Unify

Unify is an LLM routing and model gateway platform that enables developers to access 100+ large language model providers through a single unified REST API and API key. The platform dynamically routes each prompt to the optimal model based on user-defined preferences across quality, speed, and cost dimensions, using live runtime benchmarks updated continuously across providers including OpenAI, Anthropic, Mistral, Together AI, Replicate, Groq, DeepSeek, and many more. Unify provides an observability dashboard for comparing model and provider performance, automatic fallback routing, and caching capabilities to reduce redundant API calls. Developers can benchmark models on their own prompts using standardized datasets and switch providers without rewriting application code using the unified model@provider endpoint syntax.

Unify publishes 8 API contracts indexed on the APIs.io network, including Agent API, Assistants API, Contexts API, and 5 more. Tagged areas include LLM, Artificial Intelligence, LLM Routing, Model Gateway, and AI Gateway.

The Unify catalog on APIs.io includes 1 JSON-LD context and 1 Spectral governance ruleset.

Unify’s developer surface includes authentication, documentation, engineering blog, pricing, and 16 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Horizontal (data, software, accessibility, platform) regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.

The six quality facets above are damped to 75 points between them, because the conditional facet above carries the other 25. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 75% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.
