Questions we hear most often — from developers wiring up an agent and from people reviewing the product.
Ulvane is built for AI agents, not humans filling out a signup form. x402 lets an agent pay per request in USDC and get an instant response — no signup flow an autonomous agent could actually complete on its own.
Payment goes through x402's "exact" scheme via Coinbase's own CDP facilitator — the same infrastructure Coinbase uses for its own x402 integrations. You pay only for the exact request you make; there's no subscription or stored balance that could be drained.
Base mainnet's own onchain data. Token names and symbols are read straight from the token contracts; swap history is read live from The Graph's Aerodrome, Uniswap v3 and Uniswap v4 subgraphs on Base (other DEXes aren't covered). PnL, risk, and trader rankings are computed directly from real swaps — not cached from a third-party score API.
It matches how an autonomous agent actually wants to consume a paid service: no human account-creation step, no key to leak or rotate, and cost that scales exactly with usage.
It means the token isn't on our hand-curated allowlist yet — not that it's unsafe. The allowlist only grows once we've manually confirmed an address against BaseScan or the project's own site.
Every response reflects a bounded recent-swap window (see each response's windowNote), not full history. A wallet or token with thousands of trades will show a partial picture until we move off the current free-tier data plan.
Base mainnet only, for now.
