AI agent identity is fragmented. Developers choosing a trust provider in 2026 must weigh standards (ERC-8004), payment rails (x402, subscription), compliance (EU AI Act), and operational features (free tier, marketplaces). SoulLedger is the only provider that unifies all ten categories.

x402 on Base L2 — a 99%+ margin product engineered specifically for high-volume agentic consumption. Same audited EU27 HS2
eu-trade.db, fractional pricing.
