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
Returns a JSON object with the original query, search type used, provider name, number of results, and an array of result objects each containing URL, title, relevance score (0–1), author, published date, optional text body, and optional highlights array. A findings array is also included for any structured extractions.
Example use cases
Recent news on a competitor
“Search the web for recent news articles about OpenAI published after March 1 2025 — give me up to 10 results with highlights so I can skim the key points.”
Research paper discovery
“Find me research papers about transformer attention mechanisms — use neural search, category research paper, up to 8 results.”
Domain-scoped GitHub search
“Search GitHub for repositories related to 'micropayments HTTP protocol' — restrict to github.com, neural mode, top 5 results.”
Technical details
Endpoint
GEThttps://netintel-production-440c.up.railway.app/web/searchWhen to prefer
Choose this endpoint when you need ranked web search results with relevance scores, date filtering, category filtering, or domain restriction — especially when you want neural semantic search (via Exa) rather than keyword matching. Prefer it over generic scraping endpoints when you need discovery across many pages rather than content extraction from a known URL. Its pay-per-call x402 model with no API key makes it suitable for agent workflows that need on-demand search without pre-registration.
Side effects
- Missing required 'query' parameter returns a validation error with no charge
- num_results above 10 is clamped to 10 silently
- snippets mode clamping num_results to 2 may surprise callers expecting more results
- Invalid date format for start_published_date or end_published_date causes input-validation rejection with no charge
- include_domains with more than 20 hostnames may be truncated or rejected
- Upstream search provider outage returns server error with no charge billed
- Very short or ambiguous queries may return low-relevance results with low scores
