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
A paginated array of signal objects, each containing the event date and precision, polarity (expansion or contraction variant), source type (jobs, ads, linkedin, news, pubrio), country code, optional evidence URL, signal-type-specific metadata (e.g. job departments or ad headlines), audit provenance fields, and active/retracted status.
Example use cases
Auditing a competitor's market entry evidence
“Show me the raw expansion signals behind Shopee's entry into new markets between March 2025 and June 2025 — I want to see the source type and any evidence URLs, just live signals, expansion polarity only, first page of 25.”
Detecting early contraction signs
“Pull the most recent contraction_leading and contraction_confirming signals for ByteDance across any market in 2025, page 1 with 25 results, so I can see what's being retracted.”
Tracking executive-hire signals for market expansion research
“Search for EXEC and HIRE expansion signals dated between January 1 2025 and June 30 2025, active only, give me page 1 with 25 results per page — I'm researching which companies are staffing up for new market pushes.”
Technical details
Endpoint
POSThttps://agents.pubrio.com/expansions/signals/search?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need the raw, row-level evidence behind a company's expansion stage — individual dated signal rows with source provenance and evidence links — rather than aggregated summaries or ranked lists. Use it for auditing, building custom analytics pipelines, or verifying specific market-entry events. Prefer the Expansion Search endpoint for discovering which companies are expanding, and the Expansion Overview for market-level KPIs.
Side effects
- HTTP 416 returned when requested page exceeds subscription's max_search_page limit
- HTTP 416 with code 41676 when per_page exceeds subscription's max_search_per_page
- Invalid signal_type enum values cause validation errors
- Empty result set when no signals match the specified filters and date range
- Null evidence_url on most rows since many signals are derived from structured sources without a citable page
