# Crycket Documentation

## Docs

- [Build transaction](https://docs.crycketpay.com/api-reference/endpoint/build.md): Builds the unsigned transaction for a Payment Intent. Performs ATA check (Solana), constructs memo, resolves fee token (Tempo). Returns a chain-agnostic blob ready for `wallet.signTransaction()`.
- [Create intent](https://docs.crycketpay.com/api-reference/endpoint/create.md): Creates a new Payment Intent. The same `idempotencyKey` within 24 hours returns the existing Intent with `X-Idempotent-Replayed: true`.
- [Cancel intent](https://docs.crycketpay.com/api-reference/endpoint/delete.md): Cancels a Payment Intent. Only possible when the intent is in `created` state (before any transaction has been submitted).
- [Mark detected](https://docs.crycketpay.com/api-reference/endpoint/detected.md): Signals that the fulfiller has received the audio broadcast and acknowledged the payment request. Updates the `detectedAt` timestamp on the intent.
- [Get intent](https://docs.crycketpay.com/api-reference/endpoint/get.md): Retrieves a Payment Intent by its ID. Served from cache (60s TTL, refreshed on each state change).
- [List chains](https://docs.crycketpay.com/api-reference/endpoint/get-chains.md): Returns all supported chains with their configuration, including confirmation strategy, block times, and polling schedules.
- [List tokens](https://docs.crycketpay.com/api-reference/endpoint/get-tokens.md): Returns all supported tokens, optionally filtered by chain. Includes canonical symbols and chain-specific contract addresses.
- [List intents](https://docs.crycketpay.com/api-reference/endpoint/list.md): Returns a paginated list of Payment Intents for your account. Filterable by state, chain, and date range.
- [List webhook deliveries](https://docs.crycketpay.com/api-reference/endpoint/list-webhooks.md): Returns recent webhook delivery attempts for your account, including status and retry count.
- [Create refund](https://docs.crycketpay.com/api-reference/endpoint/refund.md): Creates a linked refund Payment Intent for a confirmed or finalized intent. The refund intent goes through the same lifecycle as a regular intent.
- [Retry webhook](https://docs.crycketpay.com/api-reference/endpoint/retry-webhook.md): Replays a webhook delivery. Useful for recovering from temporary endpoint failures.
- [Simulate transition](https://docs.crycketpay.com/api-reference/endpoint/simulate.md): Forces a state transition on a Payment Intent for integration testing. Only available in test mode (`pk_test_` keys).
- [Stream status](https://docs.crycketpay.com/api-reference/endpoint/stream.md): Opens a Server-Sent Events (SSE) stream for real-time status updates on a Payment Intent. The stream emits events on every state transition.
- [Submit transaction](https://docs.crycketpay.com/api-reference/endpoint/submit.md): Accepts a signed transaction blob. Broadcasts to chain via the RPC proxy. Transitions state to `pending`. Idempotent on tx signature/hash.
- [Update intent](https://docs.crycketpay.com/api-reference/endpoint/update.md): Updates a Payment Intent (e.g. to attach a fulfiller). The caller must supply the current `updatedAt` timestamp; stale writes return `409`.
