# Generated by `pnpm generate-openapi` from the Zod contract (app/api/v2/openapi/contract/). Do not edit by hand. openapi: 3.1.0 info: title: Artificial Analysis API version: "2.0" description: | Use the Artificial Analysis dataset inside your own products, research, analysis, and monitoring systems. The API provides structured model metadata, benchmark results, pricing, and performance data across language, image, video, music, and speech. ## License and usage Use of the API requires attribution across all tiers. When you display or share API data, credit [Artificial Analysis](https://artificialanalysis.ai/) as the source. A visible byline or footer link is sufficient. Use of the API is also subject to our [Terms of Use](https://artificialanalysis.ai/docs/legal/Terms-of-Use.pdf). For redistribution rights or bespoke contract terms, [contact the team](https://artificialanalysis.ai/data-api#contact). ## Authentication All endpoints require an API key in the `x-api-key` header. ``` curl -H "x-api-key: YOUR_API_KEY" https://artificialanalysis.ai/api/v2/language/models ``` Create or copy a key from [API key management](https://artificialanalysis.ai/api-key-management-redirect). For Commercial access, [contact the team](https://artificialanalysis.ai/data-api#contact). ## Tiers | Tier | Access | Notes | | --- | --- | --- | | **Free** | The `/free` model-list endpoints — `/api/v2/language/models/free` and the 11 `/api/v2/media/.../models/free` siblings — return a Free-shape response with the public subset of fields | Standard non-`/free` routes are Pro+ and return `403` for Free API keys. Use the `/free` sibling instead | | **Pro** | Model-level access to the standard V2 endpoint set documented here, including LLM detail, pricing, richer performance data, and the Pro-shape model-list responses | This is the main paid tier for the new V2 API. Provider-level endpoints and performance over time are Commercial-only and return `403` for Pro API keys | | **Commercial** | Everything in Pro, plus provider-level language model data, performance over time (7, 30, and 90 day windows), and expanded data access negotiated on a per-organization basis. Examples include raw provider measurements, hardware data, or other ad-hoc additions | Commercial access is provisioned separately. [Contact the team](https://artificialanalysis.ai/data-api#contact) to discuss scope | ## Rate limits | Tier | Requests per day | | --- | --- | | Free | 100 | | Pro | 500 | | Commercial | Custom. [Contact the team](https://artificialanalysis.ai/data-api#contact) | ## Response headers Every authenticated response carries: - `X-AA-Tier` — the subscription tier that served the request (`free`, `pro`, or `commercial`). Mirrors the `tier` field in the response body. - `X-RateLimit-Limit`, `X-RateLimit-Remaining`, `X-RateLimit-Reset` — current rate-limit state. - `Retry-After` — included on `429` responses; seconds until the quota resets. ## Data conventions - Dates use **ISO 8601** format (for example, `2025-06-15` or `2025-06-15T14:30:00.000Z`) - Country codes use lowercased **ISO 3166-1 alpha-2** values (for example, `us`, `cn`, `gb`) - End-to-end response times assume **500 answer tokens** unless a field name states otherwise - Nulls mean "not measured" or "not applicable"; they never mean zero ## Intelligence Index versioning `artificial_analysis_intelligence_index` is a composite score, and what goes into it evolves. We version the index so you can interpret a score in context. Responses report which version produced their scores in the `intelligence_index_version` field — treat that field, not this document, as the source of truth for the current version. Full composition and version history on the [Intelligence Index methodology page](https://artificialanalysis.ai/methodology/intelligence-benchmarking). **How versions change:** - **Major version bumps** indicate a substantial change to the index definition or interpretation. Scores are best interpreted within the same major version. - **Minor version bumps** indicate methodology changes within the same major version. These may include changes to contributing evaluations, task subsets, graders, scoring/normalization, weightings, anchors, or evaluation refreshes. Scores may or may not change. **Included in v4.1** (9 evaluations): GDPval-AA v2, τ³-Banking, Terminal-Bench v2.1, SciCode, AA-LCR, AA-Omniscience, HLE, GPQA Diamond, CritPt. Older versions are documented on the methodology page. `artificial_analysis_coding_index` and `artificial_analysis_agentic_index` are derived from subsets of these evaluations and are not separately versioned. servers: - url: https://artificialanalysis.ai description: Production security: - ApiKeyAuth: [] tags: - name: Language Models description: Evaluations, pricing, performance, and metadata for language models - name: Language Model Providers description: |- Capabilities, pricing, and performance for language model API providers. **Commercial only** — these endpoints require a Commercial API key.

Excludes Pro-only fields such as the full evaluation set, token counts, blended pricing, performance percentiles, context window, parameters, modalities, licensing, and provider detail. Accepts any valid API key (Free, Pro, or Commercial).
