Tools
| Tool | Description | Behaviour |
|---|---|---|
| compare_listings | Two tools side by side, as markdown: taglines, pricing, API availability, tags — the researched compare facts, honest about unknowns. | Read-only |
| create_order | Turns a quote (from get_quote) into an order, payable for 24 hours. Same account as the quote: its session Cookie header, or its agent key as Authorization: Bearer (order scope). Returns the order with payment.url: POST it without a credential for a 402 card challenge (MPP, method stripe, a Stripe Shared Payment Token), then again with Authorization: Payment. Pass idempotency_key to make a retry return the same order. The price includes any VAT. Nothing is charged by this tool. | Changes data |
| get_best_of | The Published tools in one category, in the order its category page prints (ranked by what we can confirm: a public price, an API and docs, independent sources, stated limits), as a markdown answer sheet. Payment never moves a row. | Read-only |
| get_listing | One tool in full, as answer-first markdown: the summary, then every question on the sheet with its answer, the vendor's own words for it and the URL that proves it. Identical to /{slug}.md and to the HTML page. | Read-only |
| get_quote | A signed price for one offer (from list_offers) on one listing, valid for a short time, and whether the listing can have it now. Only the account that owns the listing gets one: send its session Cookie header, or its agent key as Authorization: Bearer, on the MCP request. Refusals say why and what to do (httpStatus 401 sign_in_required, 403 not_owner with the claim page, 409 not_accepted, already_live, already_bought, category_full). Nothing is reserved or charged. | Read-only |
| list_categories | AgentsIndex's categories with their live listing counts, 0 for one with none yet. | Read-only |
| list_offers | What a listing owner can buy on AgentsIndex, with prices in US cents (VAT included), each offer's term and what it needs. Keyless. Same answer as GET https://agentsindex.ai/api/agent/catalogue. Listing on AgentsIndex is free and never sold: submit_listing. | Read-only |
| my_listings | What the AgentsIndex owner dashboard shows about the listings an account owns: each one's status (`status.kind`: review with the expected date, accepted with `liveOn` and `paid` ('express' | 'featured' | null: the paid way that releases it, Featured including Express review), live, refused with the reason, or archived), the listing as it shows, 30 days of real numbers with the 30 before, where AI answers named the product or cited its page, and what it can buy here at this site's prices. Only for the account itself: send its session Cookie header, or its agent key with "Read your listings" as Authorization: Bearer. Same answer as GET https://agentsindex.ai/api/owner/listings. Read-only: corrections go through the dashboard's request form. | Read-only |
| search_listings | Full-text search over AgentsIndex's Published tools. Returns compact records (name, slug, tagline, url). Fetch depth with get_listing. | Read-only |
| send_lead | Send a buyer-intent enquiry (lead) to a tool or a whole category on AgentsIndex. Keyless. Requires consent:true, a real name, a permanent (non-disposable) email, a message of at least 20 chars, and a target (listingSlug OR categorySlug). Returns { ok, delivered }. Idempotent by (email, target) within 7 days. Nothing here changes a listing's rank, tier or copy. | Changes data |
| submit_listing | Submit a tool to AgentsIndex: the url alone; we write its name and description from its own pages. Requires an existing signed-in account with verified email; send its session Cookie header on the MCP request, or an agent key the account made at https://agentsindex.ai/dashboard/agents as Authorization: Bearer. Identity and email come only from that session or key. Sign in or explicitly create an account at https://agentsindex.ai/login?next=%2Fsubmit and verify its email before retrying. This tool creates no account and sends no verification email. Returns {httpStatus:201, id, slug, status:'Draft'}; research + the quality gate decide publication. Your own (url, session email) replay within 24h returns httpStatus:200. The fit check starts at once and usually answers within a minute: poll GET https://agentsindex.ai/api/submissions/{id} and wait the Retry-After seconds it sends while fit is "checking". fit then reads "accepted" (it goes live, and the account is mailed), "rejected" (mailed with the reason) or "undecided" (a person looks within 2 days). No session: {httpStatus:401, error:'sign_in_required', message, loginUrl}. Unverified session: {httpStatus:403, error:'email_unverified', message, email, remediation}. Company gate: the account's address, or an address it proved with a code, must be on the submitted website's domain; otherwise {httpStatus:403, error:'domain_unverified', message, domain, remediation} — POST /api/domain-proof/start {url, email} mails a 6-digit code to an address at that domain, POST /api/domain-proof/verify {proofId, code} redeems it, then submit again. Personal mailboxes (gmail, outlook…) never prove a domain. No refusal creates a listing. Validation returns 400; duplicate/claim responses return 409. Read tools remain keyless. | Changes data |
| subscribe_newsletter | Double opt-in subscribe to the AgentsIndex digest of new and freshly re-verified tools. Provide an email; returns { ok }. Nothing is sent but one confirmation mail until the person at that address uses its link, which works for 7 days; an unconfirmed address is deleted after 30. Every issue carries a one-click unsubscribe. | Changes data |
