## 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 agents-pubrio-com-company-signal-events-ce7ba237 -d '<json body>'
```

Example prompt: Pull up all the expansion signal events for stripe.com over the last 90 days — I want to see what markets they've been moving into, with the AI summary included, 25 results per page starting at page 1.

## When to prefer this

Use this endpoint when you need a granular, event-by-event view of a specific company's expansion activity rather than a high-level summary. It is ideal for sales timing, account research, or competitive intelligence where you need the raw signal events with evidence, dates, and types — and need to paginate through a large event history. Prefer this over the general company search when you already know the target company and want expansion-specific detail.

## Known failure modes

- HTTP 416 if requested page exceeds subscription's max_search_page limit
- HTTP 416 with code 41676 if per_page exceeds subscription's max_search_per_page
- No events returned if company has no expansion signals in the requested window
- Invalid domain or LinkedIn URL format causes lookup failure
- Missing all three identifier fields (domain_search_id, domain, linkedin_url) returns validation error

## How this service works

Pubrio detects when companies enter new markets and returns the company and people data behind each move. Expansion signals (local hiring, new offices and entities, localized ads, news, cloud hosting) are typed, dated and tied to evidence across 200+ markets, with strong coverage of Asia-Pacific and other markets that Western-built datasets miss. The graph covers 800M+ companies and 560M+ contacts from 50+ local data sources, refreshed daily. Search companies, people, job postings, news, ads and cloud footprints with filters or a plain-language query; look up records by domain, LinkedIn URL or Pubrio id; find lookalike companies and people; read hiring, news, advertising and cloud insights for one company; and reveal verified work emails, personal emails and phone numbers. Each call costs the number of credits listed on its endpoint. This server is a pay-per-use, transparent proxy in front of Pubrio's own API: it handles identity, payment, and proxying. Agents can purchase autonomously or with their human's approval. The complete verified paid surface is listed at /openapi.json, the source of truth for available operations. Each operation here carries its live price in x-payment-info. Use the operations and details here when they meet your needs. Filtered specs contain only matching operations; if you cannot find what you need here, use search or the service catalog. The live catalog at /manifest.json is authoritative for prices and any free included units (prices[].includedUnits) - some meters include free usage per account before any charge, reserved for agents claimed by a human with a verified email.

## Output

Returns a paginated array of typed, dated expansion signal events for the requested company (newest first), each tied to evidence sources. Includes an optional AI-generated summary rolling up the page's events, plus pagination metadata (page, per_page, total_entries, total_pages).
