- [Authentication](https://docs.paycrest.io/api-reference/authentication.md)
- [Errors](https://docs.paycrest.io/api-reference/errors.md)
- [Initiate Order](https://docs.paycrest.io/api-reference/sender/initiate-payment-order-v2.md): Creates a new payment order.
- [List Orders](https://docs.paycrest.io/api-reference/sender/list-payment-orders-v2.md)
- [Get Order by ID](https://docs.paycrest.io/api-reference/sender/get-payment-order-by-id-v2.md)
- [Get Sender Stats](https://docs.paycrest.io/api-reference/sender/get-sender-stats.md)
- [List Webhook Deliveries](https://docs.paycrest.io/api-reference/sender/list-webhook-deliveries.md): Returns the authenticated sender's webhook delivery log, newest first. Use this to audit which events were delivered and to find failed or expired deliveries to replay. List items omit the large `requestPayload` and `responseBody` fields — fetch a single delivery to see them.
- [Get Webhook Delivery](https://docs.paycrest.io/api-reference/sender/get-webhook-delivery-by-id.md): Returns a single webhook delivery, including the frozen `requestPayload` and the captured `responseBody`. Returns `404` if the delivery belongs to another sender.
- [Retry Webhook Delivery](https://docs.paycrest.io/api-reference/sender/retry-webhook-delivery.md): Replays a webhook delivery using its original frozen payload.
- [List Orders](https://docs.paycrest.io/api-reference/provider/list-orders-v2.md): Returns a paginated list of payment orders assigned to the authenticated provider, in the v2 response schema. Requires a `currency` query parameter. Supports optional `direction` (`onramp` / `offramp`), `search`, `export=csv`, `from`/`to` date filters, and `ordering` (asc/desc).
- [Get Order by ID](https://docs.paycrest.io/api-reference/provider/get-order-by-id-v2.md): Returns a single payment order assigned to the authenticated provider, including polymorphic source/destination, providerAccount, and transaction logs.

- [Get Token Rate](https://docs.paycrest.io/api-reference/general/get-token-rate.md): Public quote on a specific network. Returns **buy** and/or **sell** quotes, order type, and refund timeout.
- [Get Markets](https://docs.paycrest.io/api-reference/general/get-markets.md): Returns the live protocol orderbook (all funded, available provider quotes across corridors × tokens × networks) plus network-wide aggregate statistics.
- [Get Aggregator Public Key](https://docs.paycrest.io/api-reference/general/get-aggregator-public-key.md)
- [Verify Account](https://docs.paycrest.io/api-reference/general/verify-account.md): Resolves the account holder name when available. For some fiat corridors (e.g. KES M-Pesa), `data` may be `"OK"` when the account is valid but no display name is returned — supply your own `accountName` on the order in that case.
- [Get Order Status by Gateway ID](https://docs.paycrest.io/api-reference/sender/get-lock-payment-order-status.md): Retrieve the status of an order by its onchain Gateway ID and chain ID. Use this for smart contract integrations.
