How this service works
Compare Timestamped source search for competition wording; literal vocabulary only. against a bounded caller-supplied previous snapshot and return exact change witnesses. Baseline is caller supplied and is never authenticated as historical server output. Pure bounded timing/source-quote validation runs before payment. Exactly one current motor call, zero baseline provider calls. Full current provider disclosure retained; baseline is not submitted to the provider.
Output
A JSON object containing the current fetched source text with timestamp, a set of exact change witnesses (literal word/phrase-level diffs) between the current fetch and the caller-supplied baseline snapshot, and full disclosure of the current provider source. The baseline is not forwarded to the provider.
Example use cases
Weekly competitor promo text audit
“Compare today's sales copy from this hardware store competitor against the snapshot I captured seven days ago and show me every exact word or phrase that was added, changed, or removed.”
Pre-campaign wording validation
“Before we launch our campaign, pull the current literal wording from this competitor's media listing and diff it against the baseline snapshot I'm sending — I need to know if they already changed their pricing language.”
Dispute-ready change evidence
“I need documented proof of exactly what wording this competitor used to have versus what they show now — run the snapshot compare on this Baumarkt media source and give me the precise change witnesses with timestamps.”

Endpoint
POSThttps://medien.halowerk.com/v1/baumarkt/media/sales-competitor-literal-index/snapshot-compare?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need exact, literal word-for-word change detection in competitor sales or media copy — specifically in the Baumarkt/hardware retail domain — and you already hold a prior snapshot you want to diff against. It is ideal when evidence-grade, quote-exact change witnesses are required (e.g. for compliance, dispute, or campaign planning) rather than a semantic or summarized comparison. Prefer this over generic web-diff tools when you need the current provider source fully disclosed and the baseline kept private from the provider.
Side effects
- Invalid or unreachable competitor source URL returns an error with no diff output
- Malformed or missing baseline snapshot in request body causes validation failure
- Source content has not changed, returning empty change witnesses
- Payment not confirmed via x402 before call execution results in rejection
- Rate limits or provider-side blocking of the target URL cause fetch failure
