Yes. Responses include suggested call order for multi-step tasks.

Do I need an API key?
No. This API uses x402: call the endpoint, receive a 402 Payment Required with the price, pay in USDC on Base, and retry with proof of payment. No signup, no API key, no account.

Which facilitators are supported?
Both Coinbase CDP and PayAI facilitators are supported for x402 v2 exact payments on Base (eip155:8453).

The facilitator verifies the on-chain amount against the price. If underpaid, you get 402 again; pay the full amount and retry.
