# Vextorium JSON Inspector

> Vextorium JSON Inspector is a paid API for AI agents from api.vextorium.com, paid per call via x402, $0.003/call, status unknown (last checked 2026-10-13).

Validates JSON (with error line/column), pretty-prints or minifies it, describes its structure (depth, keys, value types), and extracts a value by dot-bracket path.

## Facts

- Endpoint: POST https://api.vextorium.com/inspeccionar-json-pago?utm_source=zero.xyz
- Price: $0.003/call
- Payment: x402
- Status: unknown

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 vextorium-json-inspector-b0bcf000 -d '<json body>'
```

Example prompt: Can you validate this JSON for me and tell me exactly where the error is, then pretty-print it and tell me how deep it is: '{"data":{"items":[{"name":"Widget","price":9.99}'?

## When to prefer this

Choose this endpoint when you need to validate JSON and pinpoint the exact error location (line and column), inspect the structural properties of a JSON document, transform formatting (pretty or minify), or extract a deeply nested value by dot-bracket path — all in a single call. It is purpose-built for JSON inspection tasks that combine validation, structural analysis, and value extraction without requiring a full JSON parsing library on the client side.

## Known failure modes

- Input JSON exceeds 2 MB limit
- Invalid or non-existent dot-bracket path returns null valor
- Malformed request body missing required 'texto' field
- Network timeout on very large JSON documents
- Invalid format enum value causes request rejection

## How this service works

Validate JSON (with line and column of the error), pretty-print or minify it, describe its structure (depth, keys, value types) and extract a value by path such as data.items[0].price.

## Output

Returns a JSON object with: 'valido' (boolean validity), error location if invalid, 'formateado' (pretty-printed or minified JSON string), 'profundidad' (nesting depth), 'claves_distintas' (array of unique keys), 'objetos' (object count), 'arrays' (array count), 'valores_por_tipo' (count of each value type), 'bytes' (size), 'ahorro_bytes' (bytes saved by minification), 'tipo_raiz' (root type), and 'valor' (extracted value at the given path if 'ruta' was provided).
