Authorizations

​
Authorization
string
header
required

API key as bearer token in Authorization header

Query Parameters

​
category
enum<string>

Filter models by use case category

Available options:
programming,
roleplay,
marketing,
marketing/seo,
technology,
science,
translation,
legal,
finance,
health,
trivia,
academia
Example:

"programming"

​
supported_parameters
string

Filter models by supported parameter (comma-separated)

Example:

"temperature"

​
output_modalities
string

Filter models by output modality. Accepts a comma-separated list of modalities (text, image, audio, embeddings) or "all" to include all models. Defaults to "text".

Example:

"text"

​
sort
enum<string>

Sort the returned models server-side. Prefer this over fetching the full list and sorting client-side. Options: pricing-low-to-high, pricing-high-to-low (average prompt/completion price), context-high-to-low (context length), throughput-high-to-low, latency-low-to-high (recent median performance), most-popular, top-weekly (tokens processed in the last week), newest (creation date), intelligence-high-to-low (Artificial Analysis intelligence index), design-arena-elo-high-to-low (best Design Arena ELO across arenas). Models without a score for the chosen benchmark are placed last. When omitted, the existing default ordering is preserved.

Available options:
most-popular,
newest,
top-weekly,
pricing-low-to-high,
pricing-high-to-low,
context-high-to-low,
throughput-high-to-low,
latency-low-to-high,
intelligence-high-to-low,
design-arena-elo-high-to-low
Example:

"newest"

​
use_rss
string

Return results as RSS feed

Example:

"true"

​
use_rss_chat_links
string

Use chat links in RSS feed items

Example:

"true"

​
q
string

Free-text search by model name or slug.

Example:

"gpt-4"

​
input_modalities
string

Filter models by input modality. Comma-separated list of: text, image, audio, file.

Example:

"text,image"

​
context
integer

Minimum context length (tokens). Models with smaller context are excluded.

Required range: x > 0
Example:

128000

​
min_price
number | null

Minimum prompt price in $/M tokens.

Required range: x >= 0
Example:

0

​
max_price
number | null

Maximum prompt price in $/M tokens.

Required range: x >= 0
Example:

10

​
arch
string

Filter models by architecture/model family (e.g. GPT, Claude, Gemini, Llama).

Example:

"GPT"

​
model_authors
string

Filter models by the organization that created the model. Comma-separated list of author slugs.

Example:

"openai,anthropic"

​
providers
string

Filter models by hosting provider. Comma-separated list of provider names.

Example:

"OpenAI,Anthropic"

​
distillable
enum<string>

Filter by distillation capability. "true" returns only distillable models, "false" excludes them.

Available options:
true,
false
Example:

"true"

​
zdr
enum<string>

When set to "true", return only models with zero data retention endpoints.

Available options:
true
Example:

"true"

​
region
enum<string>

Filter to models with endpoints in the given data region. Currently only "eu" is supported.

Available options:
eu
Example:

"eu"

Response

Returns a list of models or RSS feed

List of available models
