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 a 'data' field containing: is_event (boolean indicating whether the text describes a classifiable upcoming event), confidence (0–1 float), and reason (a short explanatory string). Also includes meta (model used, e.g. haiku-4.5), grade (letter A–F), score (0–100 numeric), and findings (array of supporting details).
Example use cases
Event post filter for social feeds
“I have this Twitter post and I need to know if it's describing an actual scheduled event or just general content: 'Don't miss our Summer Sale — Friday July 25th only, 10am–6pm at our downtown store!' — posted today, timezone is America/Chicago.”
Automated event calendar ingestion
“Before adding this to our events calendar, can you verify whether this text actually describes a dateable upcoming event? The snippet is: 'We're hosting a free webinar on AI safety on August 5th at 3pm EST — sign up now!' — posted_at is 2025-07-01T09:00:00Z.”
Spam vs real event moderation
“I'm moderating user submissions and need to know if this post is a genuine event announcement or not: 'Our annual charity run is back — September 13th, Golden Gate Park, registration opens Monday.' The user is in America/Los_Angeles timezone.”
Technical details
Endpoint
POSThttps://netintel-production-440c.up.railway.app/event-classifyWhen to prefer
Choose this endpoint when you need a fast, cheap ($0.02/call), pay-per-use classifier to determine whether a piece of text describes an upcoming, dateable event — especially useful for filtering social media streams, moderating user submissions, or pre-screening content before adding it to an event calendar. Prefer it over general-purpose LLM prompting when you want a structured JSON verdict (boolean + confidence + reason) with deterministic billing and no API key setup. The posted_at context parameter makes it especially useful when you need to reject past-event recaps automatically.
Side effects
- Text exceeds 10,000 words or 50KB — input validation rejection, no charge
- Missing required 'text' field — 400 validation error, no charge
- Upstream model failure — server error, no charge
- Invalid ISO-8601 posted_at format — validation rejection, no charge
- Invalid IANA timezone string — validation rejection, no charge
- Low confidence classification when text is ambiguous — returns is_event with confidence near 0.5
