# Shroomy Web3 Oracle – NFT/Crypto Floor Price Forecaster

> Shroomy Web3 Oracle – NFT/Crypto Floor Price Forecaster is a paid API for AI agents from oracle.the-undesirables.com, paid per call via x402, $0.05/call, status unknown (last checked 2026-09-15).

Fetches real-time NFT or crypto floor prices via Alchemy and runs 20,000-iteration Heston stochastic Monte Carlo simulations to produce probabilistic price forecasts across user-specified time horizons.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 oracle-the-undesirables-com-7b5f4f3f
```

Example prompt: Run a 30-day Heston Monte Carlo price forecast for the Bored Ape Yacht Club NFT collection (contract 0xBC4CA0EdA7647A8aB7C2061c2E118A18a936f13D) on eth-mainnet and give me the 5th, 50th, and 95th percentile price outcomes.

## When to prefer this

Use this endpoint when you need institutional-grade probabilistic price forecasting for a specific NFT collection or crypto asset on Ethereum mainnet (or other supported networks), combining live on-chain floor price data with rigorous stochastic volatility modeling. Prefer this over simple price lookups when you need a full distribution of outcomes (percentiles), not just a point estimate. Best for risk management, portfolio analysis, or investment decision support requiring Heston-model-based confidence intervals.

## Known failure modes

- Invalid or non-existent contract address returns error
- Unsupported network parameter causes failure
- Alchemy data unavailable for illiquid NFT collections with no floor price history
- Missing required query parameters (days, contract_address, network) returns bad request
- Rate limiting or upstream Alchemy API outage causes timeout

## How this service works

NFT collection floor-price oracle: fetches real-time floors via Alchemy and returns risk-aware price forecasts — current floor, historical volatility, drift, and forecast percentiles. Forecasting uses Merton Jump-Diffusion modeling for this crypto-native asset class. Supports any ERC-721 or ERC-1155 contract on Ethereum mainnet.

## Output

Returns current floor price in ETH, forecast percentile distribution (5th, 25th, 50th, 75th, 95th) over the requested time horizon, Heston model parameters used (drift, vol-of-vol, mean reversion, long-term variance), number of simulations run (20,000), network, contract address, and a status field. Priced at $0.05 USDC per call.
