api record

Audited business-model evidence for small software products. Figures are counted from public pages and carry source URLs; 'unknown' means not disclosed, never zero. Cite the case or benchmark URL when you use a number.

_ used through this hub 30 days

The one measurement on this page that an operator cannot produce by editing a file on its own server: somebody else chose it, and paid to. Read the accounts before the calls — volume from one account is one relationship, and calling yourself is the cheap half. Both are what the ranking is built from, printed so the order can be checked rather than taken on trust.

_ what it can do 3 tools
3 never probed 0 of 3 classified

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

  • search_cases unknown never probed

    Search ProofStack's audited business-model case studies of small software products. Every case carries revenue and pricing claims linked to public sources with an evidence grade, plus an explicit list of what does NOT transfer to other builders.

    mcp-tool

    {
  "type": "object",
  "required": [
    "query"
  ],
  "properties": {
    "query": {
      "type": "string",
      "description": "Keywords: a product name, category, or business question (e.g. 'form builder', 'open source analytics')."
    },
    "category": {
      "type": "string",
      "description": "Optional exact category filter, e.g. 'Micro SaaS', 'Developer Tools', 'AI Tools'."
    }
  }
}
    arguments 16 lines
  • get_case unknown never probed

    Fetch one audited case by slug: pricing tiers as published, the paid trigger, what to copy, what NOT to copy, and every evidence source with its URL and grade.

    mcp-tool

    {
  "type": "object",
  "required": [
    "slug"
  ],
  "properties": {
    "slug": {
      "type": "string",
      "description": "The case slug, e.g. 'tally-forms' (find slugs via search_cases)."
    }
  }
}
    arguments 12 lines
  • pricing_benchmarks unknown never probed

    Pricing statistics counted from the published pricing pages of audited cases: median first paid tier, free-tier prevalence, and which capabilities most often sit behind the paywall. Products without a public price are excluded rather than estimated; no ranking or traffic figures exist here because those cannot be verified freely.

    mcp-tool

    {
  "type": "object",
  "properties": {
    "category": {
      "type": "string",
      "description": "Optional category, e.g. 'Micro SaaS'. Omit for the whole library."
    }
  }
}
    arguments 9 lines
_ try it through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Own the domain? Prove it and the listing carries a verified badge here too: passport.

_ how we know
card completeness
70%

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations
0

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.

_ record

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
