JSON Tools for AI Agents: Validate, Format, and Analyze via API

AI agents deal with JSON constantly — parsing API responses, validating data, extracting specific values, reformatting for downstream tools. Most agents handle this inline with custom code. IteraTools now has a dedicated endpoint for JSON operations so agents can offload all of this to a single API call.

What /json/validate does

POST /json/validate handles 5 modes in one endpoint:

1. validate — check syntax, get error position if invalid
2. format — pretty-print with configurable indent (2, 4, or tab)
3. minify — compact output with savings percentage
4. stats — depth, total key count, type map, top-level keys
5. get — extract value by dot-bracket path (user.name, items[0].id)

All processing is local — no external API, instant response, $0.001/call.

Examples

Validate JSON

curl -X POST https://api.iteratools.com/json/validate \
  -H "Authorization: Bearer YOUR_KEY" \
  -H "Content-Type: application/json" \
  -d '{"json": "{\"name\": \"John\", \"age\": 30}"}'

Response: {"ok": true, "valid": true, "data": {"formatted": "{\n \"name\": \"John\",\n \"age\": 30\n}", "keys": 2, "depth": 1, "mode": "validate"}}

Get stats on complex JSON

curl -X POST https://api.iteratools.com/json/validate \
  -H "Authorization: Bearer YOUR_KEY" \
  -H "Content-Type: application/json" \
  -d '{"json": "[{\"id\":1,\"name\":\"Alice\"},{\"id\":2,\"name\":\"Bob\"}]", "mode": "stats"}'

Response: {"ok": true, "valid": true, "data": {"keys_total": 4, "depth": 2, "type": "array", "array_length": 2}}

Extract a nested value

curl -X POST https://api.iteratools.com/json/validate \
  -H "Authorization: Bearer YOUR_KEY" \
  -H "Content-Type: application/json" \
  -d '{"json": "{\"user\":{\"name\":\"Alice\",\"role\":\"admin\"}}", "mode": "get", "path": "user.name"}'

Response: {"ok": true, "valid": true, "data": {"path": "user.name", "value": "Alice", "found": true, "type": "string"}}

Minify JSON

curl -X POST https://api.iteratools.com/json/validate \
  -H "Authorization: Bearer YOUR_KEY" \
  -H "Content-Type: application/json" \
  -d '{"json": "{\n  \"name\": \"John\",\n  \"age\": 30\n}", "mode": "minify"}'

Response: {"ok": true, "valid": true, "data": {"minified": "{\"name\":\"John\",\"age\":30}", "savings_pct": 45}}

Also new: AI Document OCR

We also added POST /document/ocr — AI-powered OCR via Mistral:

• Extracts text, Markdown AND structured tables
• Handles scanned PDFs, forms, invoices, receipts
• $0.015/request

Why this matters for agents

Agents that process APIs, webhooks, or databases often need to:

• Validate that data received from users or services is valid JSON before processing
• Extract specific fields without writing path-traversal logic
• Format JSON for display or logging
• Analyze the structure of unknown JSON payloads

With IteraTools, one API call handles all of this. No libraries to import, no custom code to maintain.
