POST /tx

Simple REST endpoint for submitting a single signed transaction. Alternative to the JSON-RPC sendTransaction method — same routing logic, simpler request format.

Servers

Region	Endpoint
Frankfurt	`https://fra.send.raze.sh/tx`
Amsterdam	`https://ams.send.raze.sh/tx`
Chicago	`https://chi.send.raze.sh/tx`
Singapore	`https://sg.send.raze.sh/tx`

Request

POST /tx
Content-Type: application/json

{
  "transaction": "<encoded_signed_transaction>",
  "encoding": "base64"
}

Field	Type	Required	Default	Description
`transaction`	string	Yes	—	Signed transaction, base64 or base58 encoded
`encoding`	string	No	`"base64"`	`"base64"` or `"base58"`

Response

Success:

{
  "success": true,
  "signature": "5KtPn1LGuxhFiwjxqLHpBCa6xjnB7YaB1pPB263DezXAZ8z7Pnrn..."
}

Error:

{
  "success": false,
  "error": "tip below minimum (0.0001 SOL)"
}

HTTP Status	Meaning
`200`	Transaction accepted and routed
`400`	Decode failure or tip below minimum

Routing

Transactions are routed based on tip amount (same as JSON-RPC):

Tip	Channels
< 0.0001 SOL	Rejected
0.0001 – 0.001 SOL	QUIC TPU
0.001 – 0.01 SOL	QUIC TPU + RPC
≥ 0.01 SOL	QUIC TPU + RPC + SWQoS + Jito
