ActiveFence

ActiveFence — now operating as Alice — is an AI security, safety and trust & safety company headquartered in New York and Tel Aviv. It sells two product families through one REST API at api.alice.io: ActiveFamily (ActiveScore automated detection plus the ActiveOS moderation workbench) for user-generated-content trust and safety across text, image, video and audio in 120+ languages and 20+ abuse areas; and WonderSuite for generative-AI protection — WonderBuild (pre-deployment red teaming and adversarial assessment of models, apps and agents), WonderFence (real-time runtime guardrails that evaluate prompts and responses for prompt injection, jailbreaks, PII leakage and policy violations) and WonderCheck (ongoing post-launch evaluation and drift detection). The API offers synchronous endpoints for low-latency moderation and asynchronous endpoints that acknowledge receipt and post results back to a customer-configured callback URL, plus configurable action webhooks fired from the ActiveOS moderation view or an automated workflow. Authentication is a single af-api-key header issued from the platform console; the default rate limit is 50 requests per second. First-party SDKs ship for Python (wonderfence-sdk) and TypeScript (@alice-io/wonderfence-ts-sdk), with a Parlant integration and the open-source Caterpillar agent-skill security scanner. Alice is SOC 2 and ISO 27001 certified.

ActiveFence publishes 7 APIs on the APIs.io network, including api keys API, Collection API, Content API, and 4 more. Tagged areas include AI Safety, AI Security, Trust and Safety, Content Moderation, and Guardrails.

The ActiveFence catalog on APIs.io includes 1 event-driven AsyncAPI specification.

ActiveFence’s developer surface includes documentation, API reference, getting-started guide, support, engineering blog, CLI, authentication, and 23 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/activefence: open an issue to ask a question, or submit a pull request to add artifacts.
