Syllable

Syllable is a Mountain View, California company (founded 2017) that operates an agentic platform for building, deploying and optimizing AI voice, SMS, email, web-chat and WhatsApp agents, with a strong focus on healthcare patient experience and contact-center automation. The Syllable Platform SDK exposes a REST API at api.syllable.cloud covering agents, prompts, tools, services, data sources, channels and channel targets, sessions and transcripts, outbound campaigns and batches, insights workflows, directory, dashboards, incidents, organizations, roles, permissions and users. First-party TypeScript and Python SDKs, a Go CLI, a documentation MCP server and a published A2A agent card make it an unusually agent-forward developer surface.

Syllable publishes 41 APIs on the APIs.io network, including Agents API, Agents.test API, Bridge Phrases API, and 38 more. Tagged areas include Company, Artificial Intelligence, AI Agents, Voice, and Conversational AI.

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

Syllable’s developer surface includes documentation, API reference, getting-started guide, support, engineering blog, pricing, signup flow, and 32 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Telecommunications 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.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. This rating is computed from github.com/api-evangelist/syllable: open an issue to ask a question, or submit a pull request to add artifacts. Want it done for you? Prioritized profiling — $2,500 →
