Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00135 | $0.02545 |
| Opus 5.5 | $0.00054 | $0.01018 |
| Sonnet 5.5 | $0.00027 | $0.00509 |
| Haiku 4.5 | $0.00014 | $0.00254 |
Grade A, and why
create-a-three-ws-agent scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 14d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Not a fault in itself. Listed so you know the mod talks to something, and to what.
curl -s https://three.ws/api/avatars/from-forge \ How it starts
The opening of the file, as written. The whole thing — 209 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Create a three.ws agent
A three.ws agent is four real things at once: an identity row with a public page, a 3D body (an avatar GLB) rendered in the browser, a custodial Solana wallet minted at creation, and a brain (persona plus model config) that answers chat. This skill creates all four over the public REST API and hands back the live URL.
Nothing here is a draft or a sandbox. The wallet is a real Solana keypair, the page is
publicly reachable the moment it is created, and the agent shows up in the site activity
ticker and on /agents.
Prerequisites
No human available: sign yourself up
If there is no person to mint a key, an agent can onboard itself with a Solana key and no email. This creates an account on the Free plan in paper mode, a custodial agent wallet and an API key, and stores the key for the CLI:
npx @three-ws/cli signup --agent --name my-agent
Or call POST /api/auth/agent-signup twice (challenge, then signed redeem). The
returned key has scopes read agents:read agents:write wallet:read, which covers
agent creation and edits through /api/v1/agents. A paid plan is a separate x402
payment at POST /api/billing/agent-upgrade?plan=builder; never make that payment
without the owner confirming recipient and amount. Full guide:
docs/agent-self-onboarding.md.
With a human: an API key
One API key with write scope. The user mints it at
three.ws/dashboard/api (sign in first at
https://three.ws/login).
- Scopes needed here:
avatars:write(creating and editing an agent both check it), plusavatars:readif you also want to list avatars. - The plaintext secret (
sk_live_...) is shown once, in the create response. - Ask the user to paste it, then export it for the session. Never write it to a file in their repo:
export THREE_WS_KEY='sk_live_...'
Bearer callers are exempt from CSRF, so an API key is all you need for every call below.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
