How this service works
Verified business leads for AI agents: structured business records with public phone, website and other contact intelligence, provenance, verification and freshness when available. $0.02 USDC per requested result.
Output
A JSON object containing the search query echo, result count, a list of matching business entries with public phone numbers and provenance metadata, and payment confirmation. Returns an empty results array if no matches are found for the given city, state, and category combination.
Example use cases
Finding local service providers for travel
“I'm heading to Austin, TX next week — can you find me up to 5 auto repair shops there using the Global Machine Directory so I have options if something goes wrong with my car?”
Agent-driven lead generation for sales
“Pull up to 25 accounting firms in Chicago, IL from the machine-payable business directory — I need their phone numbers with provenance for my sales outreach list.”
Hyperlocal business research for a report
“Search the Global Machine Directory for gyms in Boston, MA — give me up to 15 results with verified phone evidence so I can compare coverage across the city.”
Technical details
Endpoint
POSThttps://property-change-x402-production.up.railway.app/v1/directory/searchWhen to prefer
Choose this endpoint when an AI agent needs structured, machine-payable access to a business directory with phone evidence and provenance — particularly for US city+state+category lookups where verifiable contact data matters. Prefer over generic web search when you need structured JSON output with sourced phone numbers rather than scraped or unverified web results.
Side effects
- Empty results array returned when no businesses match the category/location combination
- Invalid or unsupported US state abbreviation causes query failure or empty response
- Limit value outside 1–25 range rejected by schema validation
- Missing required fields (city, state, or category) may result in malformed query or error
- Payment failure (x402) prevents query from completing if USDC balance is insufficient
