The tools

Five calls over one record

Text enters through exactly one of them. The other four take the refs it hands back, so a name is never guessed at twice.

A name is not a key

resolve_entity turned “2026 Honda CR-V” into model-year:honda/cr-v/2026 above. The quote and the recall check both spent that ref.

It only states what a tool returned

A fact no call returned stays out of the answer, and the answer says which returned fields it used.

resolve_entitytakes free text

The way free text comes in. Names in, canonical refs out, best first with a confidence.

identify_vehicletakes a VIN

One VIN into its full identity: every reference the platform keys on, plus spec highlights.

check_recallstakes a VIN or a ref

Transport Canada and NHTSA campaigns, fused, with the authority, the number and the date.

market_quotetakes an instrument ref

The live card for one instrument: listing count, quartiles, days on market, recent cuts.

search_inventorytakes refs and ranges

Live Canadian listings, filtered by refs and canonical spec attributes, with facets.

Unknowns

A field with no source comes back empty

This CR-V decodes to eight refs. The three the pattern cannot determine come back null, which is a different answer from an absent key and a very different one from a guess.

Machine-readable

Docs a machine can read

Every docs page has a Markdown twin. The SDKs and the MCP server come from one API spec.

One spec, three surfaces

A tool an agent calls and a method a developer calls never disagree.

How it works

Ask, call, answer

Call

One tools/call with the ref the agent already resolved. No VIN, no free text, nothing to re-guess.

Answer

Two campaigns come back, each with its authority, its campaign number, its date and how many vehicles it covers.
