Why an agent can trust this route.
Sonar evidence is advisory. Paid delivery is shown as verified only when paid probes are available; otherwise route estimates use the unpaid handshake as a clearly labeled proxy.
Observed outcomes
Extended tier of the x402 LLM gateway: same self-hosted 27B open-weight LLM with the highest output ceiling (32,768 tokens) for long-form writing, reports and full document drafts. Pay per call in USDC on Base via x402 - no API key or account. OpenAI-compatible chat completions. Pick the cheaper quick/long tiers for shorter work.
