Check the extraction status of one or more parts. Free. Each entry includes the current extraction step, elapsed seconds, and document ID.

Use after prefetch_datasheets or after read_datasheet triggers a new extraction.

Recommended polling cadence: every 10-15 seconds. A datasheet nobody has read before usually takes 1-3 minutes (a large one 5 or more), so faster polling wastes calls. Keep polling while the status is 'resolving', 'queued', 'pending' or 'extracting'; stop once it is 'ready', 'failed', 'no_source' or 'unsupported'.

DATASHEET STATUS VALUES:

• 'ready' — extracted and indexed; call read_datasheet, search_datasheets, or analyze_image.

• 'extracting' / 'in_progress' / 'queued' / 'pending' — extraction running or scheduled. Poll check_extraction_status every 10-15s until 'ready' or 'failed'. A datasheet nobody has read before usually takes 1-3 minutes; a large one can take 5 or more.

• 'resolving' — we're still looking for the datasheet's PDF (distributors, then a web search; under a minute a part, longer for a big batch). Not final: keep polling check_extraction_status.

• 'not_extracted' — known part but datasheet hasn't been fetched yet. Trigger it via prefetch_datasheets (up to 20 parts) or by calling read_datasheet (auto-triggers on first read).

• 'no_source' — the search for a public datasheet has finished and found none for this MPN. Check the part number (search_parts), or retry prefetch_datasheets later. Otherwise upload the PDF via request_datasheet_upload + confirm_datasheet_upload (see those tools). Org-uploaded datasheets are private to the org.

• 'unsupported' — PDF exists but can't be extracted (scanned image-only, encrypted, or corrupted). Upload a clean text-based PDF via request_datasheet_upload to override.

• 'failed' / 'error' — extraction errored. The response includes the error reason. Retry via prefetch_datasheets or escalate to support.

• 'rejected' — input wasn't a real MPN (bare value like '100nF', description, or reference designator). Fix the input and re-call.

• 'deduplicated' — another part in the family already has this datasheet; same content is returned under the primary MPN.
