PAL Commerce Catalog Intelligence is an AIEO remediation API for AI shopping and agentic commerce. It audits and corrects the structured signals machines use to understand products — identifiers, links, images, price, availability and variant consistency — while preserving Merchant Center compatibility.
Use these routes to make catalog records more explicit and machine-readable for AI commerce. PAL does not promise ranking or inclusion on any AI channel; it improves the quality and consistency of the product data those systems may consume.
Process 1–2,000 product records in one paid call and receive one prioritized AIEO remediation plan for AI-readable commerce data, with Merchant Center/feed compatibility.
POST /v1/usdc/catalog-remediation-bulkProcess 1–500 product records in one paid call and receive prioritized AIEO fixes for machine readability plus Merchant Center/feed compatibility.
POST /v1/usdc/catalog-remediation-batchTurn 1–100 product records into a prioritized remediation plan with concrete corrective actions and affected product IDs.
POST /v1/usdc/catalog-remediationCheck duplicate IDs, GTIN validity, URLs, price format, availability and brand/MPN consistency for up to 100 records.
POST /v1/usdc/catalog-auditValidate GTIN-8, UPC/GTIN-12, GTIN-13 and GTIN-14 structure and check digits.
POST /v1/usdc/gtin-checkStatically inspect x402 v2 payment declarations for network, asset, amount, recipient and timeout consistency.
POST /v1/usdc/x402-validateA plain validator tells you what is wrong. The remediation endpoints group findings by priority and issue code, explain business impact, and return concrete corrective actions. Use the $1 route for up to 100 products, the $5 batch route for 101–500 products, and the $20 full-catalog route for up to 2,000 products when you want one payment and one result.

The first unpaid request returns HTTP 402 with the exact Base-USDC payment requirement. After settlement, retry the same request with the x402 payment signature to receive the JSON result.
For marketplaces that handle billing themselves, PAL exposes a separate machine-readable OpenAPI definition with catalog audit, catalog remediation, GTIN validation, feed diff and x402 declaration validation operations.
No Shopify login, Merchant Center token, customer data, order data or private key is required. PAL operates on the catalog/feed records you submit. Results are deterministic technical guidance and do not guarantee Merchant Center approval or regulatory compliance.
The production API is published in the Official MCP Registry as io.github.enricoaboujaoude-droid/pal-commerce-catalog-intelligence and exposes a remote Streamable HTTP MCP server at /mcp. The free MCP tool recommend_catalog_offer routes buyers across the $1, $5, and $20 remediation tiers before payment.
