How this service works
Invoice-to-JSON, on-chain tools (transaction explainer + payment check, wallet profile, contract ABI, ERC-20 token risk), company contacts and web-to-RAG for AI agents. Pay per call with x402 (USDC on Base). No signup, no API key.
Output
Returns a JSON object with an array of company records, each containing the domain, company name, description, detected technologies (e.g. React, Cloudflare), social media links, key pages, and email provider. Also includes a top-level count of successfully enriched companies.
Example use cases
Lead list tech stack enrichment
“I have a list of prospect domains — hubspot.com, salesforce.com, and pipedrive.com — can you enrich them all and tell me what technologies, email providers, and social profiles each one has?”
Competitor technology audit
“Can you check what tech stack our top 5 competitors are running? The domains are figma.com, canva.com, sketch.com, adobe.com, and invisionapp.com — I want to see their detected technologies and descriptions.”
Startup research for investor due diligence
“I'm looking at a few early-stage startups — can you pull company profiles for linear.app, vercel.com, and planetscale.com including their social accounts, key pages, and any tech stack signals you can find?”
Technical details
Endpoint
GEThttps://freetier-agent-api.pages.dev/api/company-batch?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to enrich multiple company domains (up to 10) in a single API call and want both profile data (name, description, socials, email provider) and technology detection. It is ideal for B2B lead enrichment, competitor research, and sales intelligence workflows where you need structured company metadata without accessing personal data. Prefer this over single-domain lookups when processing batches, and over full web scrapers when you only need lightweight company profiles and tech signals.
Side effects
- More than 10 domains submitted — API rejects or truncates the list
- Invalid or non-existent domain returns empty or null company record
- Domain resolves but has no detectable tech stack, returning empty technologies array
- Rate limiting or payment failure (x402 payment required) blocks the request
- Malformed comma-separated domains string causes query parse error
