## Markets

| Endpoint                                                            | Returns                                               |
| ------------------------------------------------------------------- | ----------------------------------------------------- |
| [`GET /bridge/source-chains`](/api-reference/markets/source-chains) | Every chain a transfer can start from.                |
| [`GET /bridge/routes`](/api-reference/markets/routes)               | Which venues serve a corridor, and with which assets. |
| [`GET /bridge/venues`](/api-reference/markets/venues)               | Every venue, whether it is on, and what it can sign.  |

## Transfers

| Endpoint                                                            | Does                                                                                            |

| [`POST /bridge/quote`](/api-reference/quote/quote)                  | Prices the transfer across every venue. Returns `best`, `bestByTime` and the full ranked table. |

| [`POST /bridge/transfers/{id}/submit`](/api-reference/quote/submit) | Takes the signed transaction, or the hash of one you already sent.                              |
| [`GET /bridge/transfers/{id}`](/api-reference/quote/transfer)       | The transfer's status until it is delivered.                                                    |

Hyperliquid is a destination chain like any other: `toChain: "hypercore"`. See [Hyperliquid](/concepts/hyperliquid).

The OpenAPI 3.1 document is at [`/v1/openapi.json`](https://api.bridg.now/v1/openapi.json). The [TypeScript SDK](/sdk) wraps these seven calls.
