Touchmark

Touchmark is solving AI pricing - instead of AI being priced per token regardless of quality, Touchmark prices it by the quality, efficiency, and value of the output, so spend is fair, predictable, and tied to what you actually get. Applications emit the events they already produce (model outputs, tool calls, code diffs) with a base price, and Touchmark's out-of-band judge returns a quality-adjusted fair price for each event on a separate valuation stream. A Y Combinator Summer 2026 company founded by Ilia Bolgov and Roman Yanushevskyi in San Francisco; the TypeScript SDK (@touchmark/sdk) is in private beta.

Touchmark publishes 1 API on the APIs.io network. Tagged areas include Company, Artificial Intelligence, AI Pricing, Billing, and Monetization.

Touchmark’s developer surface includes documentation, API reference, getting-started guide, authentication, and 18 more developer resources.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/touchmark: open an issue to ask a question, or submit a pull request to add artifacts.

  note: 'Renamed from MCPServer 2026-09-03 (roadmap#247): the manifest self-describes as status: candidate — a tool list derived
    from the published API contracts, not an existing server. The scorer already read the manifest and reported mcp_server
    correctly; the MCPServer type was crediting the artifact-type surfaces with a server that does not exist.'
