Data Validate

Validate URLs and JSON schemas against format rules.

Validate data formats: URL parsing, JSON Schema (draft-07) validation, email syntax (RFC 5322), and phone format (E.164).

Important: User Consent Required

Before validating any user-provided data, always confirm with the user that they consent to sending the data to an external validation service. Do not autonomously validate data that may contain personally identifiable information (PII) without explicit user approval.

Endpoints

URL Validation

bash

curl -X POST https://validate.agentutil.net/v1/url \
  -H "Content-Type: application/json" \
  -d '{"url": "https://example.com/path"}'

JSON Schema Validation

bash

curl -X POST https://validate.agentutil.net/v1/json-schema \
  -H "Content-Type: application/json" \
  -d '{"data": {"name": "test"}, "schema": {"type": "object", "required": ["name"]}}'

Email Syntax Check

Validates RFC 5322 structure only — no SMTP connection, no inbox verification.

bash

curl -X POST https://validate.agentutil.net/v1/email \
  -H "Content-Type: application/json" \
  -d '{"email": "[e-mail]"}'

Phone Format Check

Validates E.164 format structure only.

bash

curl -X POST https://validate.agentutil.net/v1/phone \
  -H "Content-Type: application/json" \
  -d '{"phone": "[phone]"}'

Response Format

json

{
  "valid": true,
  "url": "https://example.com/path",
  "protocol": "https:",
  "hostname": "example.com",
  "errors": [],
  "request_id": "abc-123",
  "service": "https://validate.agentutil.net"
}

Privacy

All validation is syntax/format checking only. No data is stored or logged beyond the immediate response. No SMTP probing, no payment network contact, no third-party forwarding. Rate limiting uses IP hashing only.
