    Helium is a fundraising-research REST API sharing Horizon's prepaid-credit
    account system. Every request authenticates with an `Authorization: Bearer
    <key>` header (the same key that works against Horizon) and, on a billed
    endpoint, debits a fixed number of credits from your shared prepaid balance.
    Check your balance any time with GET /v1/usage (shared with Horizon).
