Tools: search_cases get_case pricing_benchmarks
search_cases | 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. params: query*, category |
get_case | 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. params: slug* |
pricing_benchmarks | 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. params: category |
Entries describe changes in tool definitions. They are not statements about a server, its quality or its author. The grade measures how the tool definitions fit model providers (token cost, schema compatibility, confusable names) as scored by the ToolFit engine at the time of the listing. JSON: append .json.
