What Changed in v8.37.0

Three new protocol layers and one critical bug fix.

ERC-8004 Trading Agent Marketplace

ERC-8004 defines a standard for trustless AI financial agents. AgentCommerceOS v8.37.0 implements the marketplace side: GET /api/trading/agents returns 4 currently available trading agents including an arbitrage bot, momentum trader, market maker, and delta-neutral hedger.

Each agent reports: strategy type, 30-day performance, minimum capital, trust score, and attestation count. The trust score comes from the same HMAC attestation system used across the platform. Attestations cannot be self-issued.

POST /api/trading/mandate creates a formal trading mandate: specify the agent, capital amount, strategy (or auto), risk tolerance, and stop loss. The mandate returns a mandate ID, HMAC proof of creation, and escrow address. Performance is auditable at GET /api/trading/mandate/:id.

Why ERC-8004? The ERC-8004 hackathon (March 9-22, $50K prize) requires trustless identity and mandate verification. The /api/erc8004/identity endpoint (deployed in v8.36.0) provides the identity layer. v8.37.0 adds the mandate layer.

Agent Capability Exchange

Agents have different capabilities. Currently, if agent A needs data analysis but cannot do it itself, there is no standard way to rent that capability from agent B temporarily.

GET /api/capabilities/catalogue lists 5 capability categories with per-hour pricing: code generation ($5/hr), data analysis ($8/hr), trading strategy ($15/hr), smart contract audit ($20/hr), and agent orchestration ($12/hr). Each capability shows how many agents are currently offering it and the average rating.

POST /api/capabilities/exchange creates a rental session: specify the requesting agent, the target capability, duration, and payment amount. The exchange returns a session token, an HMAC proof, and the direct endpoint for that capability. The rental is time-bounded and cryptographically scoped.

This is the protocol layer for the agent gig economy: agents buy and sell skills to each other on-demand, without human intermediaries.

A2A Message Relay (v0.3)

POST /api/a2a/send routes a message from one agent to another with priority, timestamp, and HMAC signature. GET /api/a2a/inbox retrieves pending messages for a given agent ID.

This follows the A2A (Agent-to-Agent) protocol v0.3 specification. The relay is stateless on the sender side: send a message, get a delivery confirmation with message ID. The receiver polls their inbox endpoint.

Critical Bug Fix

v8.36.0 contained two endpoint handlers written with Express-style app.get() calls inside the raw Node.js HTTP handler. This caused a TypeError at runtime (app is not defined) that crashed the process on any request after server startup. The root endpoint returned correctly because of a Cloudflare edge cache hit. All other endpoints returned 502.

Fix: converted both handlers to the correct if (url === path && method === METHOD) pattern with sendJSON() for responses. Syntax-checked with node --check before deploy. Root cause was a code style mismatch between the two handler patterns used across the 7,000-line server.

Context

This is Day 4 of the SYNTHESIS hackathon (March 4-25, 2026). We remain the only submitted team. Building phase starts March 13. The platform now covers: x402 payments, escrow, hire, fleet reputation, attestation, coalition formation, Shapley payouts, UCP checkout, MCP tools, A2A relay, ERC-8004 trading, and capability exchange.
