  "instructions": "Deterministic acceptance report for a supplied product catalog: validates price/currency/availability/URL formatting, GS1 GTIN checksums, and flags duplicate SKUs, duplicate GTINs, and grouped-variant collisions. Checks only the structured rows given in the request - no network calls, no brand or marketplace certification, no ISO 4217 currency list. Tool calls cost 0.05 USDC on Base. Initialization, tool discovery and unpaid price challenges are free. Send x402 v2 PAYMENT-SIGNATURE on the POST or params._meta['x402/payment']. Reuse the identical input and authorization when recovering a pending purchase; do not sign a fresh charge. Results are retained24hours. Validates only the structured rows supplied in the request - never fetches url, and never checks live marketplace or vendor status. currency is checked for exact three-uppercase-letter format only, not against the ISO 4217 currency code list. gtin is checked for digit format, length (8/12/13/14), and GS1 checksum only - this confirms the number is well-formed, not that it is assigned to a real product or that brand is a legitimate registered trademark. Duplicate SKU rows are always reported, even when two rows are byte-for-byte identical; nothing is silently deduplicated. A group_id used by only a single row is never an error by itself - collisions are only flagged when two or more rows share both the same group_id and an identical canonical attribute map. Bounded input: request body must serialize to at most 131072 bytes, at most 500 products, JSON nesting depth at most 12, and at most 20000 total JSON nodes. No network access, no persistence, and no external certification of any kind is performed. Results at most 96 KiB; retry identical input and authorization within 24 hours to recover a purchase.",
