Oracle Feed Tester

Browser-side AggregatorV3 feed check for World Chain builders.

Current mode: browser-only RPC call helper. Paid-plan path: same-origin feed metadata, freshness checks, and bounded test history.

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.
