Technical details
Endpoint
POSThttps://mpp.orthogonal.com/openmart/api/v1/search?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to discover or list multiple local businesses matching a natural language description with rich filtering (ownership, price, reviews, revenue, location). Prefer this over the Only Ids endpoint when you need full business details, and over the Enrich Company endpoint when you don't already have a specific company URL to look up.
Side effects
- No results found for overly narrow query or filter combination
- Invalid filter category values cause a 400 error
- Query too vague returns irrelevant or unrelated businesses
- Location not recognized or unsupported region outside US/CA/AU
- Payment failure (insufficient USDC balance) prevents call execution
- Rate limit exceeded returns 429 error
