# Delete a crawl seed

> Cascades over documents with `web_source_id = seed_id` AND
`origin: web_source` (vectors + chunks + rows). Documents
with `origin: user` that the seed had adopted survive and lose
their `web_source_id`. Requires `editor`+.

  title: Knowledges API
  description: >
    Public REST API for the Prisme.ai Knowledges (storage) workspace: knowledge
    bases, documents (uploaded files, web pages, remote files, connector
    documents), recurring web-crawl sources, semantic search, access control,
    per-knowledge-base API keys, and skills.


    Resource identifiers use the physical prefixes emitted by the implementation
    (`vs_` knowledge base, `vsf_` document, `seed_` web source, `kb-` API-key
    slug).


    This spec documents the public REST surface only. Internal helpers (private
    automations prefixed with `_`) and admin/GDPR lifecycle operations are not
    part of the public contract.
