# Leadralia

> Leadralia is the smart business directory, where businesses speak in their own words. It is updated regularly.

## Start here

- [Leadralia business data](https://leadralia.com/data.md): what our business data holds and how to get it, as plain text. The same page for people: https://leadralia.com/data. Open to every person and every bot, with no limit.

## Who may read this site by machine

People are always welcome. Every bot may read the data page, the developer docs (For developers, below), robots.txt and this file, with no limit. The rest of the site is open by machine only to the services below, each within its scope:

- Search engines (Googlebot, Bingbot, DuckDuckBot, YandexBot, SeznamBot, Qwantbot, Applebot): read and index the public pages. Applebot reads at a limited rate.
- Link previews (facebookexternalhit, Twitterbot, LinkedInBot, Slackbot, WhatsApp, TelegramBot, Discordbot, Pinterestbot, SkypeUriPreview, MicrosoftPreview): the page a person shares.
- AI search and assistants that fetch a page for a person (OAI-SearchBot, ChatGPT-User, Claude-SearchBot, Claude-User, DuckAssistBot, MistralAI-User): read, quote and link back to the page.
- The AI training crawlers named in our robots.txt: at a slow pace, at most ten requests an hour each.
- Perplexity (PerplexityBot, Perplexity-User) and Grok (GrokBot, xAI-Grok, Grok-DeepSearch, xAI-SearchBot): at most ten requests an hour for each of the two, all its bots together.

A name alone is not enough: where an operator publishes how to check its crawler, we check it.

## Everything else is refused

Every other automated access is not allowed and is refused (HTTP 403). That covers other crawlers and AI agents, scrapers, SEO tools, HTTP libraries, headless browsers, and any client that uses an allowed name without being that service. Services that resell what they read are refused by name.

## How to ask for access

A bot, or the company behind it, that wants to use our pages or our data writes to support@leadralia.com and tells us:

- who it is: the company, the user agent and the addresses it reads from;
- what it wants to read, and what for;
- how much: requests a day, or pages in all.

We answer by e-mail.

## Business data

- [Business data](https://leadralia.com/data.md): what the business data holds, country by country, what each record holds and what it costs, as Markdown. The same page for people: https://leadralia.com/data

## For developers

- [Robots rules](https://leadralia.com/robots.txt): the same list, as robots read it.
- [API reference](https://leadralia.com/api/v1/docs): the Leadralia API, with its own keys and limits.
- [OpenAPI document](https://leadralia.com/api/v1/openapi.json): the machine-readable description of the API.
- [Prices and quickstart](https://leadralia.com/developers): free calls once for each company, the current prices, and examples in curl, Python and JavaScript.
- [API licence](https://leadralia.com/api-license): the directory's business data is licensed to a company for its own activity. The steps: a free account, the licence application in Settings, API keys, a code mailed to an address on the company's own domain, our approval, then the key.
- [Annual feed](https://leadralia.com/developers#feed): the whole directory and everything that changed in it, by annual contract.
- [Pure-Inbox](https://leadralia.com/developers#verify): check e-mail addresses, one or a list of up to 200,000, with `POST /api/v1/verify` and `POST /api/v1/verify/lists`. Only a definite answer is charged; the first 100 checks are free.
- [Search](https://leadralia.com/api/v1/directory/search?q=plumber+in+Houston): the directory's search as an API. E-mail addresses never appear in search results or lists.
- [MCP connector](https://leadralia.com/mcp/directory): the public directory tools for assistants, no sign-in.
