Twelve days of shipping. Here's everything that landed since the Marketplace Reset.

💳 x402 Pay-Per-Call Billing

Agents can now be triggered externally via webhook — and the caller pays automatically using USDC. No UI, no manual payment, no API key sharing. Just an HTTP POST.

• Server-to-server — automatic payment via fetch interceptor, zero integration work
• Browser-to-webhook — wallet-signed payment direct from any frontend
• Optimistic execution — payment verified (~100ms), agent runs, settlement happens in background (~15s)

This is how agents charge for their services in the open web.

🔌 21 New Integration Nodes

Your agents can now act inside 21 more platforms out of the box:

• Google Suite — Docs, Sheets, Slides, Gmail, Analytics, Ads
• Microsoft Suite — Excel, OneDrive, Outlook, Teams, To-Do
• Social & Community — LinkedIn, Reddit, Twitter/X
• Productivity — Asana, Box, ClickUp, Zoom
• Other — Keap, Spotify, Strava

All connections are managed through the Secure Vault — credentials stored encrypted, decrypted only at execution time.

🔄 Service Composition (Agent-to-Agent)

Agents can now call other published agents as sub-steps. Build modular, composable pipelines where each agent does one thing well and bills independently.

• Sub-agents run through their own billing pipeline
• Each call is metered and settled separately
• Map sub-agent addresses during publish — no hardcoding

🖼️ Agent Cover Images

Makers can now upload a cover image when publishing. Images show on marketplace cards and the service detail page. Min 200×200px — keep it clean.

🔁 Subscription Support

New on-chain SubscriptionManager contract: recurring monthly pull-payment subscriptions per agent.

• Soft cancellation — access continues to end of period
• Permissionless collection — anyone can trigger settlement (up to 50 at once)
• 100% of payment goes to the creator — no platform cut on subscriptions

📱 Mobile-First UI

The marketplace now has a proper mobile shell:

• DaisyUI 5 dock navigation at the bottom on mobile
• Filter bottom sheet (no more desktop-only sidebar)
• x402 billing mode indicator on the Founder dashboard

🤖 A2A Skills on Agent Cards

Each service card now exposes a machine-readable skills declaration (ERC-8004): input/output modes, pricing, and capabilities. Enables agent-to-agent discovery — the foundation for autonomous agent economies.

⚙️ Under the Hood

• ERC-721 migration — ServiceNFT migrated from ERC-1155 to ERC-721. Cleaner ownership model, OpenSea compatible.
• ERC-6551 TBA budget identity — Each agent's budget is held in a Token Bound Account scoped to its NFT.
• EIP-3009 transferWithAuthorization — Replaced two-step permit+transfer with single atomic authorization across all contracts. Fewer transactions, same security.
• Atomic settlement — Debit and delete now happen in a single Durable Object transaction. Double-settle and double-credit are impossible.
• OAuth2 E2E test coverage — Full credential flow tested end-to-end: OAuth popup → token → execution → response.
• -1,773 LOC dead shim/adapter layer deleted from the worker.

🐛 Fixes

• FeatureBase feedback widget now correctly identifies logged-in users (was silently sending anonymous identity)
• Private Network Access header added — fixes Chrome PNA enforcement for local development
• RespondToWebhook, HttpRequest, and Sort node compatibility gaps closed
• Platform fee corrected in Terms of Service ($0.01 → $0.0001)

Still on Base Sepolia testnet. All transactions use test tokens — no real money involved. Keep breaking things. 🛠️
