API curl examples

Use the same connected wallet shown on this page as creator_wallet. Automated launch wallet mode is always enabled for new keys.

API root

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

1. Create a draft

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. Prepare create + first-buy transaction

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. Finalize after sending the signed transaction

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. Check draft status

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