How this service works
Detected changelog update history for one tracked vendor.
Output
A JSON array of detected changelog change records for the xAI vendor, each containing fields such as change type (e.g. new_release, version_changed, date_changed, title_changed, breaking_signal), detection timestamp, and diff/event details. Results can be filtered by type and time range, with up to 200 records per call.
Example use cases
Detect recent xAI breaking changes
“Have there been any breaking changes or breaking signals in xAI's changelog in the past 30 days? Show me up to 100 results.”
Track xAI version releases over time
“I want to see all version_changed events for xAI since October 2024 — pull the full list from the changelog history.”
Stay informed on xAI new releases
“What new releases has xAI shipped? Give me the most recent 20 new_release events from their changelog history.”
Technical details
Endpoint
GEThttps://changelog-state-api.replit.app/api/monitors/xai/changes?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a structured history of detected changelog changes for xAI specifically — particularly when you want to filter by change type (e.g. only breaking signals or new releases) or query changes since a specific timestamp. Prefer this over generic web scraping or RSS feeds when you need machine-readable, typed change events with reliable detection timestamps.
Side effects
- Invalid or unrecognized vendor slug returns no data or an error
- Malformed since timestamp format causes a 400 bad request
- Limit exceeding 200 is rejected
- No changes found in the specified time window returns an empty array
- Service unavailability on Replit hosting may cause intermittent 5xx errors
- Payment failure via x402 protocol blocks access to the paid endpoint
