Answers how stale each oracle price actually is on Base right now, and whether a standard consumer staleness guard would reject it. Reads Chainlink's aggregator proxy and Pyth's on-chain price for the same asset in the same block, and reports each feed's age against a per-feed bound derived from its own measured update cadence -- not one global threshold, because those cadences differ by more than an order of magnitude on the same chain (Chainlink's USDC/USD on Base runs a 24-hour heartbeat by design, while ETH/USD updates in minutes). Why pay instead of reading it yourself: the trap is not fetching a price, it is knowing which address is the real proxy (a raw aggregator answers description() identically and then silently freezes when Chainlink rotates it) and what 'stale' means for that specific feed. The Chainlink-vs-Pyth spread is included, but always next to Pyth's own confidence interval, so a difference inside the oracle's stated uncertainty is not mistaken for disagreement. Optional assets query parameter; all supported assets by default.
