Description
Validate URLs and JSON schemas against format rules.
README (SKILL.md)

data-validate

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

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

JSON Schema Validation

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.

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

Phone Format Check

Validates E.164 format structure only.

curl -X POST https://validate.agentutil.net/v1/phone \
  -H "Content-Type: application/json" \
  -d '{"phone": "+1-555-0100"}'

Response Format

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

Pricing

  • Free tier: 10 queries/day, no authentication required
  • Paid tier: $0.001/query via x402 protocol (USDC on Base)

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.

Usage Guidance
This skill sends user data to an external API (validate.agentutil.net). Before installing or invoking it: (1) verify the service owner and HTTPS certificate for the domain; (2) confirm the privacy claims — you may want to test with non-sensitive data to ensure no logging or retention; (3) note the SKILL.md requires you to obtain explicit consent before sending PII — enforce that in your agent flow; (4) the pricing section mentions an on-chain payment protocol (x402 / USDC on Base) while also saying 'no authentication required' — ask the provider how paid-tier tracking and billing work; (5) if you cannot verify the provider or its privacy/billing model, prefer a local validator (libraries like ajv for JSON Schema) to avoid sending sensitive data externally.
Capability Analysis
Type: OpenClaw Skill Name: data-validate Version: 1.0.2 The skill 'data-validate' is designed to validate data formats (URLs, JSON, email, phone) by sending them to an external API at `https://validate.agentutil.net`. While it involves sending user data to an external service, the `SKILL.md` explicitly instructs the AI agent to 'always confirm with the user' for consent before sending any personally identifiable information (PII). There is no evidence of malicious intent, data exfiltration beyond the stated purpose, obfuscation, or attempts at prompt injection to bypass user consent or perform unauthorized actions. The described actions are consistent with a legitimate utility service.
Capability Assessment
Purpose & Capability
The name/description (URL and JSON schema validation) matches the SKILL.md: it provides curl examples for URL, JSON Schema, email, and phone validation against an external API. There are no unrelated credentials or binaries requested.
Instruction Scope
The instructions explicitly direct the agent to POST user data to https://validate.agentutil.net endpoints. The SKILL.md does require explicit user consent before sending data (especially PII), which is appropriate. This is still a privacy-sensitive operation because validation is performed off-host; the agent will transmit whatever data is provided to the external service if consent is given.
Install Mechanism
Instruction-only skill with no install step and no code files — lowest install risk. The skill uses curl examples but does not install or download code.
Credentials
No environment variables, credentials, or config paths are requested. The skill does not ask for unrelated secrets or elevated access, so requested environment access is proportionate to its purpose.
Persistence & Privilege
always is false and the skill is user-invocable. It does not request persistent or elevated privileges or modify other skills.
How to Use
  1. Make sure OpenClaw is installed (local or Docker)
  2. Run the install command in chat: /install data-validate
  3. After installation, invoke the skill by name or use /data-validate
  4. Provide required inputs per the skill's parameter spec and get structured output
