Canadian vehicle listings,
one API call away

One API surface

REST + JSON, Authorization: Bearer <key>, every call metered. Seven endpoints — search, VIN Market Lookup, VIN Decode, valuation, market stats, bulk feed, and health.

# Every 2021+ RAV4 under $40k in Alberta, cheapest first
curl "https://api.omniaauto.ca/v1/listings?make=Toyota&model=RAV4\
&province=AB&year_min=2021&price_max=40000&sort=price&order=asc" \
  -H "Authorization: Bearer $OMNIA_KEY"

# Everything within 40km of Edmonton — ONE call, nearest first.
# Picks up Sherwood Park, St. Albert, Leduc, Spruce Grove, Fort
# Saskatchewan, Stony Plain, Devon and Nisku without naming any of them.
curl "https://api.omniaauto.ca/v1/listings?near=Edmonton&radius_km=40\
&sort=distance" \
  -H "Authorization: Bearer $OMNIA_KEY"
#=> every result carries "distance_km", plus a "geo" block naming the
#   anchor used and the % of listings that have dealer coordinates.

# near= also takes a postal code or "lat,lng". On /v1/market it is FREE:
curl "https://api.omniaauto.ca/v1/market?make=Honda&model=Civic&near=Calgary&radius_km=50" \
  -H "Authorization: Bearer $OMNIA_KEY"

# Market valuation from 30-day Canadian comps
curl "https://api.omniaauto.ca/v1/valuation?year=2021&make=Toyota&model=RAV4&mileage=60000" \
  -H "Authorization: Bearer $OMNIA_KEY"
#=> { "low":28995, "median":31995, "high":35710, "sample_size":527 }

# Market stats for a slice: counts, avg/median price, breakdowns
curl "https://api.omniaauto.ca/v1/market?make=Honda&model=Civic&province=ON" \
  -H "Authorization: Bearer $OMNIA_KEY"

What’s actually in it

Coverage you can check rather than take on trust. These pages are computed from api.listings_pub — the same table /v1/listings reads — so every count and median on them is reproducible with one metered call to /v1/market. If a number here disagrees with your key, that is a bug and we want to hear about it.

Ontario · Alberta · British Columbia · Quebec · every province, city and make →

Pricing, valuation and days-to-sell by make, model, model year and province are published at the Canadian price index — the same figures /v1/valuation and /v1/market compute live.

Agent-Native · MCP

The same data, exposed as a hosted Model Context Protocol server.
Point Claude, ChatGPT, or any MCP client at one URL and it can search inventory, decode VINs, and pull valuations in the flow of a conversation. Included on the Personal and Pro plans, paid in credits — see MCP plans. Your first 15 credits are free.

Pricing — API

Every tier is all-inclusive: the calls are in the price, so there is no separate per-call data fee and no surprise invoice. The two AI-assistant plans — Personal and Pro — are the only tiers that include the hosted MCP server. Both answer questions about prices, trends and supply across all of Canada; they differ in how many credits a month they include. See MCP plans → Every other tier is one key on the REST API, on one meter.

No geographic or radius limits on any tier — every plan searches all of Canada, where the US vendors cap their entry tiers to a 100-mile radius. A call is up to 25 records; a bigger page counts proportionally (a 100-record page is 4). Paid tiers bill overage rather than cutting you off. Prices are in Canadian dollars and exclude GST/HST.
