EVA MCP

AI PAYMENT-READY

payment-ready until 2026-08-20

Ask Eva: the autonomous research desk for crypto, DeFi and global markets, from the Everything.inc ecosystem. Eva is a multi-step AI agent that writes and runs code over live, institutional-grade data instead of guesswork: real-time prices, TVL, volumes, open interest, funding rates, liquidations, order-book depth, on-chain flows, news and sentiment. One paid call runs the ask tool and returns a plain-text answer.

Pay from $0.01 per request in USD Coin on Arbitrum One / Base, settled onchain via the x402 protocol, no signup, no API key needed.

Measured on the unpaid 402 handshake, not the paid call. A service can 402 correctly and still fail after payment.

No deterministic risk flag. Risk fires only on an exact blocklist match, or a reserved-brand name with a mismatched verified payTo. Never from low uptime, a high price, or a model guess.

Conservative undercount: only USDC settlements via facilitators we measure are counted. A measured floor, not an estimate.

Top buyer share is a concentration signal, not part of the ranking score.

      "description": "Ask Eva: the autonomous research desk for crypto, DeFi and global markets, from the Everything.inc ecosystem. Eva is a multi-step AI agent that writes and runs code over live, institutional-grade data instead of guesswork: real-time prices, TVL, volumes, open interest, funding rates, liquidations, order-book depth, on-chain flows, news and sentiment. This tool is stateless (no conversation history) and returns a plain-text answer only (no charts, images, or tables). Ask one self-contained question. Eva may take from ~30 seconds up to several minutes to answer, so you MUST set a request timeout of at least 10 minutes; a shorter timeout (e.g. 30 or 60 seconds) will abort the request before Eva can answer.\n\nCapabilities:\n- Deep analysis: in-depth coin, protocol, and market analysis, asset comparisons, and risk-focused, unbiased investment reasoning.\n- Asset recommendations: coins or assets worth considering right now, grounded in live data.\n- Signals (spot and leverage): entry levels, exit targets, and risk parameters. Optionally set a short-term timeframe up to 4 months out (today, tomorrow, the next N days, next week); the default is long term.\n- DeFi screening: rank and filter protocols and liquidity pools by TVL, 24h fees, APY, and yields.\n- Asset screening: rank and filter coins by 24h gains and losses, market cap, volume, open-interest change, funding rates, and more.\n- Market overviews: the overall market state and global market metrics at a glance.\n- News and events (crypto, stocks, macro): institutional-grade trending stories for a specific coin, a specific stock or company, the whole crypto market, or global macro and financial markets. Returns the top stories, each researched in depth with a summary, key facts, the true event date, traction (dominant, notable or emerging), and a worded sentiment, plus an overall news sentiment.\n- On-chain intel (whale radar): track Smart Money wallets, whale positions, what whales are accumulating, large holders, and entity or wallet lookups.\n- Liquidation maps: where forced liquidations sit for a coin, as key liquidation levels, zones, clusters and resting order-book walls, from intraday (24h) to big-picture (1 month) ranges, reported as price levels and magnitudes.\n- Token and protocol fundamentals: descriptions and key information about coins and protocols (e.g. 'tell me about X', 'what is X?').\n- Custom calculations and analysis: compute or aggregate any indicator, or run bespoke quantitative analysis (e.g. a complex regression), returning the results as numbers and text.\n- Portfolio tracking: summaries of your wallet holdings and positions. The wallet is identified from your account (API key) or, over x402, from the paying wallet.\n\nExample questions. Deep analysis: 'Recommend 3 coins'; 'Should I buy Hyperliquid for medium term profit?'; 'Give me entry levels and price targets for Chainlink for next week'; 'Run a regression of Solana returns against Bitcoin returns over the last 90 days and give me the beta and R-squared'; 'Give me an overview of the market'. Advanced screening: 'List the top 5 protocols by 24h fees'; 'Which of the top 500 coins have the best 24h gains?'; 'Which top 5 liquidity pools with a TVL of at least 10 million USD have the best APY?'; 'Over the last hour, which 5 coins have the highest open interest change?'. Intel & advice: 'Give me the latest Ethereum news and sentiment'; 'What is the latest news on Nvidia?'; 'What macro events are moving markets this week?'; 'Where are the liquidation zones for Bitcoin?'; 'What are whales accumulating?'; 'What are the latest whale positions?'; 'Tell me about Hyperliquid'; 'When is the next Federal Reserve FOMC meeting and what could be the impact on crypto?'. Portfolio: 'Give me a summary of my wallet holdings and positions'."

OVER TIME

All charts use the 30d selector; each series spans only the dates it has data for. Every series is also served as JSON at /api/v1/services/eva-mcp/price, /scores, /volume and /buyers. On-chain volume and distinct buyers are measured over the service's settlement address and are a conservative undercount (only settlements that reach a measured facilitator are counted). The on-chain series roll up hourly, so the latest day can be up to about an hour behind; distinct buyers are counted per payout address, so a service that settles to more than one address is an upper bound.
