Chainlink Functions Polygon Legacy · Dormant
Legacy EconomicHealth snapshot on Polygon via Chainlink Functions.
Legacy / dormant integration. FeedOracle previously used Chainlink Functions on Polygon for an EconomicHealth on-chain snapshot. Subscription 185 is currently dormant; the last confirmed on-chain update was 2026-03-12. The on-chain values described below reflect that last snapshot and are not updated live. Retained for historical transparency while Chainlink Functions sunsets in 2026.

uint256 health = oracle.economicHealth(); // e.g., 85

How It Works
The contract uses Chainlink Functions to fetch data from FeedOracle API:
// JavaScript executed in Chainlink DON
const url = "https://api.feedoracle.io/api/v1/macro/" + args[1];
const r = await Functions.makeHttpRequest({url});
return Functions.encodeUint256(r.data.value);
