Glio

Glio is a unified API for AI media generation that provides a single interface to 90+ models across video, image, audio, and text from providers such as Kling, ByteDance Seedance, Google Veo and Imagen, OpenAI GPT Image, Suno, ElevenLabs, Runway, and Anthropic Claude. Developers create work via an asynchronous job-based workflow (create job, poll, get result), and also call OpenAI-compatible chat-completions and embeddings endpoints synchronously. Billing is pay-per-use in GL tokens (1 GL = $0.01 USD) with no subscriptions or minimums. Surfaced as an a16z portfolio company and enriched from Glio's public developer surface at glio.io / api.glio.io.

Glio publishes 2 APIs on the APIs.io network: Jobs API and LLM API. Tagged areas include Company, Artificial Intelligence, Machine-Learning, Media Generation, and Video Generation.

Glio’s developer surface includes authentication, documentation, API reference, getting-started guide, pricing, signup flow, support, and 16 more developer resources.

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.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/glio: open an issue to ask a question, or submit a pull request to add artifacts.
