Your Solana API key

你的 API 密钥

Setiap aplikasi sebaiknya memakai kunci sendiri. Tinjau status, origin, dompet peluncuran, dan nonaktifkan kunci bocor atau tidak terpakai dengan cepat.

连接钱包以查看密钥。

API curl 示例

使用本页显示的同一个已连接钱包作为 creator_wallet。新密钥始终启用自动发布钱包模式。

API 根路径

curl -sS https://launchpad.meme/api/v1

1. 创建草稿

API_KEY="lp_live_..."
LAUNCH_WALLET="YOUR_CONNECTED_WALLET"

curl -sS -X POST https://launchpad.meme/api/v1/coins/create-draft \
  -H "Authorization: Bearer ${API_KEY}" \
  -H "Content-Type: application/json" \
  -d "{
    \"chain\":\"solana\",
    \"token_standard\":\"token_2022\",
    \"creator_wallet\":\"${LAUNCH_WALLET}\",
    \"name\":\"Example Coin\",
    \"symbol\":\"EXAMPLE\",
    \"description\":\"Created through launchpad.meme API.\",
    \"image_url\":\"https://example.com/logo.webp\",
    \"initial_buy_sol\":\"0.01\",
    \"slippage\":\"2\",
    \"priority_speed\":\"fast\"
  }"

Solana launch behavior: new drafts accept token_2022 only. When initial_buy_sol > 0, create-transaction returns transaction_base64; sign and submit it, then finalize with the confirmed tx_signature. When initial_buy_sol = 0, no blockchain transaction is built; finalize with the draft and transaction request IDs to publish an off-chain/pending coin page.

2. 准备创建 + 首购交易

curl -sS -X POST https://launchpad.meme/api/v1/coins/create-transaction \
  -H "Authorization: Bearer ${API_KEY}" \
  -H "Content-Type: application/json" \
  -d '{"draft_id":"draft_..."}'

3. 发送签名交易后完成

curl -sS -X POST https://launchpad.meme/api/v1/coins/finalize \
  -H "Authorization: Bearer ${API_KEY}" \
  -H "Content-Type: application/json" \
  -d '{
    "draft_id":"draft_...",
    "transaction_request_id":"txreq_...",
    "tx_signature":"REAL_SOLANA_SIGNATURE"
  }'

4. 检查草稿状态

curl -sS "https://launchpad.meme/api/v1/coins/status?draft_id=draft_..." \
  -H "Authorization: Bearer ${API_KEY}"
