aid: llama-box name: Chado Studio description: >- Chado Studio (contact api@chado.studio) operates llama.box, a desktop-style hub for the Curve Finance ecosystem — dashboards, analytics and curated links for Curve, crvUSD, LlamaLend, YieldBasis, Convex, Stake DAO, Yearn and Resupply. Its one machine-readable surface is the crvUSD Yield Optimizer, a FastAPI service mounted at https://llama.box/yo that discovers crvUSD yield across scrvUSD, LlamaLend, Convex and StakeDAO on Ethereum, Arbitrum, Base, Optimism and Fraxtal, scores pool risk 0-100 and simulates rebalances. It publishes an OpenAPI 3.1.0 contract (10 operations) at /yo/openapi.json with Swagger UI and ReDoc, an A2A 0.2.5 agent card at /yo/.well-known/agent.json declaring four skills, and charges for the risk, rebalance and A2A calls per request through the x402 protocol in USDC on the Base Sepolia testnet. The hub itself serves an llms.txt and a robots.txt that allows every major AI crawler. url: https://raw.githubusercontent.com/api-evangelist/llama-box/refs/heads/main/apis.yml image: https://llama.box/og-cover.png x-type: company x-source: harvest:a2a-registry x-tier: profiled x-tier-reason: enrichment pass 2026-09-19 (local-v3; was a2a-registry harvest stub) specificationVersion: '0.20' created: '2026-09-19' modified: '2026-09-19' tags: - Agents - A2A - x402 - DeFi - Yield - Curve Finance - crvUSD - Stablecoins - Risk Scoring - Analytics - Agent-Native tags_raw: - Agents - A2A - x402 - DeFi - Yield - Curve Finance - crvUSD - Stablecoins - Risk scoring - Analytics - Agent-native - agent-native apis: - aid: llama-box:crvusd-yield-optimizer-a2a-agent name: crvUSD Yield Optimizer A2A Agent description: >- Agent2Agent surface of the same service: an agent card at https://llama.box/yo/.well-known/agent.json (protocolVersion 0.2.5, version 1.1.0, provider "Chado Studio") declaring four skills — Best Yield Finder, Pool Discovery, Risk Assessment and Rebalance Advisor — that accept natural-language or structured DataPart input.

The card's own url (https://llama.box/yo) is not the RPC endpoint and 404s on GET and POST. image: https://llama.box/og-cover.png humanURL: https://llama.box/yo/docs baseURL: https://llama.box/yo/a2a tags: -
