## 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 lumi-sealed-btc-forecast-history-94f4b9bc -d '<json body>'
```

Example prompt: Pull the last 50 sealed BTC forecast history rounds from LUMI so I can benchmark the agents' prediction accuracy against the settled prices.

## When to prefer this

Choose this endpoint when you need immutable, sealed historical BTC forecast data that cannot be backfilled — specifically for benchmarking forecasting models or evaluating multi-agent prediction accuracy. Prefer this over live trading signals or general market data APIs when the goal is reproducible research or model evaluation using cryptographically anchored historical rounds.

## Known failure modes

- Invalid offering identifier (must be exactly 'forecast_history') returns an error
- Limit out of range (below 1 or above 200) returns a validation error
- Payment not provided or insufficient USDC triggers a 402 Payment Required response
- Network or server errors may return 5xx responses

## How this service works

Sealed Forecast History. Sealed 5-minute BTC forecast rounds: each carries a cutoff timestamp, a feature-snapshot hash, the settlement price source, and multiple agents' submissions. Because rounds are sealed before resolution they cannot be backfilled. A dataset for benchmarking, not a trading signal.

## Output

A list of sealed 5-minute BTC forecast rounds (up to 200), each containing: a cutoff timestamp marking when the round was sealed, a feature-snapshot hash ensuring immutability, the settlement price source used for resolution, and the multiple agents' forecast submissions for that round. Because rounds are sealed before resolution, the dataset is tamper-evident and suitable for benchmarking.
