## 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-endpoint-272b157f
```

Example prompt: Can you pull buying-intent signals for stripe.com and give me the geo score and outbound sequence bundle so I can prioritize them for this week's SDR campaign?

## When to prefer this

Choose this endpoint when you need a real-time, single-call buying-intent score for a specific B2B domain along with a ready-made outbound sequence bundle, and you are operating within an x402 micropayment-enabled agent workflow where per-call USDC billing is acceptable.

## Known failure modes

- Missing or invalid 'url' query parameter returns an error or malformed response
- Non-HTTPS URLs may be rejected by the input schema validation
- Payment not completed via x402 protocol results in 402 Payment Required before data is returned
- The download_bundle_url may point to an external CDN that is independently unavailable
- Domain with no detectable buying-intent signals may return a low or zero geo_score

## 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 a boolean ok status, the queried domain, a numeric geo_score (0-100 range indicating buying-intent strength by geography), a PRO license key string, and a download_bundle_url pointing to a ZIP archive of the outbound sequence assets.
