How this service works
Plain-HTTP twin of the Alion MCP server. Every tool is also a GET/POST endpoint. Send "Authorization: Bearer <key>" (a key from https://alion.io/developers/keys); calls are paid from the account's credits. Or pay a paid tool per call in USDC with x402 (https://x402.org), no account: call it without a key, sign one of the offers in the PAYMENT-REQUIRED header of its 402 and repeat the call with the PAYMENT-SIGNATURE header; or with MPP (https://paymentauth.org): answer a WWW-Authenticate: Payment challenge with Authorization: Payment <credential> (USDC on Base or Solana, a transfer you sign or have sent). Docs: https://alion.io/developers
Output
Returns a JSON object with an array of lookalike companies each scored by similarity, including name, domain, industry, size band, headquarters, hiring data (open jobs, new jobs in 30 days, last job posted), shared industry segments, shared technologies, ATS vendor, and employer type. Also includes metadata about the target company, pagination info (has_more, next_cursor, returned count), and any warnings or filters applied.
Example use cases
Competitive landscape mapping for a fintech
“Show me the top 15 companies most similar to Plaid — I want to see their industry segments, shared technologies, and how many jobs they're hiring for right now.”
Sales prospecting for lookalike accounts
“I'm targeting companies like Shopify for my outbound sales. Can you find 20 lookalike companies, ideally headquartered in the US, with standard detail so I can see their size and tech stack?”
Investor peer group benchmarking
“We're benchmarking Databricks for a deal — can you pull a list of companies that look most similar to them, up to 25, with full detail including founded year and hiring signals?”
Technical details
Endpoint
GEThttps://alion.io/mcp/rest/company_lookalikes?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to discover companies that closely resemble a known target company — ideal for competitive intelligence, sales prospecting, investor benchmarking, or market mapping. Prefer this over general company search when you have a specific anchor company and need ranked similarity with technology and segment overlap signals. Best when the target company has a well-known domain (e.g. stripe.com) that Alion can resolve exactly.

- Missing or invalid API key returns 401 Unauthorized
