Live rates endpoint

JSON, CORS open, cached about 60 seconds. Two different figures travel in this payload, so read the field names rather than the first number you find.

payout is the rate Yesa actually pays a seller: this is what you receive when you sell, and it is the figure to quote. market (and the top level usdNgn and coins[].ngn, kept for existing readers) is the underlying market feed Yesa prices from. It is indicative, and nobody receives it. payout.tiers covers larger sells, and payout.prev is roughly 24 hours old, for day-on-day comparison. The payout block is absent, never zero, when a rate cannot be computed.
