A read-only reference for gold coins: the catalogue (issuers, series, types,
issues, mints), the gold spot price and the rate table that prices melt value
with it. The base URL is https://api.restrike.co/v1, and everything in this
section is rendered from the same OpenAPI document
the API serves.
The catalogue, spot and rates endpoints are public: no key, no account, no
Authorization header. The quickstart is the five-minute
tour; the contract around the endpoints is on versioning,
rate limits and errors.
