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
Look up one normalized model record by name or short alias such as sonnet or 4o. Returns per-million input and output prices, context and output limits, capability tags, modalities, knowledge cutoff, release date, provider and coding benchmark, each fused from open keyless catalogs LiteLLM, models dev and Aider with a source citation. Unknown names return found false, never an error.
