 # Solana: Jito Bundles and Transactions
 
 [Jito bundles](/docs/chains/solana/solana-jito-bundles-and-transactions) are groups of up to 5 signed transactions that execute sequentially and atomically in a single slot on Solana Mainnet. A tip to one of the Jito tip accounts is required for inclusion. These methods are available on paid Alchemy plans only.

+subtitle: Alchemy's REST endpoints for pricing and building Solana token swaps.

+
+## Background
+
+The Solana Trader API returns swap quotes and, on request, an assembled
+transaction that a taker can sign and broadcast. Use it to price a swap ahead
+of time, present a route to a user, or hand a signable transaction to a
+wallet. Requests use the same Alchemy API key as your other Solana calls.
+
+Alchemy routes Trader API requests through [Metis](https://station.jup.ag/blog/jupiter-swap-v2-metis), the routing engine that powers Jupiter's Swap V2 `/order` endpoint. If you have already integrated Jupiter's contract, the response shape here will feel familiar. Two differences worth calling out:
+
+* Alchemy carries auth in the URL path (see [Endpoint](#endpoint)), not in an `x-api-key` header.
+* `/quote-multiple-output-mints` is an Alchemy-specific endpoint that returns quotes for one input mint against up to 32 candidate output mints in a single request.
+
+The API exposes three endpoints:
+
+* `GET /order` returns a swap quote. Pass a `taker` to also receive an unsigned base64 transaction; omit `taker` for a quote-only response.
+* `GET /build` returns raw swap instructions for composing into your own transaction (multi-leg flows, program deposits, cleanup steps).
+* `POST /quote-multiple-output-mints` returns quotes for a single input against up to 32 output mints in one call.
+
+## Endpoint
+
+Solana Trader API is available on **Solana Mainnet** through the standard Alchemy Solana endpoint. Devnet is not supported.
+
+```text
+https://solana-mainnet.g.alchemy.com/v2/{apiKey}
+```
+
+Use your Solana Mainnet API key from the [Alchemy Dashboard](https://dashboard.alchemy.com/apps). The `docs-demo` key powers the Try It widget on the method pages below.
+
+## Methods
+
+| Method | Function | CU cost | Throughput CUs (how many CUs this will count for towards your CUs per second capacity) |
+| --- | --- | --- | --- |
+| [GET /order](/docs/chains/solana/solana-trader-api/solana-trader-api/get-swap-order) | Get a swap quote. Include a `taker` to also receive an unsigned base64 transaction; omit `taker` for quote fields only. | 100 | 100 |
+| [GET /build](/docs/chains/solana/solana-trader-api/solana-trader-api/build-swap-instructions) | Return raw swap instructions for composing into your own transaction. | 100 | 100 |
+| [POST /quote-multiple-output-mints](/docs/chains/solana/solana-trader-api/solana-trader-api/quote-multiple-output-mints) | Quote a single input mint against up to 32 candidate output mints in one call. | 100 | 100 |
