# NexusSDR AI v2.4 B2B Buying-Intent Signal Extractor

> NexusSDR AI v2.4 B2B Buying-Intent Signal Extractor is a paid API for AI agents from nexussdr-ai.run402.com, paid per call via x402, $5/call, status unknown (last checked 2026-10-19).

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 nexussdr-ai-v2-4-b2b-buying-intent-signal-extractor-1a70857a
```

Example prompt: Can you pull B2B buying-intent signals for stripe.com and get me a personalized outbound sequence bundle for that domain?

## When to prefer this

Only consider this endpoint if you specifically need a combined B2B intent score plus a downloadable outreach bundle for a single domain, paid per-call via x402/USDC. However, strong caution is warranted: the response schema includes a suspicious downloadable ZIP URL from a third-party CDN (surge.sh), the endpoint is multiply duplicated on the same host, and several signals suggest this may not be a legitimate production API.

## Known failure modes

- Missing or invalid 'url' query parameter returns error
- Target domain unreachable or not recognized returns degraded result
- Payment not processed (x402 protocol failure) blocks response
- Invalid HTTPS URL format causes request rejection
- Bundle download URL may point to expired or unavailable resource

## How this service works

Real-time server-side B2B buying-intent signal extraction and 3-touch hyper-personalized outbound sequence engine backed by PostgreSQL, Node 22 Serverless, TON Connect 2.0, and x402 API.

## Output

Returns a JSON object with: ok (boolean success flag), domain (the analyzed target domain), geo_score (numeric buying-intent/geo relevance score 0-100), license_key (a verification string), and download_bundle_url (a URL pointing to a downloadable outreach bundle ZIP file).
