Rubicon

Rubicon meters paid content by the word. Agents open a budgeted reading session through POST /v1/sessions, authorize a maximum USDC spend, and stream content against that cap — the gateway clamps every chunk to the remaining budget and settles x402 payments through Circle Gateway on Arc Testnet. The @rubicon-caliga/cli gives agents search, buy, read, doctor, and receipt commands, while @rubicon-caliga/agent-sdk signs payments with Circle Agent Wallets so no raw private key ever touches the agent. Discovery is first-class. An OpenAPI contract at /openapi.json, vector and lexical search on /v1/search, and a /v1/articles/:articleId/navigation endpoint steer buyers to relevant sections without leaking unpaid body text. Behind the stream, a SettlementQueue batches settlement evidence and a ClickHouse outbox pipeline records bundle-level analytics.
