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 swap history, read live from a GraphQL data provider. 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.
