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 is listed with 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.
Regulatory Posture applies to this provider. Its tags matched the
AI & Biometrics 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 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.
The six quality facets above are damped to 85 points between them,
because the conditional facet above carries the other
15. That is why each facet's contribution is shown against a damped
maximum: raising a quality facet moves the composite by 85% of its nominal
weight, not 100%. The full arithmetic is at apis.io/rating/.

Agent readiness — checks not met, largest first (exact, from this profile):
Idempotency+9 pts — OpenAPI mutating operations declare an idempotency key — a header, a request-body property, or a named de-duplication token whose own description says so (verified); else common[].type matches /idempoten/i (documented)
Request/Response Examples+7 pts — share of operations carrying request/response examples; else an Examples / Code Samples link
Delegated User Identity+6 pts — a served discovery document listing authorization_code in grant_types_supported (served), else an oauth2 authorizationCode flow or openIdConnect declared in an OpenAPI (documented)
7 more unmet checks in the Agent Readiness table above.
Kin Score — facets with the most composite points still available (weight × headroom):
The Kin Score Market layer reads a provider inside its market:
its position, and how deep its integrations go. Depth is only comparable within a position. Provisional and unweighted:
not part of the Kin Score or agent readiness.
Registered MCP server and declares compatibility are report only — not weighted.
Undeclared means we found nothing we can read, so there is no number: we never infer integrations.
Standards this provider implements or carries. De facto ones are profiled and measured by the API Commons; formal ones come from the standards directory and are linked by the provider's own tags. The evidence column says how each claim was established — not that it was made.

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.
