How this service works
HALOWERK medienwerk — bezahlte Endpunkte nach x402. Preise in USDC auf Base Mainnet.
Output
A JSON object containing a structured diff between two cue-word coverage snapshots: lists of terms that gained coverage, lost coverage, or remained stable, along with frequency deltas, timestamps of both snapshots, and metadata about the media sources queried. Coverage is based on literal vocabulary matching only.
Example use cases
Seasonal product term shift detection
“Compare our baumarkt media cue-word coverage from February versus May — I want to see which seasonal hardware terms like 'Rasenmäher' or 'Gartenschlauch' spiked or dropped between those two snapshots.”
Competitor vocabulary monitoring
“Run a snapshot compare on the baumarkt media cue-word coverage to check whether competitor brand names appeared more or less frequently this quarter versus last quarter.”
Procurement language drift audit
“I need to see if procurement-related cue words in the hardware retail media changed between the Q1 and Q2 snapshots — compare the two and highlight any terms that shifted more than 20% in coverage.”
Technical details
Endpoint
POSThttps://medien.halowerk.com/v1/baumarkt/media/cue-word-coverage/snapshot-compare?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to compare literal vocabulary coverage between exactly two discrete baumarkt (hardware/DIY retail) media snapshots over time — particularly when tracking terminology drift, seasonal keyword shifts, or procurement language changes. Prefer it over single-snapshot endpoints when a differential view (before/after) is required rather than an absolute coverage count.
Side effects
- Invalid or non-existent snapshot identifiers return an error indicating the snapshot was not found
- Snapshot timestamps outside the available data range return an out-of-bounds error
- Missing required comparison target or baseline parameters return a 400-level validation error
- Payment failure via x402 results in a 402 Payment Required response before processing
- Empty cue-word list or malformed query returns a descriptive validation error
