Scorecard

Scorecard is a simulation and evaluation platform for building, testing, and deploying frontier AI agents. Teams run their agents through thousands of realistic scenarios, judge outputs with configurable AI, human, and heuristic metrics, and ship new capabilities with confidence. The platform organizes work into Projects, Testsets, Testcases, Metrics, Runs, Records, Scores, and Systems, and exposes a REST API (bearer API keys prefixed ak_) plus official Python, TypeScript/Node, and Go SDKs, a hosted MCP server, tracing integrations for LangChain, the Vercel AI SDK, and the Claude Agent SDK, and a GitHub Actions integration for evals in CI. Scorecard was founded to solve AI agent evaluation at scale and is backed by Kindred Ventures.

Scorecard publishes 7 APIs on the APIs.io network, including Metrics API, Projects API, Records API, and 4 more. Tagged areas include Company, Artificial Intelligence, Agents, Evaluation, and Testing.

Scorecard’s developer surface includes documentation, API reference, getting-started guide, engineering blog, pricing, signup flow, changelog, and 22 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Horizontal (data, software, accessibility, platform) regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.

The six quality facets above are damped to 75 points between them, because the conditional facet above carries the other 25. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 75% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

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/scorecard: open an issue to ask a question, or submit a pull request to add artifacts.
