How this service works
A simple, fully disclosed momentum signal from Chainlink on Base: current price versus the price 24 oracle rounds earlier, percent change, and a label (up / down / flat, threshold 0.5%). Pass ?pair=ETH-USD (default). The method is the whole product: no model, no secret sauce. Not financial advice.
Output
Returns the current Chainlink oracle price for the requested pair, the price from 24 oracle rounds earlier, the percent change between them, and a directional label: 'up', 'down', or 'flat' (using a 0.5% threshold). The methodology is fully disclosed — no proprietary model is involved.
Example use cases
Pre-trade momentum check for ETH
“Before I place a trade, can you check the current Chainlink momentum signal for ETH-USD and tell me whether it's up, down, or flat and by how much?”
BTC trend alert for trading bot
“Is BTC-USD showing upward momentum right now based on Chainlink oracle data on Base — what's the percent change and the signal label?”
Dashboard signal refresh for crypto portfolio
“Refresh the momentum signal for ETH-USD from the Chainlink oracle — I want the current price, the price 24 rounds ago, the percent change, and whether it's labeled up, down, or flat.”

Endpoint
GEThttps://oraclepost.higgsfield.app/api/signalWhen to prefer
Choose this endpoint when you need a transparent, fully disclosed momentum signal derived purely from on-chain Chainlink oracle data on Base — no black-box model, no secret sauce. Prefer it over proprietary signal APIs when auditability and simplicity matter. It is purpose-built for lightweight agent workflows that need a quick directional label without complex ML infrastructure.
Side effects

- Chainlink oracle on Base is temporarily unavailable or lagging, causing stale or missing data
- Payment of $0.001 USDC not completed (x402 payment required error)
- Network issues reaching the Base RPC or oracle contract
