Measured tools (15)

• search_businesses read-only

  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, SEO...). Returns AI-agent businesses with sourced, dated revenue (start here). Example: {"query":"support","limit":3} -> 3 customer-support agents with their sourced revenue. Each brief: slug, name, category, tier, one_liner, annualized_revenue_usd, basis, confidence, url_profile; + total + next page. Empty query = all, highest revenue first; filters category, tier, verified_only; limit max 50, offset/cursor. Next: get_business {"slug"}. Cost: free (100 calls/day without a key).

  Parameters:

  • tier — string — Funding-based, not size-based: venture = raised outside venture money (even if small), indie = bootstrapped/founder-funded, experiment = agent-run or research project.
  • limit — number — Results per page. Default 10, max 50.
  • query — string — Keyword, e.g. "support", "coding", "voice". Empty = all businesses.
  • cursor — string — Opaque page token: page.next_cursor from the previous call with the same query and filters.
  • offset — integer — Skip this many matches (page start). Default 0. Use page.next_offset from the previous call.
  • category — string — Category slug, e.g. coding-agents, customer-support (see list_categories).
  • verified_only — boolean — Keep only businesses whose headline figure is payment-processor verified (headline_verification not null).

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• benchmark_business read-only

  Use when the user gives their own MRR or asks whether their revenue is good compared with similar AI businesses. Returns where an MRR ranks among fresh same-category MRR peers (rank of N + 1 comparable). Example: {"category":"customer-support","mrr":2000} -> your rank among the customer-support MRR peers + 1 comparable. Also: N, basis, verification date, peer caveat; no growth numbers yet; your MRR is never stored. Cost: free (100 calls/day without a key).

  Parameters:

  • category (required) — string — Category slug, e.g. customer-support, automation-platforms, sales-gtm, indie-solo (see list_categories).
  • mrr (required) — number — Your monthly recurring revenue in USD, e.g. 2000 (greater than 0, at most 100000000). Not stored.
  • full — boolean — Full answers are paused (paid tier paused while we confirm source permissions); you get the free answer.
  • months_live — integer — Optional months since launch (0-600). Accepted but ignored for now.
  • report_token — string — Not used while the paid tier is paused.
