Credits & Tiers

Two rails, no subscription. Blue Chat runs on free daily credits — a bucket for everyone, bigger the moment you connect any wallet, topped up with USDC credit packs. Hub tools are pay-per-call in USDC on Base.

Blue Chat — credits

Every Blue Chat message spends credits. Start on the Guest tier with no wallet — connect any wallet (no token needed) and your daily allowance jumps to 500. Heavier modes (Web Search, Deep Think) spend more per message; your allowance is per day.

PacksUSDC on Base

Top up anytime · pay-per-credit

No token to hold, nothing to lock. Connect any wallet for the full daily allowance — need more than the daily bucket? Top up with a USDC credit pack on Base and it adds to a pool that carries over.

Hub tools — x402

The Hub's tools are billed per call in USDC on Base — no credits, no subscription, no API key. You pay only for the calls you make, at a price fixed per tool. These five core commands are the headline:

The full catalog spans from $0.01 per call. Browse every pay-per-call tool under x402 Tools.

No credits needed for tools

Chat credits and Hub payments are separate rails. Tools settle in USDC on Base via x402 (EIP-3009, Coinbase CDP facilitator) — you never spend chat credits on a tool call, and you never need credits or an API key to hit the endpoint.
