aid: b3
name: B3
description: 'B3 is an onchain economy platform founded by former Coinbase leaders, operating an EVM-equivalent Layer-3 gaming
  and payments chain settling to Base. B3 ships across three engines: Labs (products such as Basement/Bsmnt, HypeDuel, AnySpend,
  XCade and B3AR), B3OS (a credit-based, no-code automation platform for cross-chain workflows), and Holdings (strategic investments).
  For developers B3 exposes the B3OS Workflow API (workflows, triggers, actions, runs, connectors, outbound webhooks and an
  x402 payment surface), a free public B3 Data API (Blockscout + Thirdweb Insights indexed onchain data), a Profiles API for
  aggregated onchain identity, and Global Accounts SDKs. B3 was surfaced as a portfolio company of Pantera Capital and enriched
  into the API Evangelist network.'
