Pixeltable is an open-source (Apache 2.0) Python data infrastructure company building a unified multimodal backend for AI data applications. A single `pip install pixeltable` provides declarative storage, transformation, indexing, retrieval, serving and versioning of images, video, audio, documents and structured data through computed columns that run AI inference incrementally on insert, embedding indexes that stay in sync for vector search, Python UDFs and query functions, and built-in table history and revert. The same declarative schema runs locally via `pxt serve` or a FastAPI router and deploys to Pixeltable Cloud via `pxt deploy` for managed databases, R2-backed media buckets, Deploy endpoints and serverless scale-to-zero workers. Pixeltable integrates 25-plus AI providers including OpenAI, Anthropic, Gemini, Hugging Face, Bedrock, Groq, Mistral, Together, Fireworks, Ollama and Whisper, and positions itself as a replacement for the glue between object storage, Postgres, a vector database, an orchestrator and a framework such as LangChain. The company is unusually agent-forward: it publishes an A2A agent card, a callable read-only WebMCP server, an NLWeb ask endpoint, an installable Agent Skill, markdown representations of its pages, and scoped llms.txt context files. A public REST API with OpenAPI and scoped OAuth is stated as in active development.
Pixeltable publishes 3 APIs on the APIs.io network. Tagged areas include Company, Ai Data, Multimodal AI, AI Data Infrastructure, and Vector Search.
Pixeltable’s developer surface includes documentation, API reference, getting-started guide, support, engineering blog, pricing, signup flow, and 31 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/pixeltable: open an issue to ask a question, or submit a pull request to add artifacts.

description: The authenticated HTTP API behind the Pixeltable Cloud dashboard and the `pxt` CLI. The provider publishes
the base URL https://internal-api.pixeltable.com in /.well-known/agent.json and marks it authenticated_only, noting that
a public OpenAPI is in development. Cloud API keys are sent as X-api-key; the control plane additionally requires a WorkOS
AuthKit session. Anonymous probes of the host returned HTTP 500 on every path and /api/v1 on the apex host returned 401
no_session_cookie_provided, so no machine-readable contract could be read.

detail: STEP 0b ran in full and found no REST contract. https://pixeltable.com/openapi.json returns HTTP 200 but its body
is an honest placeholder — {"status":"planned","message":"Public Pixeltable Cloud REST API OpenAPI spec is in active development."}.
/openapi.yaml, /swagger.json, /v1/openapi.json, /api-docs, /docs and /redoc were probed on the apex, docs and internal-api
hosts with no hit. GraphQL introspection found no endpoint. What the provider DOES publish is a live MCP server (anonymous
tools/list returns real inputSchemas) and a conformant A2A agent card, so the machine-readable contract here is MCP, not
OpenAPI. No tool crosswalk was emitted because there is no OpenAPI to bind tools to.
