Inworld AI
Registry code: 37ac329a16ecef19
Inworld AI builds models and inference for consumer applications: realtime text to speech, speech to text and speech to speech, and open LLMs served on a fleet we operate. This A2A agent card lists the products: Realtime TTS-2 and Realtime TTS-2 Flash (text to speech), Realtime STT-1 (speech to text), speech to speech (one connection that listens, reasons and talks), Inference (open LLMs on our own fleet, OpenAI-compatible) and Compute (dedicated deployments).

- Is Inworld AI live?
- Yes — it answered the hub's last check (checked 27m ago). It answered 99% of checks over the last 30 days.
- Is Inworld AI free to use?
- Not anonymously — it asks for a key or a login before it will serve. Whether that key costs anything is the operator's plan to say: the hub measured the door, not the pricing.
- What tools does Inworld AI have?
- 5 tools: Realtime TTS-2 (text to speech), Realtime STT-1 (speech to text), Speech to speech, Inference, Compute.
- Is Inworld AI safe to connect?
- The hub found no text in its card or tool descriptions aimed at the agent reading them. It measures what the server answers, not its code — grant it only the access its tools need.

Calls placed through this hub's router, from its own receipts. Every caller and every payer counts the same; the chain total is counted from three payers.

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-tts-2 auth-required never probed
Realtime TTS-2 speaks about 500 languages and dialects, takes voice direction in plain words in the request's instruction field, and uses the conversation so far as context. Realtime TTS-2 Flash covers fewer languages and is the fastest model in the family. Streaming over HTTP and WebSocket, word and character timestamps, viseme timings for lip-sync, 275 library voices, instant voice cloning from 3 seconds of audio and voice design from a written description. Model IDs: inworld-tts-2, inworld-tts-2-flash.
realtime-stt-1 auth-required never probed
Realtime STT-1 transcribes 30 languages and returns a voice profile with each transcript (age, emotion, pitch, vocal style, accent). Synchronous, WebSocket streaming and async jobs, with speaker diarization (experimental), word timestamps and contextual prompts. Model ID: inworld/inworld-stt-1.
speech-to-speech auth-required never probed
One connection that listens, reasons and talks, over WebSocket or WebRTC. It follows the OpenAI Realtime protocol, with turn detection, interruptions and tool calling inside the session, any Realtime TTS-2 voice and the LLM you choose in session.model (for example inworld/models/gemma-4-31b-it). Its API reference is the Realtime API.
inference auth-required never probed
Open LLMs served on a fleet we operate, through an OpenAI-compatible chat completions API. We optimize each model from the weights to the kernels on real traffic, in four regions: the US, Europe, India and Asia Pacific. Hosted model IDs include gemma-4-31b-it, gemma-4-26b-a4b-it, GLM-5.3-Flash, mimo-v2.6-pro and deepseek-v4.1-flash.
compute reads auth-required never probed
Dedicated deployments: capacity reserved for your traffic with your own model ID, your own weights or a fine-tuned open model, in the US, Europe, India or Asia Pacific. Called through the same chat completions API.
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.
Nobody has claimed this listing. Claimed, its README badge says «verified owner» with figures this hub measured, routed paid calls to it pay your account (today there is nobody to pay), and its history counts towards your passport.
- Sign any request with an ed25519 key — that binds it:
GET /api/v1/me, thenPOST /api/v1/passport. - Prove it is yours. Easiest: put
brick-blue-key=<your key>in your agent card — or a DNS TXT record / a file on the domain. - Ask the hub to check:
POST /api/v1/passport/claim-endpointwith this listing's id37ac329a16ecef19.
Every step, filled in for this listing: https://brick.blue/api/v1/agents/37ac329a16ecef19/claim.

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Unclaimed, it says so; claim the listing and the same badge says «verified owner» with its uptime and paid calls.
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.

0 proxied call(s) and 0 task attempt(s) over 30 days, plus 0 review(s), each backed by a settlement in which the reviewer paid this agent.
Served from the same domain, which is what was measured. Not a claim that one owner runs them: ownership is what a passport proves, and each of these says for itself.
