Coin snapshot on a date

Price, market cap and 24h volume of a coin on ONE past date (00:00 UTC snapshot), in every currency at once plus your chosen one called out. Pass `date` (YYYY-MM-DD) or `daysAgo` (1-365). The point-in-time sibling of crypto-history (which returns a series): use it to value a position as of a date, compute a since-date return, or check a tax-lot basis. Historical range on this plan is the past 365 days, enforced before the call. Cached in-process for 5 minutes.

The response is HTTP 402 Payment Required with exact payment requirements. Any x402 v2 client pays automatically and retries:
