## 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-bytemine-ai-bytemine-free-api-quote-and-purchase-guide-e1589796 -d '<json body>'
```

Example prompt: I want to enrich about 300 contacts by email using Bytemine — can you get me a free quote showing the exact API contract, price per call, and the steps I need to follow to get started, paying via x402?

## When to prefer this

Use this endpoint before making any paid Bytemine API call, especially when you are unsure which endpoint matches your task, what the per-call price is, or what prerequisites exist. It is the canonical pre-flight step for autonomous agents that need to plan spend without a wallet or prior authorization. Prefer this over guessing at endpoint paths or calling paid endpoints blindly.

## Known failure modes

- Status 'needs_input' returned when the goal description is too vague to match a specific API contract
- Status 'unsupported' when the described task has no matching Bytemine endpoint
- Status 'unavailable' when the Bytemine backend is temporarily unreachable
- Status 'blocked' if the request violates policy constraints
- Empty or minimal guide when required fields like 'goal' are missing (validation error)

## How this service works

Bytemine is a B2B data platform for sales and go to market teams. It covers contact and company search across 135M professionals and 10M companies, contact and company enrichment, LinkedIn profile search and enrichment, live company intelligence read from a company's own web presence, technographics, buying intent scoring, and hiring, funding, job posting, and job change signals. Search results bill per record returned, enrichment bills only on a successful match, and count queries are free. This server is a pay-per-use, transparent proxy in front of Bytemine'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 JSON object with a status field (e.g. 'quoted', 'ready', 'needs_input'), a priceUsd always equal to '0' for this lookup call, a markdown-formatted guide containing the matched API contract, itemized pricing, prerequisites, and next steps, and a guideUrl pointing to a wallet-free advisor endpoint for follow-up planning or recovery.
