answers 402

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.

We sent a real POST request to this endpoint and it answered 402 with payment requirements we could parse.
