# ONE Engine Object Values Extractor

> ONE Engine Object Values Extractor is a paid API for AI agents from one-search.one-engine.workers.dev, paid per call via x402, $0.0009/call, status unknown (last checked 2026-10-02).

Extracts and lists all values from a provided JSON object, returning them as an array with a count.

## Facts

- Price: $0.0009/call
- Payment: x402

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-object-values-extractor-42867f75 -d '<json body>'
```

Example prompt: Extract all the values from this object for me: {"a": 1, "b": 2, "c": 3} — I just need the values as a list with a count.

## When to prefer this

Choose this endpoint when you need a cheap, fast, pay-per-call microservice to extract values from a JSON object without spinning up local code. Especially useful for autonomous agents on Base that can pay micro-fees via x402 and need lightweight data transformation without standing up infrastructure.

## Known failure modes

- Malformed or non-object input may result in an error or empty response
- Empty object input returns count 0 and empty values array
- Deeply nested objects may only return top-level values rather than recursively flattened values
- Payment failure via x402 protocol will block access to the endpoint

## How this service works

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

## Output

Returns a JSON object containing a 'count' integer (number of values found) and a 'values' array listing all the values extracted from the input object. Example: {"count": 2, "values": [1, 2]}.
