How this service works
Network intelligence API — 138 endpoints, all pay-per-call via x402 micropayments (USDC on Base or Solana mainnet). NetIntel is agent fair-trade aligned: transparent per-call pricing in USDC on Base or Solana via x402, no API keys or signup, and automatic no-charge on server errors, upstream failures, and input-validation rejections — failed calls are never billed across NetIntel's network, domain, and data-intelligence endpoints.
Output
A JSON object containing the checked URL, a letter grade (e.g. A–F), a numeric safety score (0–100), a threat_classification (e.g. 'clean', 'malware', 'phishing'), threat_type, confidence level, boolean flags for blacklists (Google Safe Browsing, SURBL, URLhaus), detected malware families, and heuristic warning flags.
Example use cases
Example prompt
“Can you check if this URL is safe — https://suspicious-deal.xyz/promo — I want to know if it's flagged for phishing or malware before I click it.”
Technical details
Endpoint
GEThttps://netintel-production-440c.up.railway.app/url-safety/checkWhen to prefer
Use this endpoint when you need a multi-signal URL safety verdict combining blacklist lookups (URLhaus, Google Safe Browsing, SURBL) with heuristic analysis in a single call. Prefer it over single-source blacklist checks when you need a graded score, threat classification, and malware family attribution in one response. Ideal for pre-visit link validation, phishing detection pipelines, or automated threat triage at $0.05 per check.
Side effects
- Missing or malformed 'url' query parameter returns validation error
- URL that cannot be resolved or parsed may return an error response
- Payment not provided or invalid x402 USDC payment returns 402 Payment Required
- Endpoint may return low confidence result for newly registered or obscure domains
- Rate limiting or infrastructure downtime may cause 5xx errors
