# NEXUS Agent Utilities – Extract JSON

> NEXUS Agent Utilities – Extract JSON is a paid API for AI agents from x402.nexusword.it, paid per call via x402, $0.02/call, status unknown (last checked 2026-10-03).

Extracts structured JSON data from unstructured or semi-structured text input, returning a parsed JSON object

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 nexus-agent-utilities-extract-json-910f9d42 -d '<json body>'
```

Example prompt: Take this block of text and extract it into a clean JSON structure: 'Order ID: 12345, Customer: Jane Doe, Total: $49.99, Status: Shipped'

## When to prefer this

Choose this endpoint when you need a deterministic, cheap ($0.02 USDC), and fast way to convert unstructured or semi-structured text into a JSON object within an autonomous agent workflow. It is especially suited for agents operating in x402-payment-enabled environments that need reliable structured data extraction without integrating a full LLM parsing pipeline. Prefer this over general-purpose LLM calls when cost predictability, determinism, and machine-readable output are the priority.

## Known failure modes

- Malformed or ambiguous input text may result in incomplete or incorrectly structured JSON output
- Text with no discernible structure may return an empty or minimal JSON object
- Exceeding input text length limits may cause a request error
- Payment failure or insufficient USDC balance (x402 payment required at $0.02 per call) will result in a 402 response blocking the request
- Network timeout if the service is temporarily unavailable

## Output

Returns a JSON object containing the extracted structured data parsed from the input text, with fields and values inferred from the content (e.g. {"data":{"id":123}}). The shape of the output adapts to the structure present in the input text.

## Request schema (JSON Schema)
