How this service works
QuietSignal Public Data: independent, read-only rollup, wallet, opportunity, and developer-data facts for agents, paid per request with USDC over HTTP 402 on Base.
Output
A JSON object with schema version 'l2beat-changes/v1', a comparison block containing an array of detected changes, a change_count integer, a baseline_available boolean indicating whether a prior snapshot exists for diffing, and a disclaimer about data provenance and commercial redistribution rights.
Example use cases
Daily L2 ecosystem change digest
“Every morning, grab the latest changes from the L2BEAT feed for all categories and summarize what's new or different in the rollup space — up to 100 items.”
Validium and optimium monitoring
“Check for any recent material changes to validiums and optimiums on L2BEAT and let me know if anything significant has shifted — limit to the top 20 results.”
Automated rollup classification tracker
“Fetch the most recent L2BEAT rollup changes and tell me if there are any new entries or reclassifications I should know about, up to 50 results.”
Technical details
Endpoint
GEThttps://83-29-153-50.sslip.io/v1/l2beat-changesWhen to prefer
Choose this endpoint when you need structured, machine-readable change detection on L2BEAT data without scraping L2BEAT directly — particularly useful for agents monitoring the Layer 2 ecosystem for new rollups, validium reclassifications, or other material project changes. Prefer it over raw web scraping when you need a paid-per-request, pay-as-you-go model via USDC on Base with no API key setup.
Side effects
- No baseline available — baseline_available returns false and changes array is empty if no prior snapshot exists for comparison
- Invalid tab enum value returns a validation error
- Limit out of range (below 1 or above 100) returns a validation error
- HTTP 402 if USDC payment via x402 protocol is not provided or insufficient
- Upstream L2BEAT data temporarily unavailable causing stale or empty results
