• update_inbound_assistantA

  ErzyCallA

  Update an inbound voice assistant after reading it and explicitly confirming the exact change. Pass the opaque revision from get_inbound_assistant with either systemPrompt text or systemPromptId selection. Text creates an assistant-local prompt without mutating a shared library prompt. For transient assistants it applies to new calls. For permanent assistants it is allowed only when WhatsApp routes on active integrations are listed, applies only to new WhatsApp LiveKit calls, and leaves the provider-hosted phone prompt unchanged; archived integrations do not qualify, while a disabled call config remains visible with enabled=false. Permanent assistants without qualifying WhatsApp routes return UNSUPPORTED_CONFIG_MODE. systemPrompt and systemPromptId are mutually exclusive. Use update_whatsapp_agent for TEXT CHAT prompts.

• start_visibility_checkA

  Asked ThriceA

  Measure whether a brand shows up when buyers ask AI assistants for a recommendation. Asks real buyer questions to OpenAI, Anthropic and Gemini and reports what they answered, not what they claim they would answer. Free, no signup, one measurement per domain every 30 days. Returns a runId: call get_visibility_check with it after about a minute. If the domain was already measured this month the response says quota_reached and includes when it ran.

  Beste KI ToolsA

  Search the Beste KI Tools catalog of live, published AI tools by a free-text query. Matches on tool name, tagline, or category name (case-insensitive substring). Call this first when a user asks to find, discover, or compare AI tools by keyword, use-case, or category (e.g. 'agents', 'writing assistants'). Returns up to 20 results.

• request_auditA

  The Profound AgencyA

  Request a free audit of whether AI systems — ChatGPT, Perplexity, Google's AI Overviews and crawling agents — can reach, read and quote a website. Scored out of 100 across crawler access, structured data, answer readiness, agent files, off-site authority and freshness, from public data only: no logins, no analytics access and nothing installed. Free, and nothing is purchased or committed. Use this when a client wants to know why assistants do not mention them; use submit_campaign_brief when they already want to buy media. A person reviews every audit and replies to the contact email — this tool does not return a score.

• github-repo-preflightA

  SALT19 Agent Utility GridB

  GitHub repository due diligence for coding agents: evaluate whether a public or open-source repository is safe and maintained enough to adopt using license, maintenance, release freshness, activity, project health, and risk signals. Price: $0.10 via x402. Generate one _salt19_operation_id per intended purchase, preserve it across retries, and add _x402_payment_signature after satisfying the challenge. A stable _salt19_operation_id is required and makes semantic retries at-most-once. _salt19_operation_id is recommended but optional for standard x402 compatibility.

  New Runtime public recordsA

  Use when the free tools left a question open and you can pay per call: lists New Runtime's x402 tools (find the primary source of a claim $0.10, rumour check $0.40, research bundle, prior-coverage check) with endpoint, USDC price, input example, when you are charged, and how to pay without an account. Free to call.

• ai_checkA

  VegvisAI guideA

  Checks how a public website looks to AI assistants: robots.txt, sitemap, schema.org, llms.txt, ai-catalog.json, and text that looks like prompt injection. Returns a score out of 100, the points per check and concrete actions. Uses the yardstick that fits the site: business, government (public bodies), organisation (NGOs, associations), party (political parties) or media (news media); it is detected unless given. Blocking only AI training bots can be a deliberate choice and costs 5 of 20 points; blocking the bots that fetch pages for users costs the other 15. Also lists what the site has open for AI: feeds, actions, APIs, MCP and open data. Takes 5–15 seconds.

• share_sessionA

  spacesheepA

  Share one of your coding sessions (source and session_id from list_sessions) read-only, with the same access choices as a space, at its own link: spacesheep.dev/session/<id>. Whoever it opens to sees where the session stands, the pages and PRs it made (only the pages they could open anyway) and the whole conversation; never the machine, folders, harness account, resume commands, claude.ai link or Talk. With only source and session_id it returns the link, making it if needed; a new link opens for no one until people are added or access is widened. Returns the link, who can open it and the people on its list. get_session reports whether a session is shared.

• search_businessesA

  MRR LedgerA

  Use when the user asks how much revenue, MRR or ARR an AI agent, AI startup or AI tool makes, or wants real examples of AI businesses in a niche (support, coding, voice, sales, automation...). Returns AI-agent businesses with sourced, dated revenue (start here). Example: {"query":"coding","limit":3} -> 3 coding agents with their sourced revenue. Use it to find or filter businesses (keyword, category, tier, verified_only) when you have no slug; for a pure top-N use leaderboard, for one full record get_business. Each brief: slug, name, category, tier, one_liner, annualized_revenue_usd, basis, confidence, verification_label ("reported, not payment-verified" unless processor-verified), url_profile; + total + next page (offset/cursor, limit max 50). Empty query = all, highest revenue first. Cost: free (100 calls/day without a key).

• leaderboardA

  MRR LedgerA

  Use when the user asks which AI agents or AI startups make the most money, or for a top-N revenue ranking. Returns businesses ranked by latest sourced annualized revenue, highest first (same briefs, with verification_label, as search_businesses). Example: {"category":"coding-agents","limit":5} -> the top 5 coding agents by revenue. Use it for a pure ranking or top-N, optionally per category or verified_only (limit max 50); it has no keyword search, use search_businesses for that. Cost: free (100 calls/day without a key).

• health_state_medical_board_nyA

  SiteCheck Health & TravelB

  New York medical board disciplinary actions (NYS DOH Board for Professional Medical Conduct open data since 1990): search physicians and physician or specialist assistants by license number or name for every public action: date, license type, action (revocation, suspension, probation...) and case summary. An empty result means no public action; it is not a licence-status check. Price: $0.002 in USDC per successful call, paid with x402 (Base, Solana or Arc); failed calls are not charged.

• contract_abiA

  Agent Data Tools: Chain dataA

  The verified ABI of a smart contract on Ethereum, Base, Arbitrum, Optimism or Polygon from Sourcify's open verification repository: contract name, compiler, match quality, every function and event signature, the full ABI, and for proxies the implementation contract with its ABI. Optional source=true adds the main source file (up to 20,000 characters). Unverified contracts are an uncharged 404. Use before calling or decoding a contract. Example: address=0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48. Price $0.01/call via x402 USDC or a card key (/credits), first 25 free; failed calls free. Reads or computes only and changes nothing; each call is charged, so repeats are not free.

  Agentic.ai DirectoryA

  Get AI-powered tool recommendations for a specific need. This is the recommended starting point — describe what you're looking for in natural language and get curated, ranked results with explanations.

Examples: - "best coding agent for a small startup on a budget" - "open source alternative to Cursor for VS Code" - "autonomous customer support agent with MCP support" - "self-hosted data analysis tool for enterprise"
