Technical details
Endpoint
GEThttps://changelog-state-api.replit.app/api/monitors/viem/changes?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need historical or recent change events for the viem vendor specifically, including fine-grained filtering by change type (breaking signals, version bumps, etc.) or time window. Prefer this over a general releases endpoint when you care about the detection timeline rather than just the latest structured release data.
Side effects
- Invalid or unrecognized vendor slug returns empty results or 404
- 'since' timestamp in wrong format causes validation error
- Requesting more than 200 items via 'limit' is rejected
- Paid endpoint — missing or invalid x402 payment header results in 402 Payment Required
- Network timeout if Replit host is cold-starting
