## 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-find-lookalike-companies-785143a2 -d '<json body>'
```

Example prompt: Find me companies that look like salesforce.com, hubspot.com, and marketo.com — filter results to SaaS companies in the US, and send results to my webhook at https://myapp.com/webhooks/lookalikes.

## When to prefer this

Use this endpoint when you have a set of known good-fit companies and want to discover net-new prospects that share similar business characteristics. Ideal for ABM list expansion, competitive landscape mapping, or feeding a sales pipeline with lookalike accounts. Prefer this over a general company search when you want similarity-driven discovery rather than keyword or attribute filtering. The async job model makes it suitable for bulk prospecting workflows where results don't need to be synchronous.

## Known failure modes

- More than 10 domains supplied — request rejected with validation error
- None of the seed domains can be enriched — job may return empty results or fail
- Invalid filter values (unknown industry or country code) — may return no results or error
- Job ID not found when polling — if polled before processing completes, status will be pending
- Webhook URL unreachable — results lost if webhook delivery fails and polling is not used
- Rate limit or payment failure — 402 returned if payment cannot be processed

## 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. This document is the source of truth for agents: it lists the complete verified paid surface with each operation's live price in its x-payment-info. Endpoints not listed here are not part of the supported 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 job_id immediately for async polling. When complete, the job yields an array of up to N similar companies, each with name, website, industry, company_id, employee_count, and a similarity_score. Also returns the extracted business keywords used to drive the search. Results can be delivered via webhook if a webhook_url was provided.
