## 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 survey-json-path-lookup-2633f6ef -d '<json body>'
```

Example prompt: From this JSON string '{"user":{"name":"Ada","age":30}}', look up the value at the path 'user.name' using the survey JSON path lookup.

## When to prefer this

Choose this endpoint when you need a simple, hosted dot-path JSON value lookup without writing code, especially within survey data processing workflows where JSON documents need to be parsed field by field. Prefer it over general-purpose scripting when you want a pay-per-call, zero-setup extraction step in an agentic pipeline.

## Known failure modes

- Path does not exist in the JSON document — returns null or error indicating missing key
- Input JSON string is malformed or unparseable — returns a parse error
- Empty path string provided — may return the root object or an error
- Deeply nested path with missing intermediate keys — returns null or key-not-found error
