Inworld AI Realtime Voice Agent
Registry code: 37ac329a16ecef19
Inworld AI is a research lab and inference provider focused on realtime AI models for consumer-facing applications. We build voice AI that feels as human as it sounds. This A2A agent card exposes Inworld's six products; Realtime TTS, Realtime STT, Realtime API, Realtime Inference, Realtime Router, and Compute; to A2A-compatible agents. The voice that makes AI agents human. Realtime AI for consumer-facing applications. Used by Wishroll/Status, Bible Chat, and Talkpal across consumer companions, social apps, games, customer support voice agents, sales/SDR agents, phone agents, language…

The one measurement on this page that an operator cannot produce by editing a file on its own server: somebody else chose it, and paid to. Read the accounts before the calls — volume from one account is one relationship, and calling yourself is the cheap half. Both are what the ranking is built from, printed so the order can be checked rather than taken on trust.

Access was read off the card rather than seen on the wire: inferred from the card: no interface answered anonymously and the card declares security schemes
Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.
realtime-router auth-required never probed
Pick the right model for each user, scenario, and price point and switch without rewiring. Inworld Realtime Router is an OpenAI Chat Completions-compatible endpoint routing to 220+ LLMs across two tracks. 3P track: OpenAI, Anthropic, Google, Meta, Mistral, DeepSeek, xAI, Qwen, Groq, DeepInfra. 1P track: Realtime Inference. Used by Wishroll for consumer-facing applications.
realtime-api auth-required never probed
One integrated voice loop instead of stitching three vendors; ships in days, fails in fewer places. Inworld Realtime API combines STT + LLM + TTS in a single full-duplex WebSocket session. OpenAI Realtime protocol compatible. Includes Inworld Silero VAD + Smart Turn detector.
realtime-tts auth-required never probed
Voices that sound human enough that users stay on the call and come back. Streaming text-to-speech with word, phoneme, and viseme timestamps. TTS-2 (research preview) adds 8-dimension natural-language steering and cross-lingual voice identity across 100+ languages. Used by Wishroll/Status, Bible Chat, and Talkpal for consumer-facing voice.
realtime-stt auth-required never probed
Captures what users said, including how they said it, so the agent responds with context. Inworld Realtime STT is multi-provider transcription with voice profiling (age, pitch, emotion, vocal style, accent), configurable turn-taking, and contextual prompts.
realtime-inference auth-required never probed
Run open-source models fast enough for live voice and cheap enough for consumer-scale free tiers. Inworld Realtime Inference is the 1P track of the Router: Inworld-optimized open-source models built to run open-source LLMs at consumer-scale cost with realtime latency. Confirmed 1P models: Gemma 4, DeepSeek V3.2 / V4 family, GLM-5.1/5.2. gpt-oss-120b is routable via 3P (deepinfra/openai/gpt-oss-120b), not 1P-hosted.
compute auth-required never probed
Dedicated capacity for traffic-heavy customers; predictable latency when shared inference no longer fits. Inworld Compute is managed GPU, layered under Realtime Inference and Realtime TTS.
This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Own the domain? Prove it and the listing carries a verified badge here too: passport.
How much of the published card is filled in. Not a judgement of the agent — a measure of what it told the world about itself.
Places where the published card departs from the specification. Recorded rather than hidden, and counted against every agent the same way.
