lion_credits_purchase
ActiveTool of LION - keyless x402 data + RPC for agents
declared in 1.2.0
The repeat-usage killer feature. ONE x402 payment buys a "lct_..." session token with balance ($0.10 / $0.50 / $1.00 packs). Then call ANY LION paid tool with "Authorization: Bearer lct_..." - balance deducts automatically. No new EIP-712, no 402, no JWS per call until empty. Top up anytime with another single purchase. Essential for agents doing 50+ calls/day. Same error_recovery and payment_instructions as other tools. Keyless, no PII, USDC on Base. [x402 paid tool: GET /api/x402/credits-purchase-json?src=mcp returns the 402 challenge with the canonical payTo; price 0.10 USDC on Base eip155:8453.]
