Split USDC into Outcome Tokens

Endpoint

POST /ctf/split

Server: https://api.openfish.fun (port 3002)

Auth: L2 (API key required)

Tags: CTF

For every unit of USDC you split, you receive one unit of each outcome token in the market (e.g., 100 USDC yields 100 Yes + 100 No). The server debits your USDC balance, credits the outcome tokens, and — when running in on-chain mode — relays an ERC1155 split transaction.

Body

Field	Type	Required	Description
conditionId	string	Yes	Market condition ID (32-byte hex, 0x...)
amount	string	Yes	Amount of USDC to split, as a decimal string (6 decimals internally)

{
  "conditionId": "0xbd31dc8a...",
  "amount": "1000"
}

Response

200 — Split completed.

{
  "success": true,
  "conditionId": "0xbd31dc8a...",
  "amount": "1000",
  "tokens": ["1234...", "5678..."],
  "txHash": "0xabc..."
}

txHash is null when the server is running in off-chain settlement mode.

400 — conditionId and amount required or insufficient USDC: need X, have Y.
