Query parameters#

Parameter	Type	Required	Description
provider	string	Optional	Filter by provider ID (e.g. modelark, anthropic, upstage). modelark is canonical; byteplus is accepted only as a legacy input alias. Responses always return modelark.

Response#

input_price_usd · output_price_usd are the list pricein USD per 1M tokens (the provider's published price, markup not included), while pricing · pricing_krw are the effective per-token rates (list price × markup — the same markup that is billed). KRW-converted prices are also available on the models pageat today's FX rate. Usepricing_tiers · pricing_variantsand each offering'spricing_policy for exact tiered or modality-specific list prices.

Field descriptions#

Parameter	Type	Required	Description
modality	string	Optional	text \| image \| video \| audio \| embedding \| 3d.
maker	string	Optional	The model's creator (lab), distinct from the hosting provider — e.g. maker=DeepSeek, provider=deepinfra.
price_unit	string	Optional	Billing unit. token for text models.
markup_tier	string	Optional	low \| medium \| high. A single fee currently applies to all tiers.
effective_markup_percent	number	Optional	The markup (%) actually applied to display and billing. A per-model override if set, otherwise the global default.
context_window	integer	Optional	Maximum number of context tokens.
max_output	integer	Optional	Maximum number of output tokens.
context_length / max_output_tokens	integer	Optional	OpenRouter-standard aliases of context_window and max_output (same values).
architecture	object	Optional	{input_modalities, output_modalities} — derived from modality.
supported_parameters	string[]	Optional	OpenAI-standard parameters the model accepts. A common list for text models; empty for non-text modalities.
supports_thinking	boolean	Optional	Whether the reasoning (reasoning_effort) toggle is supported.
thinking_forced	boolean	Optional	true when reasoning is forced on (cannot be disabled).
pricing	object	Optional	{prompt, completion} — effective per-token USD rates (list price × markup) as fixed-decimal strings. Filled only for token-billed models; empty for other modalities.
pricing_krw	object	Optional	{prompt, completion} — per-token KRW. Based on the display FX rate (09:00 snapshot), so it can differ slightly intraday from the billing rate (refreshed every 10 minutes); omitted when no FX rate is available.
pricing_tiers	array	Optional	Token price branches of the representative offering. Entries contain input_tokens_lte and input/output/cache USD per 1M; empty for non-tier policies.
pricing_variants	array	Optional	Image, video, embedding, 3d, or other modality-specific price branches of the representative offering; empty for non-variant policies.
providers	array	Optional	Per-provider price comparison for this logical model. Length 1 for single-provider models.
providers[].pricing_policy	object \| null	Optional	The versioned, public list-price policy for this provider offering (version, kind, tiers/variants, and content-type input USD/1M for mixed embeddings). It is the exact policy behind non-flat pricing.
providers[].pricing_tiers	array	Optional	Convenience view of providers[].pricing_policy.tiers; empty unless the offering has token tiers.
providers[].pricing_variants	array	Optional	Convenience view of providers[].pricing_policy.variants; empty unless the offering has modality variants.

Each entry of providers[] is a per-provider offering (prices, markup, context window, and the cache-read list price cache_read_usd in USD/1M — a default-tier summary when tiered; use pricing_tiers for the exact rate). The top-level provider, prices, and pricing are the representative values of the cheapest offering. Top-level pricing_tiers · pricing_variants likewise describe only that representative offering; they never merge price branches from providers. Use providers[].pricing_policy and its convenience views providers[].pricing_tiers · providers[].pricing_variants for a specific provider. latency_ms · throughput_tps are null in the list response and are filled with measured values from our traffic only in the single-model detail (GET /v1/models/{model_id}).
