  • get_businessFree

    Full public detail of one 53ON business by its slug: services, ratings, product catalog with prices, and the link where the user can request a quote and pay. Use the slug returned by search_providers.

  • search_providersFree

    Find local businesses and independent professionals on 53ON by what they do. Accepts free text in Spanish or English and resolves synonyms, so "plumber" and "destapar caneria" both work. Pass lat and lng to limit results to that area; without them the search is nationwide. Call with an empty query to get the list of services 53ON covers.
