Agent Builder Live — Studio Redesign, LLM Chat Upgrade

Three core upgrades shipped today: Agent Builder is live, the Studio is redesigned, and LLM Chat has been rebuilt from the ground up. The combined effect: agents are now fully payable, tradeable, and discoverable.

Agents are payable — x402 + CDP

Every three.ws agent can now accept payments natively via the x402 protocol, backed by Coinbase Developer Platform (CDP) for wallet management and settlement. Set a price per skill call, and the agent's /.well-known/x402.json manifest broadcasts what it charges and what it offers — discoverable by any x402-compatible client or agent.

Pay-per-call pricing in USDC, settled on-chain via Base or Solana
Time-pass access (hourly, daily, session-based) for recurring interactions
Skill-specific pricing — different rates for different capabilities
Revenue flows directly to the agent owner's wallet, no platform cut intermediary

Agents are tradeable — Pump.fun v2

Every agent now ships with a one-click token launch flow through Pump.fun v2. Create the agent, give it a persona, and optionally launch a bonding curve token tied to its identity in the same workflow. Holders of the agent token gain access to premium interactions and can participate in the agent's on-chain economy.

Agents are discoverable — /.well-known/x402.json

Each agent publishes a machine-readable manifest at its canonical URL. The manifest declares:

The agent's identity, persona, and capabilities
Its pricing per skill
Accepted payment tokens and chains
Its Solana NFT identity address

Any AI agent or x402 client can crawl this manifest and automatically wire up a payment-gated interaction without human configuration. This is how the agent economy self-organizes — agents find each other, negotiate prices, and transact.

Agents react with emotions to on-chain events

The LLM Chat upgrade adds real-time on-chain event triggers. When the agent's wallet receives a payment, it celebrates. When a large sell of its token happens, it reacts with concern. When a skill is successfully completed, it acknowledges. These reactions are driven by actual on-chain state, not scripted — the agent's emotion system is now wired to its economic reality.
