Haystack / deepset

Haystack is deepset's open-source Python framework for building context-engineered, production-ready LLM applications - modular Pipelines and agent workflows assembled from 100+ Components and document stores for RAG, semantic search, and agents. Haystack pipelines deploy as REST services via Hayhooks, and the commercial deepset AI Platform (deepset Cloud) exposes a hosted REST API at api.cloud.deepset.ai for pipelines, search, files, and workspaces.

Haystack / deepset publishes 8 APIs on the APIs.io network, including Files API, Pipelines API, Search API, and 5 more. Tagged areas include Artificial Intelligence, LLM, RAG, Open-Source, and Orchestration.

Haystack / deepset’s developer surface includes authentication, documentation, engineering blog, and 9 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/haystack-ai: open an issue to ask a question, or submit a pull request to add artifacts.
