Images
Any coin as SVG at /coin/N.svg, as a 1024 pixel PNG at /coin/N-1024.png, and as a 1200 by 630 link card at /coin/N.png. The same coin at any yield level at /coin/N.svg?yield=BPS, any seed at /preview/HEX.svg, and each Master Coin with a sample seed at /master/I.svg. The SVG is the same file the contract holds: a 64 by 64 grid, one path per colour. Render it with image-rendering: pixelated so the pixels stay square.

Data
/api/state gives the series, the supply, the Master Coins left and the newest coins. /api/coin/N returns one coin: seed, fingerprint, traits, rarity, backing, yield, holder, image links. /api/holder/ADDRESS lists one wallet's coins. /spec.json holds the trait tables with their odds, the yield levels, the 50 Master Coin names and modes, and the backing classes 10, 25, 50, so you can port the generator. Every answer carries a chain block that says how old the numbers are. All JSON, open to any origin. The metadata a marketplace reads comes from the contract's own tokenURI, not from here.
