## 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-outbound-sequence-engine-4b0b49e5
```

Example prompt: Pull the buying-intent signals and outbound sequence bundle for stripe.com using NexusSDR AI so I can see their geo score and download the personalized outreach package.

## When to prefer this

Choose this endpoint when you need real-time B2B buying-intent scoring combined with a ready-to-deploy outbound sequence bundle for a specific company domain, especially when a geo-weighted intent score and downloadable asset package are required in a single call.

## Known failure modes

- Missing or invalid 'url' query parameter returns an error
- Target domain is unreachable or not a valid HTTPS URL
- Payment of $6500 USDC not fulfilled via x402 protocol results in 402 response
- Bundle generation fails and download_bundle_url is unavailable
- Rate limiting or serverless cold-start timeout

## 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 an 'ok' boolean, the analyzed domain name, a geo_score (0-100 intent/geo signal), a PRO license key string, and a download_bundle_url pointing to a ZIP archive of outbound sequence assets.
