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
Cheapest-model query: returns the lowest-cost AI models matching your constraints — min_context (tokens), vision/function_calling/reasoning (true), max_input_per_mtok (USD cap), limit (default 5). Add expected_input/expected_output token counts to rank by blended USD per request instead of input price; exclude_preview=true skips pre-release models. Answers 'what is the cheapest model that can do X?' across 2,000+ models and 70+ providers.
