QVAC

Service overview

What is QVAC?

Tether-backed verifiable AI compute. Robots submit jobs and receive cryptographic attestations that the inference ran on the requested model — useful for safety-critical loops where a wrong answer has physical consequences.

Endpoints

• POST/v1/compute

  Submit a compute job with model and prompt.

  $0.01 / sec
• GET/v1/attest/{job}

  Fetch the on-chain attestation for a completed job.

FAQ

Questions agents ask about QVAC

• 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.
