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 list of person records each containing profile details (name, title, company, LinkedIn URL, contact info) and a similarity_score between 0 and 1 indicating closeness to the reference. Also includes metadata with echoed filters, pagination parameters, and credit usage (credit, topup_credit, total_credit_cost).
Example use cases
Lookalike prospecting from best customer
“I have a great customer — their LinkedIn is https://www.linkedin.com/in/john-smith-vp-sales. Can you find me 25 people similar to him on Pubrio, ideally at SaaS companies with 11 to 200 employees?”
Talent sourcing from reference candidate
“We love this candidate's profile — https://www.linkedin.com/in/alice-zhang-data-engineer. Use Pubrio to find me similar people, limited to companies in the cloud infrastructure space.”
Building lookalike list from job title
“I want to find people similar to a 'Head of Growth at a Series B startup' — can you pull a list of lookalike contacts from Pubrio filtered to companies in the US with 50 to 500 employees?”
Technical details
Endpoint
POSThttps://agents.pubrio.com/people/search/similar?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to discover new contacts who resemble a known reference person — ideal for lookalike prospecting, talent sourcing, or expanding a persona-based list. Prefer this over general people search when you have a seed identity (LinkedIn URL, Pubrio ID, or job title) and want similarity-ranked results rather than filter-only results. Choose this over company-level endpoints when the unit of interest is an individual professional rather than an organization.
Side effects
- HTTP 416 if page exceeds subscription max_search_page or per_page exceeds max_search_per_page (code 41613)

- Invalid UUID format in peoples array returns validation error
- No results returned if filters are too restrictive in combination with the reference
- Credit exhaustion results in a credit-related error response
