How this service works
The checks your agent runs before it acts: verify a bank account, a phone number, a law in force, the weather or a vehicle — computed from official sources, with provenance in every response. You only pay for answers.
Output
Returns the official EU CO2 emissions figure for the specified vehicle (by make, model, and year or type-approval number), along with provenance metadata indicating the source data from the EU registry. A 404 is returned if the year is outside the ingested window, with a message naming the valid years available.
Example use cases
Pre-purchase emissions verification
“Before I buy this used 2019 Volkswagen Golf, can you check what the official EU CO2 emissions figure is so I can confirm the seller's claim is accurate?”
Fleet compliance CO2 reporting
“I need the official EU CO2 figure for a 2021 Peugeot 208 for our fleet emissions report — can you get that with the source provenance included?”
Car comparison for eco-conscious buyer
“Can you look up the official EU CO2 emissions for a 2022 Toyota Yaris and a 2022 Renault Clio so I can compare which one is greener?”
Technical details
Endpoint
GEThttps://api.invoket.com/vehicle/co2When to prefer
Use this endpoint when you need authoritative, provenance-backed CO2 emissions data sourced from the EU type-approval registry — especially for pre-purchase vehicle checks, fleet compliance reporting, or verifying dealer-provided emissions claims. Prefer this over general web searches when you need official data with a traceable source rather than estimated or aggregated figures.
Side effects
- 400 error if both the approximate key (make+model+year) and precise key (type_approval) are mixed in the same request
- 404 error if the requested registration year is outside the ingested EU data window — response includes valid year range
- Make or model not found if spelling is too ambiguous and cannot be folded to a known entry
- Missing required fields (make, model, or year all required together) returns a 400 validation error
Input
Schema · Request body
| Field | Type | Description |
|---|---|---|
| makerequired | string | Make of the vehicle (e.g. 'Renault'); short forms and member-state spellings are folded ('VW' and 'VOLKSWAGEN VW' both reach VOLKSWAGEN). Use either this approximate key — make, model and year, all three required together — or the precise one: 'type_approval' (the EU type-approval number, optionally narrowed by 'variant' and 'version'). Mixing the two keys is a 400 |
| yearrequired | string | Registration year (YYYY) within the ingested window; a year outside it is a 404 whose message names the years actually served, never a silent miss |
| modelrequired | string | Commercial name as reported to the EU registry (e.g. 'Clio'); case and accents are folded. Required together with 'make' and 'year' |
