B3
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.
B3 publishes 72 APIs on the APIs.io network, including Action API, Actions API, Admin API, and 69 more. Tagged areas include Company, Crypto, Blockchain, Web3, and Workflow-Automation.
The B3 catalog on APIs.io includes 1 event-driven AsyncAPI specification.
B3’s developer surface includes authentication, sandbox, documentation, API reference, quickstart, pricing, engineering blog, and 24 more developer resources.
