How this service works
Get official TED Change Notices with lot-level deltas or an explicit metadata-only status
Output
Returns a list of official TED change notice records, each containing lot-level field deltas showing what changed between versions, or a metadata-only status indicator when content comparison was not performed. Results include computed change event labels (e.g. deadline_changed), verification status, and associated procurement signals for each notice.
Example use cases
Deadline change monitoring for procurement team
“Pull the latest TED change notices for Spanish tenders where a deadline_changed event was detected — I want verified field deltas only, up to 10 results.”
Italian tender specification drift detection
“Get me up to 15 TED change notices for Italy with a verification status of verified_field_delta so I can see exactly what fields changed in each lot.”
Metadata-only change audit for compliance review
“Fetch TED change notices flagged as official_change_metadata_only for Germany — I need to audit which notices had changes recorded but content wasn't compared, up to 50 results.”
Technical details
Endpoint
GEThttps://tenderdelta-preview.mooncakemonkey1.workers.dev/x402/v1/verified-changesWhen to prefer
Use this endpoint when you need to track what specifically changed in EU public tender notices at the lot level — especially for Germany, Spain, or Italy — and want verified, structured field deltas rather than raw document diffs. Prefer it over generic TED search when your goal is change detection or procurement monitoring workflows rather than initial tender discovery.
