# Send Transaction (GET)

> For the complete documentation index, see [llms.txt](/docs/llms.txt).

GET https://bitcoin-mainnet.g.alchemy.com/v2/{apiKey}/api/v2/sendtx/{hex}

Broadcasts a signed raw Bitcoin transaction encoded as a hex string in the path. Returns the transaction ID on success. The example value below is the hex of a confirmed Bitcoin transaction; re-sending it will respond with a Bitcoin-Core RPC error (e.g. `-25: bad-txns-inputs-missingorspent` once the inputs are spent, or `-27: transaction already in block chain` for unspent re-broadcasts). Substitute your own signed raw-transaction hex to broadcast. For larger payloads, use the POST variant.
