## 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 vaaya-signalbase-job-change-feed-348a2580 -d '<json body>'
```

Example prompt: Pull the latest job change signals from Signalbase for new CRO or VP of Sales hires at SaaS companies in the US over the past 30 days — limit to 50 results and source from LinkedIn only.

## When to prefer this

Choose this endpoint when you need real-time, structured executive and role-transition signals filtered by company, geography, seniority, or department — especially for sales prospecting during the classic 90-day new-executive buying window. Prefer it over generic web search or LinkedIn scraping when you need clean, filterable, GDPR-compliant signals from both LinkedIn and press releases in a single API call.

## Known failure modes

- No results returned when filters are too narrow or date range has no matching signals
- Limit exceeded (max 100) returns validation error
- Invalid date format for dateFrom/dateTo causes request rejection
- Unknown enum value for source or seniority causes filter to be ignored or error
- Rate limit or payment failure returns 402 or 429 status

## How this service works

Signalbase — Real-time JOB CHANGE signals: executive moves and role transitions sourced from LinkedIn + press releases (names GDPR-masked). Filters: `date_preset`/`dateFrom`/`dateTo`, `positions`/`departments`/`seniorities` (comma-separated), `new_role`, `keyword`, `company_name`/`company_domain`/`company_linkedin_url`, `personLinkedinUrl`, `countries`/`city`, `source` (linkedin/press_release). `limit` ≤100 — flat price per call. New-exec-in-seat is the classic 90-day buying window.

## Output

A list of job change signal records (up to 100 per call), each containing GDPR-masked person identifiers, their old and new roles, department, seniority level, associated company name and domain, location, signal source (linkedin or press_release), and the date of the transition.
