## [1.0.0] - 2026-07-22



### Added



- Initial release, ported from the reference `mercury-go` SDK.

- `Mercury.Client` — Req-based transport with configurable timeout, retry,

  base URL, and request/response hooks.

  `Mercury.NotFoundError`, `Mercury.ValidationError`,

  `Mercury.ConflictError`, `Mercury.RateLimitError`, `Mercury.ServerError`,

  `Mercury.NetworkError`, `Mercury.TimeoutError`, and `Mercury.Error`

  classification predicates.

- Lazy, auto-paginating `Stream`s via `Mercury.Pagination` on every list

  endpoint.

- Full resource coverage: `Mercury.Accounts`, `Mercury.Transactions`,

  `Mercury.Recipients`, `Mercury.Invoices`, `Mercury.Payments`,

  `Mercury.Categories`, `Mercury.Customers`, `Mercury.Treasury`,

  `Mercury.Webhooks` (including inbound signature verification),

  `Mercury.Events`, `Mercury.Organization`, `Mercury.Users`,

  `Mercury.SafeRequests`, `Mercury.Credit`, `Mercury.Attachments`,

  `Mercury.OAuth2`.

- `!`-suffixed raising variant for every function.
