Sperax
Render render_agent
Mount or swap the 3D avatar to a specific three.ws agent — bound to its ERC-8004 identity.
three.ws is live inside SperaxOS
Give your SperaxOS agent a body — a rigged 3D avatar that speaks, gestures, and reacts to on-chain events in real time. To launch the partnership, Sperax is handing three.ws users free AI credits on chat.sperax.io.
◆ Launch offer
Connect a three.ws agent to SperaxOS and free AI credits land on your SperaxOS account — enough to put your embodied agent to work across the Sperax DeFi stack before you spend a cent.
Claim in three steps
From zero to an embodied agent in a minute
The integration ships as a standalone SperaxOS plugin — no SDK to vendor, no bundle to submit. Install it, point it at your three.ws identity, and the credits follow.
-
Add the plugin
In SperaxOS, open Plugins → Add Plugin → Custom Plugin and paste the manifest URL:
https://three.ws/.well-known/sperax-plugin.json -
Bind your agent
Set your Agent ID — a UUID or
@handleyou copy from your three.ws dashboard. The avatar binds to that on-chain identity when the panel opens. -
Credits apply
With your agent connected, your free AI credits are active on chat.sperax.io. Start chatting — the avatar speaks, gestures, and emotes as it works.
What the avatar does
A face for DeFi, driven by the model
Your agent's LLM calls four tools. Each one drives the visible avatar in the chat panel and returns a concise result the model reads back into the conversation — so the body language always matches what's happening on-chain.
Render
Speak speak
Say a line out loud with emotional valence — greetings, narrating an action, reacting to you.
Gesture gesture
Punctuate a message with a physical gesture: wave, nod, point, or shrug.
Emote emote
Blend an emotion into the continuous Empathy Layer — concern as a position nears liquidation, celebration when a yield target hits.
Under the hood
Two halves per tool call
The host frames a hosted iframe for the visible avatar and, in parallel, POSTs the tool arguments to the three.ws gateway for the model-facing result. Both run on every call.
SperaxOS host
│ 1. LLM calls a tool (speak / gesture / emote / render_agent)
│
├─ 2a. frames /sperax/iframe/ and posts the call
│ └─▶ <agent-3d> animates the avatar in the chat panel
│
└─ 2b. gateway POSTs the arguments to the tool endpoint
└─▶ /api/chat-plugin/speak → { ok: true, spoken: "…" }
Payments
Base x402, natively
SperaxOS is EVM-native and settles agent payments via x402 over USDC on
Base (x402.sperax.io) — the same Base x402 rail three.ws
already runs. The avatar panel is chain-agnostic: it renders and animates
regardless of which chain your bound agent transacts on.
Questions
Good to know
Do I need a three.ws account?
Yes — the plugin binds to a three.ws agent, so it needs an identity to render.
Your Agent ID is a UUID or @handle you copy from
your dashboard. Don't have one?
Create an agent first, then come back.
Does the plugin cost anything or need an API key?
No. The only setting is your public Agent ID — there's no API key to paste. The free credits cover your usage on SperaxOS while the launch offer runs.
Which chain does this settle on?
SperaxOS settles agent payments via x402 over USDC on Base, matching three.ws's Base x402 rail. The avatar itself renders regardless of chain — see Base x402, natively above.
Where's the technical detail?
The full plugin reference — manifest, tools, and local testing — lives in the manifest and the integration write-up at three.ws Ships Inside SperaxUSD.
