A vehicle listings APIwith no extra listings plan sitting on top of it
Marketcheck is an established automotive data platform, and it publishes its API rates: plan tiers with a per-call data fee for each endpoint, and a free tier to start on. Hermes Data does not sell a separate listings subscription. Start the $0.99 Hermes trial or any self-serve plan, generate a key, and every call draws its own millicredits from a wallet shared with the rest of the platform - 21,306,373 live listings and 7,265,753 unique VINs as of October 13, 2026, one key for the United States and Canada.
Do I need a separate listings subscription?
Hermes Data is a vehicle listings API with no extra listings SKU. Marketcheck is the broader platform by some distance - cars, recreational vehicles, motorcycles and heavy equipment across North America and the United Kingdom - and it publishes plan tiers with a per-call fee for each endpoint, which is more openness than most data vendors offer. The difference here is commercial shape and what gets measured. You still need a Hermes trial or plan. Billing is then per API call in millicredits: 1 for a keyed lookup, 2 for an aggregate, 5 for a full record and 10 for a scan, which works out to roughly 10,000 listings per credit when you page search results at 100 per call. Failed requests are never billed, there is no separate listings monthly floor, and the same balance pays for Contacts, Dealers and Dealer Groups. Coverage is stated exactly and dated: 21,306,373 live listings across 71,791 dealer websites on October 13, 2026, with field fill rates published including the ones below 100%.

Where Marketcheck goes further
Vehicle history behind a VIN, enhanced and build-level VIN decoding, price prediction, United Kingdom coverage, and recreational vehicles, motorcycles and heavy equipment. Hermes Data sells none of that. If your product needs listing history or a valuation model, we are not the vendor - and their crawl is larger than ours by their own published figures.
No extra listings tier on top of Hermes
Marketcheck publishes its rates and so do we, which is rarer in this market than it should be. The difference is that Listings is not a separate product plan. Start a Hermes trial or subscribe, then every call is metered in millicredits from the same wallet as Contacts, Dealers and Dealer Groups. Unused credits roll over, and the live cost table is readable from the API itself, so your code can price a call before it makes it.
Coverage with a date on it
As of October 13, 2026 we were carrying 21,306,373 live listings and 7,265,753 unique VINs, scanned from 71,791 dealer websites. Those are exact counts read from production, not rounded marketing floors, and the page they appear on refreshes them.
Fill rates in the open
91.8% of listings carry a VIN and 96.3% carry at least one photo. We publish the weaker fields too, because a quality table with the inconvenient row removed is worse than no table - it still looks like disclosure while hiding the thing you would have asked about.
Frequently asked questions
Do I need a separate listings subscription?
No extra listings plan. Start the $0.99 Hermes trial or any self-serve plan, generate a bearer key, and each call spends its own millicredits - 1 for a keyed lookup, 2 for an aggregate, 5 for a full vehicle record and 10 for a scan, with 1,000 millicredits to a credit. Paging search results at 100 listings per call comes to about 10,000 listings per credit. Walkthrough credits sit in the wallet until a trial or plan is active. Errors are not billed.
How does Hermes Data compare with Marketcheck on coverage?
Marketcheck is wider. It crawls a larger set of sites, covers the United Kingdom, and carries recreational vehicles, motorcycles and heavy equipment alongside cars. Hermes Data covers cars in the United States and Canada only. What we publish in exchange is precision: an exact, dated listing and VIN count, the number of dealer sites behind it, and the fill rate for each field, so you can check the fit before you write a line of code.
How many vehicle listings does Hermes Data cover?
As of October 13, 2026, 21,306,373 live retail listings across the United States and Canada, covering 7,265,753 unique VINs scanned from 71,791 dealer websites. The counts are published at full precision and dated, so they can be checked rather than taken on trust.
What can the listings API actually do?
It is a read-only query API. You can search and page inventory, look a vehicle up by ID or VIN, pull a full record with options, features, photos and seller details, list a dealer's inventory, fetch comparables, and read regional, year-make-model or market-days-supply statistics. There is no bulk file download on the query API - it is built for live queries against current inventory.
