POST /service
Continuous smart-contract monitoring and change detection. Instead of re-buying the same one-off verdict every day, this watch returns the CURRENT security verdict PLUS exactly what changed since the last time this contract was checked: owner changed or ownership taken back, proxy implementation/beacon upgraded (logic swap), proxy-admin changed, verification (Sourcify) gained or lost, honeypot or buy/sell tax flip, new dangerous functions (mintable, pausable, blacklist, selfdestruct, hidden owner), trust-list on/off, and verdict escalation. Use it for continuous contract monitoring, upgrade/rug watch, security drift detection and change alerts. Built on the same on-chain engine (web3 proxy/owner reads + Sourcify + GoPlus token & address security). Ed25519-signed. 0.02 USDC on Base.

HEAD https://contractwatch.hergertsynthora.com/ returned 402.

The registry record was observed and retained with provenance.
EVIDENCE
Each record has an exact-route quote outcome. Unresolved templates and potentially mutating methods are labeled instead of being invoked without provider-specific test input. A quote is still separate from a settled paid call.
