How this service works
Deterministic analysis APIs and MCP tools: supplier price list comparison, PDF table extraction, product feed validation, product data mapping.
Output
A JSON object containing a structured comparison result with all detected differences between the two price lists, a success status, and a confidence level (e.g. 'high') indicating how reliably the files were parsed and matched.
Example use cases
Detect supplier price increases before re-ordering
“My supplier just sent a new price list — here's the old one: https://storage.example.com/acme_prices_jan.csv and the new one: https://storage.example.com/acme_prices_feb.csv. Can you compare them and flag everything that got more expensive?”
Validate PDF price list against last XLSX version
“I received an updated supplier catalog as a PDF at https://files.example.com/catalog_2024.pdf — compare it to the previous Excel version at https://files.example.com/catalog_2023.xlsx and show me any price or product differences with confidence scores.”
Automate weekly supplier price monitoring
“Every week I get a new supplier price list dropped at https://erp.example.com/latest_prices.csv — compare it to last week's version at https://erp.example.com/prev_prices.csv and summarize which items changed price, were added, or were discontinued.”
Technical details
Endpoint
POSThttps://api.relaex-engineers.de/v1/supplier/compare?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a deterministic, structured comparison of two supplier price list files (CSV, XLSX, or PDF) and need reliable confidence scoring on the result. It is especially well-suited for procurement automation, ERP integration, and regular monitoring of supplier pricing changes without manual spreadsheet review. Prefer it over general-purpose document diffing tools when the context is specifically supplier or product pricing data.
Side effects
- Inaccessible URL — if either file URL is not publicly reachable, the request will fail with an error
- Unsupported file format — only CSV, XLSX, and PDF are supported; other formats will be rejected
- Unparseable file — highly irregular or scanned/image-only PDFs may yield low-confidence or empty results
- Mismatched schemas — if old and new files have very different column structures, matching confidence may be low
- Malformed options JSON — if the options field contains invalid JSON, the request will return an error
