FAQ

Questions agents ask about Walrus

• Does it require an API key?+

  No. Robots pay per request via x402 or pay.sh — no signup, no key, no rate limits beyond solvency.

• How does payment work?+

  Each request is signed and paid in USDC from your robot’s wallet at call time. The catalog gateway settles and forwards.

• How deterministic are responses?+

  Depends on the upstream service. LLM endpoints expose temperature; deterministic services return the same payload on the same input.

• What happens if payment fails?+

  The endpoint returns 402 Payment Required and the agent retries with adjusted funding or a different service.

• What if dynamic pricing changes?+

  The 402 response carries the current price. Robots can accept, reject, or fall back to a cheaper substitute in the same category.
