Top up credits
Your first top-up generates your API key — no account, no email, one signature. The key works on every endpoint, and anyone can recharge any key.
Paying with Solana USDC? This page needs an EVM wallet, but the API accepts Solana — pay per call through the x402 flow or have your agent top up over MCP.
Your first top-up generates your API key and shows it exactly once — paying is how the key is created, there is no separate signup. Top up again from the same wallet and it simply refills the same balance (same key).

Agents top up programmatically — point yours at /skill.md. Prefer paying per call? Every endpoint also accepts raw x402 — no key needed at all.
