Feed Audit (Product Feed Hygiene)

Full product feed hygiene scan of a product feed URL (Google Shopping-style XML, CSV, or JSON — format auto-detected). Fetches the feed server-side and runs 20 weighted checks: parse validity and encoding, required attributes (id, title, link, price, availability values, image_link), GTIN/MPN and brand coverage, identifier_exists misuse, title/description quality, image-link spot-checks, price format and sale_price logic, taxonomy and shipping/tax presence, duplicate ids and variant grouping. These are the errors behind Google Merchant Center disapprovals — a disapproved feed means the products do not serve on Google Shopping at all, and agent-commerce surfaces referencing Merchant Center IDs inherit the same dirt. Returns machine-readable JSON: 0-100 score, A-F grade, a disapproval-risk level (Low/Moderate/Elevated/High) with the failing disapproval-class checks named, per-check pass/partial/fail/unknown with evidence, the worst-offending items sampled with concrete fixes, and the top 3 prioritized fixes. HONEST LIMITS: the scan validates the feed document (capped at 8 MB, first 20,000 items, 8 image spot-checks); it does not crawl landing pages, so feed-vs-page price/availability mismatches are out of scope. Cost: $1.00 USDC on Base per call, paid via x402 — the caller's agent pays from its owner's approved wallet; no API key needed. Use this after every catalog change, before a Shopping campaign launch, or to triage a disapproval wave.

FREE lite product feed hygiene scan of a product feed URL (XML, CSV, or JSON — auto-detected). Runs the same 20 checks as audit_feed but returns top-line results only: 0-100 score, A-F grade, disapproval-risk level, detected format, item count, check counts, and the titles of the top gaps — item-level detail is capped (no per-check evidence, no offending items, no detailed fixes). Use this to triage whether a feed needs the full audit_feed report, or call audit_feed directly for the complete evidence-backed scan.
