Pricing
You pay only for a scaffold that builds. A failed build is not charged. Connecting the MCP, browsing the catalog and calling get_help are free.
With an account: credits
One scaffold = 100 credits. Sign in once with MCP OAuth (or send your account API key as the connection's Authorization header).
- Spark — 100 credits · $9 (1 scaffold)
- Builder — 500 credits · $39 (5 scaffolds)
- Studio — 2000 credits · $129 (20 scaffolds)
No account: x402
0.5 USDC on Base per scaffold. Your agent calls purchase_scaffold without signing in, gets an HTTP 402 with the payment details, pays, and retries. Settled only if the build succeeds.
Before sending funds, check /pay.json — it says whether wallet payment is switched on right now.
