Search the JLCPCB component catalog by keyword and/or parametric filters, enriched with live pricing. The catalog (descriptions, packages, attributes, categories) comes from a local SQLite snapshot. Each result reports jlc_assembly_stock (catalog — the figure that matters for PCBA) and lcsc_retail_stock (live LCSC retail, a different pool; a 0 here is NOT an assembly shortage). Ranked Basic-first, then by assembly stock, then unit price. Examples: '10k resistor 0805', 'STM32F4', 'ceramic capacitor'.

Get full details for a specific JLCPCB part: catalog metadata (manufacturer, package, category), pricing tiers, parametric specifications, datasheet, and images, plus stock from both pools — jlc_assembly_stock (catalog snapshot, authoritative for PCBA) and lcsc_retail_stock (live LCSC retail). An LCSC-retail 0 is NOT an assembly shortage.

Get stock for a specific JLCPCB part from BOTH inventory pools: jlc_assembly_stock (JLCPCB assembly availability, from the catalog snapshot — the number that matters for PCBA) and lcsc_retail_stock (LCSC retail, live from wmsc.lcsc.com). These are DIFFERENT pools: an LCSC-retail 0 does NOT mean a part is unavailable for assembly (common for Basic parts). Treat assembly stock as authoritative for board production.

Get live quantity-break pricing tiers (USD unit price per quantity ladder) for a specific JLCPCB part.

Get the datasheet PDF URL for a specific JLCPCB part. Prefers the live API value and falls back to the catalog snapshot.

List the component categories and subcategories available in the local catalog, each with a component count. Optionally filter to a single top-level category. Useful for discovering valid category filter values for searches.

Report the status of the local component catalog database: whether it exists, its file path, size, component count, and when it was last built/refreshed.

Download and rebuild the local component catalog from the latest yaqwsx/jlcparts snapshot. Downloads ~50MB and may take several minutes. Use occasionally to pick up newly added components (live stock/pricing is always current regardless).

Official JLCPCB Parts API (authenticated): authoritative details — specs, stock, pricing, and attributes — for one or more LCSC part codes. More complete than the public live endpoint. Requires API credentials.

Official JLCPCB Parts API (authenticated): browse the full assembly component library, paginated. Requires API credentials.

Official JLCPCB Parts API (authenticated): list YOUR account's private / consigned component library (parts you hold at JLCPCB), paginated. Only available with API credentials.

Official JLCPCB Parts API (authenticated): cursor-paginated bulk feed of the component catalog. Pass the lastKey returned by a previous call to page through the entire library. Requires API credentials.

Official PCB API: upload a Gerber archive (zip) for quoting/ordering. Returns a fileKey to pass to jlcpcb_pcb_calculate_price / jlcpcb_pcb_create_order. Requires API credentials.

Official PCB API: upload a blind/buried-via stackup image for boards that need one. Requires API credentials.
