Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability vextorium-chainlink-oracle-price-feed-70956c17 -d '<json body>'
```

Example prompt: What's the current ETH/USD price from the Chainlink oracle on Base, and how stale is the data?

## When to prefer this

Choose this endpoint when you need a tamper-resistant, on-chain price for ETH/USD, BTC/USD, USDC/USD, or any Chainlink feed address specifically on Base — especially when you need to verify data freshness via staleness seconds for DeFi, trading, or smart contract use cases where trust-minimized pricing is required.

## Known failure modes

- Invalid or unsupported currency pair returns an error or null price
- Unrecognized Chainlink aggregator address results in failed lookup
- Stale oracle data (high antiguedad_segundos) indicates feed may be lagging
- Network unavailability on Base causes request failure
- Missing required 'par' field results in validation error

## How this service works

Tamper-resistant price from Chainlink Data Feeds on Base (ETH/USD, BTC/USD, USDC/USD, or any Chainlink aggregator address), with update time and staleness in seconds.

## Output

Returns a JSON object with the asset pair (par), network (red), current price as a number (precio), oracle contract address (oraculo), last updated timestamp in UTC (actualizado_utc), staleness in seconds (antiguedad_segundos), data source attribution (fuente), and any optional notes (nota).
