Keryx
🥇 Lepton Awards · 1st place ✨ standaloneKeryx makes citation itself the payment event. An autonomous reading agent in lib/agent/run-agent.ts decomposes a question, discovers sources, and decides BUY, SKIP or CACHE per source with a plain-language rationale, paying an x402 toll for each paid read. After synthesizing a cited answer it weighs each source's real contribution and settles weighted USDC micropayments to creator wallets, with multi-author splits from lib/payments/split-allocation.ts. Browsers co-sign under a funded, non-custodial spending cap via lib/payments/browser-cosign-gateway.ts, and lib/payments/client-payto-allowlist.ts checks every payee against on-chain registry authority. Creators register sources through SourceRegistry (contracts/source-registry.sol), deployed and source-verified on Arc mainnet at 0x42a64061b6cd84067bb660b2a9b8aa881fd225bb. Crossref and arXiv originals are read natively, and reports export to Markdown, BibTeX, RIS and CSL-JSON via lib/research-citation-export.ts. The keryx-mcp package under mcp/ brings the buy-read-cite-settle loop to any MCP client with caller-funded payments, beside a Tauri desktop app, a Chrome extension and chat adapters for Discord, Slack and Telegram.
