`check_fit`read-only	Does this part fit that machine? Returns a verdict with the rule id and version that decided it, or the missing fields. Example: {"subject_id":"e3d-v6-1-75mm-brass-nozzles-0-40mm-1-75mm","target_id":"prusa-mk4s"}
`check_stock`read-only	Availability and price per merchant, re-verified live when the data is over an hour old. Example: {"product_id":"e3d-v6-1-75mm-brass-nozzles-0-40mm-1-75mm","merchant_id":"e3d-online-com"}
`compare`read-only	Side-by-side spec table with offers and the fields that differ. Pass 2-10 product_ids, or a category with filters. Example: {"product_ids":["prusa-core-one","bambu-lab-p1s"]}
`get_product`read-only	Full specs with per-field confidence and source, every offer with verified time, 30/90-day price range, and the top fits per category with counts. Example: {"product_id":"prusa-mk4s"}
`report_issue`	Flag a wrong spec, price or fit verdict. Reports never edit facts; two independent reports mark a fact disputed. Example: {"entity_type":"product","entity_id":"prusa-mk4s","field":"nozzle_thread","claim":"MK4S uses the Nextruder thread"}
`search_products`read-only	Find products by name or by category and spec filters; returns key specs and the best in-stock offer. Example: {"query":"hardened 0.4","category":"nozzle","limit":5}
