  title: Hamming AI REST Datasets API
  description: REST API for the Hamming AI testing, evaluation, and observability platform for voice and LLM AI agents. Covers experiments and test runs, voice/call testing, datasets, custom scorers, monitoring/tracing ingestion, and the prompt registry. Endpoints and request shapes are derived from Hamming's public documentation (docs.hamming.ai) and the official open-source SDKs (github.com/HammingHQ/evals-py, evals-ts). Authentication uses a Bearer API key created at hamming.ai/settings.
