CloudTalk

CloudTalk is an AI-powered cloud call center and business phone system (CCaaS) for sales and customer support teams, backed by Point Nine. Its public REST API (served at https://my.cloudtalk.io/api, published as OpenAPI 3.0.1 version 1.7) lets developers automate calls, contacts, agents, groups, phone numbers, campaigns, tags, SMS, blacklists and notes, and read Conversation Intelligence data — transcription, sentiment, topics, talk-listen ratio and smart notes — plus initiate VoiceAgent calls. Authentication is HTTPS-only HTTP Basic Auth using an API Access Key ID and Secret; responses are JSON, paginated with a Collections Envelope, and rate limited to 60 requests per minute per company. Events are delivered through Workflow Automation triggers (native and virtual webhooks) rather than the REST API.

CloudTalk publishes 13 APIs on the APIs.io network, including Agents API, Bulks API, Calls API, and 10 more. Tagged areas include Company, Communications, Voice, VoIP, and Call Center.

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

CloudTalk’s developer surface includes documentation, API reference, getting-started guide, support, engineering blog, pricing, signup flow, and 29 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/cloudtalk: open an issue to ask a question, or submit a pull request to add artifacts. Want it done for you? Prioritized profiling — $2,500 →
