Prepaid API credits and API key for clients that cannot sign an x402 payment per call (most MCP clients): one payment buys credit ($5, $20 = $22 credit, $50 = $60) and returns an API key. Send it as X-API-Key on any paid route or MCP tool; each call costs its x402 price and failed calls are refunded. With your key in X-API-Key it tops that key up.
