HALOWERK medienwerk — bezahlte Endpunkte nach x402. Preise in USDC auf Base Mainnet.
Output
A JSON object containing the diff between two literal keyword index snapshots for the specified marketing campaign, including added keywords, removed keywords, and any modified entries, along with metadata about both snapshots such as timestamps and campaign identifiers.
Example use cases
Detecting campaign keyword drift over time
“I need to know what literal keywords changed in our 'BlackFriday2024' marketing campaign index between last week's snapshot and today's — can you pull a comparison and highlight anything that was added or dropped?”
Auditing campaign index before a product launch
“Before we go live with the 'SpringCollection' campaign, compare the pre-launch keyword index snapshot against the current one and flag any unexpected changes in the literal vocabulary.”
Compliance review of campaign content changes
“Our compliance team needs a side-by-side diff of the 'HealthPromo' campaign's literal keyword index from the snapshot taken on March 1st versus the one from March 15th — what shifted between those two dates?”

- One or both snapshot references not found results in a not-found error
