discover_offeringsread-only

Browse every published offering in the Agent Company Index (B2B software and services, sourced facts, explicit limitations), in stable alphabetical order. Prefer search_offerings when the user describes a need; use this to page through the whole index.

get_offeringread-only

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 before recommending or comparing a provider.

search_offeringsread-only

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 Agent Company Index; returns matching offerings with the terms they matched. Order: offerings matching m

evaluate_situationread-only

Check a structured buyer situation (category, company size, country, requirements) against every published offering and get each offering's fit or exclusion with reasons, limitations and unknowns. Each result states its group: fit (fit_state strong_contextual_fit), possible fit (possible_fit), insufficient information (insufficient_information) or excluded (eligibility excluded, with the reason).

request_listing

List one offering of the company you act for in the Agent Company Index. Listing is free. Before calling, fill answers from the company's website and ask the user for the rest: what problem the offering solves (primary_problem), who it fits best (positive_fit) and who not (negative_fit), two to four use_cases, the countries it serves (market_country), support_languages and pricing_model. Leave out

update_listing_answerscan modify

Send or correct the company's structured answers (the complete set; it replaces the previous one). Once a draft exists this requests changes: ACI prepares a new revision from the answers within a few minutes, and any earlier approval no longer counts. Put every fact you want changed into answers; a free-text note is kept with the request, is not published and does not change the draft by itself.

verify_listing_domain

Prove control of the company domain for a listing request: pass email_code with the code the user received at the company address, or call without it after the DNS TXT record or the /.well-known/aci-verification.txt file is in place.

get_listing_statusread-only

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, sha256, summary), or the public URL once published. Show the user the draft and the Listing Terms s

approve_listingcan modify

Approve publication of the exact draft revision on behalf of the company and accept the Listing Terms (LT-2, https://agentcompanyindex.com/legal/listing-terms/lt-2) for it. Requires a verified domain. Before calling: show the user the draft, then the listing_terms summary and link from get_listing_status, and ask whether they may act for the company, approve this exact revision and accept the List

request_listing_removalcan modify

Remove a company from the Agent Company Index on behalf of that company. Give the company's domain and a work email address on exactly that domain (ask the user for it). ACI emails a private confirmation link to that address; once someone there opens it and presses Remove, every published profile of the domain goes offline within a few minutes and the company gets an email. Nothing changes without
