# Alion

> Alion is a live layer of people, companies and AI agents: who they are, whether they are real and active right now, what they do and how to work with them, readable by people and by agents and paid per call.

In the layer right now: 11,158 people with open profiles, 4,375,096 companies (130,042 of them hiring now), 247 AI agents and MCP servers, and 1,971,344 live jobs, 219,618 of them added this week. Counts are served live and change daily; see /methodology for how each one is produced.

Alion (alion.io) is not affiliated with Alion Science and Technology, the United States defence contractor, nor with any other organisation of a similar name.

## What you can get and what it costs

Profiles read in full by get_person. Price: free.
- [Write to a person through Alion](https://alion.io/catalog#person.contact): A structured first message delivered to the person's Alion messages when it passes their filters (role, pay floor, place); otherwise it comes back with the reason. They decide whether to answer; email addresses and phone numbers are never handed out. Price: free.
- [A company's card](https://alion.io/catalog#company.profile.free): Name, verified domain, logo, description, industry, size, founded year, headquarters, social profiles and whether it is hiring now. Price: free. At /company/<slug>.json.

Only slices that hold data are charged. Price: 0.02 credits ($0.002) per company, plus each slice with data, +0.05 credits per slice. Call: get_company (MCP) or /mcp/rest/get_company.
- [Is this company real and active right now](https://alion.io/catalog#company.verify): A verdict on one company: the domain answers, how long it has been seen, whether it hires, opens offices and changes, and what the verdict rests on. Price: pilot.
- [An AI agent's or MCP server's card](https://alion.io/catalog#agent.profile): What it does, for which tasks, where it runs, what it can touch on your machine, how to install it, its repository and its activity. Price: free. At /agent/<slug>.json.

- [One posting](https://alion.io/catalog#job.profile): A posting as its page shows it, with the liveness score, the trust level and the employer's truth index. Price: free. At /job/<slug>.json.

The same list with samples and calls, as JSON: https://alion.io/catalog.json (human page: https://alion.io/catalog). 1 credit = $0.10, paid from the account behind an API key or a signed-in MCP connector - or, with no account at all, per call in USDC over x402 (https://x402.org): call /mcp/rest/<tool> without a key, sign an offer from the PAYMENT-REQUIRED header of the 402 and repeat the call with PAYMENT-SIGNATURE; over MCP, connect https://alion.io/mcp/x402 with no account and pay a tool in params._meta["x402/payment"] (the x402 MCP transport); or with MPP (https://paymentauth.org): answer a WWW-Authenticate: Payment challenge of the 402 (evm = USDC on Base, solana) with Authorization: Payment <credential>.
