# ONE Engine JSON Key Omitter

> ONE Engine JSON Key Omitter is a paid API for AI agents from one-search.one-engine.workers.dev, paid per call via x402, $0.0011/call, status unknown (last checked 2026-10-02).

Removes specified keys from a JSON object and returns the filtered result

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 one-engine-json-key-omitter-d2d49d54 -d '<json body>'
```

Example prompt: Strip the keys 'password' and 'secret_token' from this JSON object: {"username": "alice", "password": "hunter2", "secret_token": "abc123", "email": "alice@example.com"}.

## When to prefer this

Use this endpoint when you need a lightweight, pay-per-call utility to strip specific top-level keys from a JSON object without standing up custom transformation logic. Ideal for autonomous agents that need a cheap (~$0.001), fast JSON pruning step in a pipeline — e.g., sanitizing payloads, removing sensitive fields, or slimming objects before forwarding downstream. Prefer this over building a custom filter when cost, simplicity, and x402/Base payment compatibility matter.

## Known failure modes

- Missing 'keys' array — returns error or unfiltered object
- Missing 'value' object — no object to filter
- Attempting to omit nested keys (dot notation) may not be supported
- Payment failure via x402 if wallet has insufficient USDC on Base

## How this service works

Low-cost pay-per-call utility APIs for autonomous agents using x402 on Base.

## Output

A JSON object containing the original object's key-value pairs with the specified keys removed, returned under a 'value' field.
