Tool role
Current state
Browser-only feed tester. It calls decimals() and latestRoundData() via the RPC URL you provide.
Limitations
RPC CORS can block requests. This page does not yet maintain server-owned feed freshness or historical feed observations.
Next paid-plan step
Move common checks to a same-origin API, return normalized status, and store only bounded compact feed checks.
Inputs
JSON-RPC URL
Feed Contract Address
Result
Implementation path
- Normalize feed result into
fresh / stale / degraded / unavailable. - Expose a same-origin
/api/oracles/*route for known feeds. - Keep only compact bounded history after the API contract is stable.
