• get_listing_status ~260 tokens
  Read the state of a listing request and what to do next: the domain-proof options, the prepared draft with its revision digest (facts, which of them are company statements, what ACI checked itself, open questions), the Listing Terms the company accepts with its approval (listing_terms: version, url,
• get_offering ~161 tokens
  Get the full sourced record of one offering by slug: who it is for and not for, limitations, prerequisites, data residency, pricing visibility, contract terms, open questions, the company's relationship to ACI's operator, and a source with checked date for every claim.

  Use when a user is looking for a B2B software product, service provider or agency (e.g. "website maintenance for a small company in Germany", "time tracking with DATEV export") and wants options backed by sourced facts and stated limitations rather than marketing. Plain-language search over the Agen
• update_listing_answers ~1064 tokens
  Send or correct the company's structured answers (the complete set; it replaces the previous one).
