  • request_listingchangeddescription, input schema
    before

    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. Domain control: when work_email is on the company's own domain, ACI mails it an 8-digit code that the user gives back to you (verify_listing_domain email_code); otherwise 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.

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).

    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 summary with its link before asking for approval.

  • update_listing_answerschangeddescription
    before

    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.

    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.

  • evaluate_situationchangeddescription
    before

    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.

    Approve publication of the exact draft revision on behalf of the company. Requires a verified domain. Only call after the user has seen the draft and said it is correct; the approved revision then goes live automatically within a few minutes. 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.

    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.

approve_listingdestructiveApprove 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.

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.
discover_offeringsread-onlyBrowse 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.
evaluate_situationread-onlyCheck 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.

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.
get_listing_statusread-onlyRead 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.
get_offeringread-onlyGet 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.
request_listingList 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.
request_listing_removaldestructiveRemove 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.
search_offeringsread-onlyUse 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.
update_listing_answersdestructiveSend 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.
verify_listing_domainProve 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.
