## 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-pubrio-free-seller-api-quote-purchase-guide-972cedea -d '<json body>'
```

Example prompt: Before I spend anything, can you get me a free quote for searching Pubrio for companies expanding into Japan — I want to know the exact API contract, cost per call, and what I need to get started?

## When to prefer this

Use this endpoint before any paid Pubrio API call to discover the correct endpoint, confirm pricing, understand prerequisites, and plan budget — especially useful for autonomous agents that need wallet-free pre-flight checks or for developers onboarding to the Pubrio ecosystem without yet having credentials or payment methods configured.

## Known failure modes

- status: 'needs_input' when the goal description is too vague to match an API contract
- status: 'unsupported' when the described task does not match any available Pubrio endpoint
- status: 'unavailable' when the quoting service is temporarily unreachable
- status: 'blocked' when the request violates policy or includes disallowed content
- Empty or unhelpful guide text when minimal goal detail is provided

## 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 JSON object containing a status enum (quoted, ready, needs_input, blocked, unknown, unsupported, or unavailable), a priceUsd of '0' confirming no charge, a markdown guide with the matched API contract, exact pricing, prerequisites, and next steps, plus a guideUrl for wallet-free follow-up planning.
