## How to call it through Zero

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

```sh
zero fetch --capability pocket-network-chainlink-price-feed-oracle-6852b106 -d '<json body>'
```

Example prompt: What's the current ETH/USD price from the Chainlink oracle on Ethereum mainnet? I also need the feed address and when it was last updated.

## When to prefer this

Choose this endpoint when you need on-chain Chainlink oracle prices for ETH/USD, BTC/USD, or MATIC/USD without requiring an API key or account — ideal for permissionless, pay-per-use agent workflows where decentralized price provenance matters. Prefer over centralized exchange price APIs when DeFi-grade oracle data with a verifiable feed address is needed.

## Known failure modes

- 400 Bad Request if an unsupported pair is requested (anything other than ETH/USD, BTC/USD, MATIC/USD)
- 400 Bad Request if chain_id does not match the pair (e.g. MATIC/USD with chain_id 1)
- 402 Payment Required if USDC payment is not provided
- Stale data if the underlying Chainlink feed has not been updated recently
- Network errors if Pocket Network RPC nodes are unavailable

## How this service works

Chainlink price feed reads for three pairs: ETH/USD and BTC/USD on Ethereum (chain 1) and MATIC/USD on Polygon (chain 137). POST /v1/price with {pair, chain_id} and get the latest answer, feed address and update time. Any other pair answers 400. Pay per request in USDC; no account, no API key.

## Output

Returns the latest Chainlink oracle price answer (as a raw integer with decimals), the on-chain feed contract address, and the timestamp of the last price update for the requested pair and chain.
