Lakekeeper Generic Table (Data) API

Lakekeeper's data-plane API served under /lakekeeper/v1, cataloging non-Iceberg table formats — Lance, Delta, CSV, Parquet — alongside Iceberg tables in the same Warehouse and Namespace, with the same credential vending and access control. Six operations across four paths covering list, create, load and drop of generic tables, plus a referenced-by lookup. Consumed by the official pylakekeeper Python client and the Lakekeeper Java/Spark clients.

This API exposes 6 operations across 4 paths, and defines 11 schemas. It is described by OpenAPI 3.2.0, at version 0.0.0.

Requests are made against a single base URL, {scheme}://{host}{basePath}.

Where this information came from

This is an independent, third-party profile of Lakekeeper Generic Table (Data) API, published by API Evangelist. We do not operate, host, resell, or support these APIs, and we are not affiliated with or endorsed by the company unless stated above. Everything here is built from publicly available information — the company's own site, developer portal, documentation, public repositories, and the specifications it publishes for public use. Nothing is obtained by breaching a system, defeating an access control, or using credentials.

The Kin Score and Agent Readiness rating are independently calculated assessments of a company's public API artifacts, scored against a published rubric. They are not certifications, endorsements, security assessments, or audits.

Corrections, re-scores, and removal are free — no partnership or purchase required, and you do not need to justify the request. A removed company is recorded as unrated, never scored zero for having asked. Acknowledgement within one business day; removal within two.
