Gridspace

Gridspace is a voice AI company (founded 2013) that now operates as Guava (goguava.ai) — a voice agent platform built for regulated industries such as healthcare, banking, insurance, BPOs, and government. Guava provides an end-to-end conversational voice stack (ASR, LLM, TTS, plus compliance guardrails) exposed through Python, TypeScript, and Elixir SDKs, a "guava" CLI, a managed cloud deployment platform, and a REST API for managing conversations, transcripts, recordings, and SMS. It supports inbound and outbound calling over WebRTC and SIP, with SOC 2 Type II, HITRUST i1, and PCI DSS posture and built-in TCPA / A2P 10DLC / SHAKEN-STIR telephony compliance workflows. The legacy gridspace.com domain now redirects to goguava.ai.

Gridspace publishes 3 APIs on the APIs.io network: Conversations API, Messages API, and SDK API. Tagged areas include Company, Voice AI, Conversational AI, Voice Agents, and Speech Recognition.

Gridspace’s developer surface includes documentation, API reference, getting-started guide, signup flow, pricing, engineering blog, support, and 31 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/gridspace: open an issue to ask a question, or submit a pull request to add artifacts. Want it done for you? Prioritized profiling — $2,500 →
