The era has arrived where AI agents call APIs, purchase data, and pay for services autonomously. In 2025, stablecoin transaction volume surpassed the combined totals of Visa and Mastercard ($33T). Coinbase unveiled x402 — embedding wallets directly into the HTTP protocol. Google launched AP2 (Agent Payments Protocol) as an open standard with 60+ partners, solving the trust problem in agent payments. The agent economy is no longer a future scenario.

This hub covers agent economy infrastructure — from technical layers (stablecoins, payment protocols, trust layers) to market dynamics (data marketplaces, micropayments). Pebblous is building core data infrastructure for this ecosystem.

Pebblous's agent economy positions:

  • AADS (Autonomous Agent Data Diagnostics) — A system where AI agents autonomously diagnose and improve data quality
  • Data Greenhouse — A data cultivation platform that grows and supplies high-quality synthetic data for agent training
  • PebbloSim — A physics-based digital twin simulator that generates physical AI training data
  • Physical AI Agent Data Marketplace — A marketplace where agents directly trade specialized datasets for robotics, autonomous driving, and manufacturing AI
