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 Listing Terms on the company's behalf. Call only after an explicit yes from that person; never on your own. Pass the approver's full name, role and the company's legal name. When the domain was confirmed with a DNS record or a file, also pass approver_email (an address on the company domain the approver reads): ACI mails it a confirmation link and publication waits for it. The approved revision is then published automatically, usually within minutes; the approver gets an email record of the approval and the terms. When the domain was confirmed with the emailed code, ACI sends a free monthly report (which AI assistants and systems retrieved the profile) to that address; set monthly_report to false if the user does not want it. Every report has an unsubscribe link.
Full name of the person approving for the company.
The company's legal name (e.g. from its imprint), the party accepting the Listing Terms.
Set to "LT-2" only after the user explicitly accepted the Listing Terms (https://agentcompanyindex.com/legal/listing-terms/lt-2) on behalf of the company.
Required when the domain was confirmed with a DNS record or a file: an address on the company domain the approver reads. Ignored when the domain was confirmed with the emailed code (that address is recorded).
Send the monthly report to the confirmed work address (default true).
Optional: the user's reply agreeing to approve and to the Listing Terms, quoted word for word.

}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). The list is ordered by more documented fit reasons first, then fewer cautions, then fewer unknowns, then offering id; it is not sorted by group, so group the results by those fields when presenting them. Payment, client status and ownership by ACI's operator are not inputs to the order. ACI publishes no scores and no paid positions. Use when the situation maps to the schema categories; for plain-language needs use search_offerings. free_text is accepted but not interpreted: only the structured fields decide fit.

}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 (also while an update of it is being prepared). Show the user the draft and the Listing Terms summary with its link before asking for approval.

}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 anything you cannot confirm; unanswered fields stay visible on the profile as open questions. Returns a reference and a private listing token: tell the user to keep both, the token is shown only once. work_email must be an address on the company's own domain that the user reads ([email protected]); a free-mail or other-domain address is refused at once, because the approval is recorded for a mailbox on the domain (a company without one writes to ACI). Domain control: ACI mails that address an 8-digit code that the user gives back to you (verify_listing_domain email_code); where no code can be sent, a DNS TXT record or a file. Show the user the returned option word for word. ACI then drafts the profile from the website in a few minutes (get_listing_status). Once a person who may act for the company approves one exact revision and accepts the Listing Terms (approve_listing), it is published automatically. Payment never changes fit or order.
| Argument | Type | Description |
|---|---|---|
| notes | string | |
| answers | object | Optional structured company answers for the draft. Each becomes a company statement on the profile, shown with its date. Unanswered fields stay open questions. |
| website* | string | The company's own domain, e.g. example.com. |
| work_email* | string | An address on the company's own domain (e.g. [email protected]) that the user can read: ACI mails it a code that confirms the domain without DNS changes. A free-mail address (Gmail, GMX, web.de, Outlook …) or an address on another domain is refused. |
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 that confirmation. Profiles under an agreement with ACI's owner are checked by a person first.
| Argument | Type | Description |
|---|---|---|
| domain* | string | The company's own domain, e.g. example.com |
| work_email* | string | An address on exactly that domain; the confirmation link goes there. |

}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 more of the query's words come first, then by name; offerings matching fewer than half as many words as the best match are left out. Payment, client status and ownership by ACI's operator are not inputs to the order. ACI publishes no scores and no paid positions. Follow up with get_offering for the full record.

}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. After publication the same call updates the published profile: ACI reads the website again and prepares a new revision (unchanged answers are fine); the public profile stays as it is until the company approves that revision and it passes the automated check. 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.
