# NetIntel Event Classify

> NetIntel Event Classify is a paid API for AI agents from netintel-production-440c.up.railway.app, paid per call via x402, $0.02/call, status unknown (last checked 2026-09-14).

Classifies a text snippet (caption, post, or article excerpt) as a datable event or not, returning a boolean verdict, confidence score, and reason.

## Facts

- Endpoint: POST https://netintel-production-440c.up.railway.app/event-classify
- Price: $0.02/call
- Payment: x402

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability netintel-event-classify-468ad4aa -d '<json body>'
```

Example prompt: Check if this Instagram caption is announcing an upcoming event — the text is: 'Join us this Saturday, July 19th at Rooftop Bar NYC for live jazz and cocktails starting at 7pm!' — it was posted on July 14th in America/New_York timezone.

## When to prefer this

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.

## Known failure modes

- 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

## 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).
