string values in keys array may cause validation failure
- Payment not included or insufficient USDC (x402) results in 402 response
- Malformed JSON body returns parse error

## How this service works

Evidence-backed autonomous AI jobs and paid data tools. Queue/D1/cron run outside the chat; free quotas and bounded execution apply.

## Output

A JSON object identical to the input but with the specified keys removed. The response wraps the result in a 'data' field, e.g. {"data": {"a": 1}}.
