## 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`):

Example prompt: Pull me the full on-chain USO oil ETF snapshot from Realedger — I want to see every Uniswap pool ever created for it on Robinhood Chain, the current on-chain price vs the Chainlink print and the ETF's latest close, the gap between them, and whether NYSE was open when the price was read.

## When to prefer this

Choose this endpoint when you need a combined view of tokenized oil ETF (USO) activity on-chain alongside traditional market reference prices — specifically when you want Uniswap pool history, daily pool creation as a sentiment proxy, and the real-time on-chain vs Chainlink vs ETF close price comparison in a single call. Prefer it over generic DeFi explorers or commodity data APIs when the intersection of RWA tokenization, Robinhood Chain, and oil market sentiment is the focus.

## Known failure modes

- Robinhood Chain RPC unavailability causing stale or missing on-chain data
- Chainlink oracle feed delay or downtime leading to missing reference price
- NYSE calendar lookup failure causing null open/closed status
- Rate limiting or payment failure (x402) if USDC payment is not correctly attached
- Empty pool list if no Uniswap pools exist yet for this asset

## How this service works

Oil on Robinhood Chain at grade A: every Uniswap pool ever created against the tokenized USO oil ETF, dated by block and attributed to the launchpad that made it, pools per day as a retail oil sentiment series, plus the 24/7 on chain USO price against the Chainlink print and the ETF's dated close, with the gap and whether NYSE was open at the read. Full pool list included.

## Output

Returns a JSON payload containing: (1) a full list of every Uniswap pool ever created against the tokenized USO oil ETF on Robinhood Chain, each with block date and launchpad attribution; (2) a daily time series of pools-per-day as a retail oil sentiment indicator; (3) the current 24/7 on-chain USO price; (4) the corresponding Chainlink oracle price; (5) the ETF's most recent dated close; (6) the price gap between on-chain and ETF close; and (7) a flag indicating whether NYSE was open at the time of the on-chain read.
