Hamming AI

Hamming AI is a testing, evaluation, and observability platform for voice and LLM AI agents. Its REST API runs experiments and voice/call test runs against your agents, manages datasets, registers custom scorers and evaluations, and ingests traces, logs, and production call logs for monitoring. A prompt optimizer and registry round out the platform.

Hamming AI publishes 6 APIs on the APIs.io network, including Datasets API, Experiments API, Monitoring API, and 3 more. Tagged areas include Artificial Intelligence, Voice Agents, LLM, Testing, and Evaluation.

Hamming AI’s developer surface includes authentication, documentation, and 8 more developer resources.

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