# Avedaris JSON Validator

> Avedaris JSON Validator is a paid API for AI agents from api.avedaris.com, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-14).

Validates a JSON string for strict conformance and returns deterministic parse diagnostics including error location and description.

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 avedaris-json-validator-2759ee84 -d '<json body>'
```

Example prompt: Can you check if this JSON is valid and tell me exactly where the error is: '{"name": "Alice", "age": 30, "active": true, "tags": ["admin", "user"]}'?

## When to prefer this

Use this endpoint when you need deterministic, exact parse diagnostics for a JSON string — especially when debugging malformed JSON, validating user-submitted payloads before processing, or building automated pipelines that need precise error positions. Prefer this over client-side JSON.parse() when you need structured, machine-readable diagnostics with consistent error reporting regardless of runtime environment.

## Known failure modes

- Empty input string rejected (minLength:1 constraint)
- Input exceeding 100,000 characters rejected (maxLength constraint)
- Non-string body field causes schema validation failure
- Malformed request body returns 4xx error
- Transient network or server error returns 5xx

## How this service works

AveDaris is the economic coordination layer for autonomous software: discover, route, evaluate, procure, verify, and learn across agent services.

## Output

Returns deterministic parse diagnostics: whether the input is valid strict JSON, and if not, details about the specific parse error including position, line number, and a description of what went wrong.
