{"ok":true,"host":"data.crestsystems.ai","status":"ready","manifest":{"positioning":"Crest Systems operates a paid market data API focused on current-state cryptocurrency and DeFi metrics. It serves agents that need a lightweight, multi-asset price snapshot, gas cost estimates for Base network transactions, trending asset discovery, or per-chain DeFi TVL breakdowns. It is distinct from full-featured data platforms in that it offers a small, focused set of snapshot endpoints rather than broad historical or streaming coverage.","host_overview":"data.crestsystems.ai provides snapshot market data for cryptocurrency assets and DeFi chains, covering current prices, gas fees, trending assets, and on-chain TVL metrics. All endpoints return point-in-time data with no streaming or historical time-series support. The host serves agents that need current-state inputs for decision-making, cost estimation, or market awareness.","routing_guidance":"Use this host when an agent needs current-snapshot cryptocurrency prices across multiple assets, gas fee tiers for Base network transactions, a ranked trending asset list, or DeFi TVL data for a specific chain. Do not use it for historical price queries, OHLCV time-series, real-time streaming feeds, or token swap execution — those require a dedicated historical data provider (e.g., CoinGecko Pro, Messari) or a DEX aggregator. Ethereum gas values from fetch-gas-prices may be null and should not be relied upon; use a dedicated Ethereum gas oracle if Ethereum gas accuracy is critical. The DeFi chain endpoint requires a chain name input and returns aggregate TVL, not live token prices or trade routes.","capability_clusters":[{"skill_names":["fetch-crest-price-feed","fetch-trending-crypto-assets"],"cluster_name":"Crypto Market Snapshots","cluster_summary":"Provides current price, market cap, volume, and 24h change for a broad list of cryptocurrency assets, plus a ranked list of currently trending assets with BTC-denominated prices."},{"skill_names":["fetch-gas-prices","fetch-defi-chain-data"],"cluster_name":"On-Chain Network Data","cluster_summary":"Supplies current gas price tiers for the Base network and per-chain DeFi TVL metrics including ranked protocol breakdowns and 24h TVL change."}],"cross_skill_workflows":[{"steps":[{"skill_name":"fetch-gas-prices","description":"Retrieve current fast/standard/slow gas prices in gwei for the Base network to determine transaction cost in ETH."},{"skill_name":"fetch-crest-price-feed","description":"Retrieve current ETH price in USD so the gwei-denominated gas cost can be converted to a USD estimate."}],"when_to_use":"Use when an agent needs to estimate the cost of a Base network transaction in USD terms before submitting it, requiring both current gas prices and a reference token price.","workflow_name":"Transaction Cost Pre-Check with Market Context"},{"steps":[{"skill_name":"fetch-defi-chain-data","description":"Retrieve total TVL and top protocol breakdown for the target chain to assess DeFi activity and capital concentration."},{"skill_name":"fetch-trending-crypto-assets","description":"Cross-reference trending assets against the chain's top protocols to identify whether trending tokens align with high-TVL DeFi activity."}],"when_to_use":"Use when an agent needs to assess a specific blockchain's DeFi ecosystem alongside which crypto assets are currently attracting market attention.","workflow_name":"DeFi Chain Opportunity Scan"}]},"model":"claude-sonnet-4-6","version_no":3,"generated_at":"2026-05-16T19:29:14.766Z","provenance":"ai_authored_unreviewed","ai_authored":true,"merchant_reviewed":false,"merchant_edited":false,"merchant_reviewed_at":null,"merchant_edited_at":null,"skill_md_url":"https://x402gle.com/servers/data.crestsystems.ai/SKILL.md","skills_url":"https://x402gle.com/servers/data.crestsystems.ai/skills.json"}
