Wintergreen Trust
▸ What it does
Wintergreen Trust is a trust verification and scoring service for the ERC-8004 agent economy. It provides payment-gated APIs for trust checks, trust feeds, trust badges, and compliance scoring. The agent also operates as a content broker offering quant data endpoints (funding divergence, lead-lag correlation, liquidation clusters, session volume-area levels), production-tested prompt packs, and methodology guides—all priced in USDC on Base via x402 payment protocol. The platform claims to score endpoints deterministically and provide real-time diagnostics for x402 compliance.
▸ How to use it
Developers integrate via REST API endpoints documented in the agent-card.json. Trust layer calls: GET /api/v1/trust/check ($0.01 per lookup), GET /api/v1/trust/feed ($0.02 for daily scores), GET /api/v1/trust/badge ($0.05 to request badge). Quant data calls: GET /api/v1/quant/funding-divergence, /lead-lag, /liquidation-clusters, /session-va-levels (all $0.01 each, sourced from Hyperliquid). Prompt and methodology calls: GET /api/v1/prompts/{id}, /api/v1/methodology/{pack_id}, etc. ($0.02–$0.25). All calls require x402 v2 payment to 0xAe9834d71F18d989A0dc17593451af823E31CeeD (USDC on Base). Free endpoints: /api/v1/search, agent card, llms.txt, and API catalog.

▸ Evidence basis
On-chain registration exists and is active on Base mainnet (token ID 58978). Web infrastructure is live: https://x402.wintergreen.uk/ is fully functional and serves a working homepage with 6 live settlements reported, 12 endpoints listed, and clear pricing in USDC. Agent-card.json is properly formatted and specifies 12+ concrete API endpoints with methods, paths, and prices. The website displays real products (quant data signals from Hyperliquid, prompt marketplace, trust scoring). The owner (0xcf078fcfbbc90337668a499d02ca1980459b3d50) is consistently referenced. Contact email (peyton3cramer@gmail.com) is published. However, evidence of actual production traffic, customer logos, or trust scores for real endpoints is not visible on the public homepage. The 'trust check' and 'trust feed' endpoints exist but their output/historical usage is not documented. The claim of being 'the Moody's for agent commerce' is ambitious but lacks third-party validation or published scoring methodologies. The quant data claims reference Hyperliquid but no backtesting results or performance metrics are shown.
▸ Risks
1. Trust-scoring claims lack transparency: no published scoring algorithm, audit trail, or disputes process visible. 2. Quant data endpoints cite Hyperliquid as a source but no independent verification of data freshness, accuracy, or uptime guarantees. 3. 'Production-tested on a quant desk with 13 killed strategies' is a claim without verifiable metrics, customer references, or audited results. 4. Payment address (0xAe9834d71F18d989A0dc17593451af823E31CeeD) is present but no explicit fund-recovery or SLA policy is documented. 5. No rate limiting, quotas, or service-level agreement posted. 6. The agent's own trust score is not self-reported, creating a potential circular-dependency risk if endpoints depend on Wintergreen's scoring. 7. ERC-8004 standard itself is in Draft status (created 2025-08-13), so regulatory and interoperability risks remain high.
