List models

GET/models

Lists the catalogue as JSON, with no key needed: chat, embedding and image models, each entry's kind saying which. The catalogue answers even with a mistyped key, so a 200 here does not prove your key works — a chat call does (where each model runs).

Query parameters

kindstring
One family only. Without it, the list holds all three.
Valueschatembeddingimage

Fields of an entry

application/json

idstring
The model ID: the value of model in your calls.
objectstring
model, as in OpenAI's format.
kindstring
The model's family.
Valueschatembeddingimage
createdinteger
Unix time, as in OpenAI's format.
owned_bystring
The model's maker.
operatorstring
Who runs the model — the value of the x-evanesca-operator header.
Valuesmistralakiscalewayovhcloudinfomaniak
locationstring
Where it runs — the value of the x-evanesca-location header.
Valuesparisgravelinesmistral-eu-regiongermanyswitzerland
context_lengthinteger
The context window as the operator announces it; absent while it has not been checked.
tool_callingboolean
true or false where tool calling was measured with a real call; absent where it was not.
reasoningboolean
Whether the model thinks before it answers.
pricingobject
currency, vat_included, input_per_million and output_per_million: euros per million tokens, VAT included.
licence, open_weightsstring | null · boolean
The licence as published — null while none is — and whether the weights are public.
checksobject
The six checks as booleans — licence, provenance, security, gdpr, benchmarks, live_test — and, in run_on, the date of each passed check where it is known. false means missing: not run yet, or run without meeting the pass mark.
retentionobject
What the operator says it keeps (rule), and the page where it says so (source). Evanesca itself stores no prompt.
trainingobject
What the operator says about training on your data (statement), and its source (source).

Where it runs, what it costs

Evanesca · on the record

Answered by: Evanesca's catalogue: no model runs, no operator is called.

Costs: Nothing: no key, no credit.
