## 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 sitecheck-trade-energy-daily-crude-oil-prices-wti-brent-62022dd2
```

Example prompt: What are the current WTI and Brent crude oil spot prices, and can you pull the last 30 trading days of history so I can see how prices have been trending?

## When to prefer this

Choose this endpoint when you need authoritative daily WTI and/or Brent crude oil spot prices sourced directly from the EIA via FRED, especially when you need historical context (up to 60 trading days). Prefer this over web-scraping or financial data aggregators when EIA/FRED provenance is required. Not suitable if you need intraday/real-time crude futures prices, Cushing storage inventory data, or other petroleum products.

## Known failure modes

- Invalid 'days' parameter (outside 1–60 range) may return an error or default behavior
- FRED/EIA data may have a lag of 1–2 business days, so 'latest' may not reflect today
- Upstream FRED API unavailability could result in stale or missing data
- Network timeout from the Cloudflare Worker if FRED is slow to respond
- Payment failure (x402) if USDC balance is insufficient

## How this service works

Pay-per-call logistics, shipping, trade and energy data tools for AI agents, from official and public sources. Payment: x402, USDC on Base, Solana, Arc, Polygon, Arbitrum, Monad, World Chain, Optimism, Avalanche, Celo or Stellar, or RLUSD/XRP on the XRP Ledger. No signup, no API key; a failed call is not charged.

## Output

A JSON object containing two top-level keys — 'wti' and 'brent' — each with a 'unit' label, a 'latest' object (date + value in USD/barrel), and a 'history' array of date/value pairs covering the requested number of trading days. Also includes a 'source' URL pointing to FRED and a 'checkedAt' ISO timestamp indicating when the data was last fetched.
