Gradient Labs

Gradient Labs builds "Otto", an AI customer support agent that autonomously handles complex, end-to-end support conversations for regulated and financial services businesses. The API lets you start and drive conversations, stream customer messages, hand off to human agents, execute business actions/tools, and manage the knowledge base the agent reasons over, with signed webhooks delivering the agent's outbound messages and events.

Gradient Labs publishes 6 APIs on the APIs.io network, including Actions & Tools API, Conversations API, Hand-off API, and 3 more. Tagged areas include Artificial Intelligence, Customer-Support, AI Agent, Conversations, and Financial-Services.

Gradient Labs’ developer surface includes authentication, documentation, engineering blog, and 8 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/gradient-labs: open an issue to ask a question, or submit a pull request to add artifacts.
