AI PAYMENT-READY

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.

VERDICT

ranking generation 3

solid 83/100 #66 of 98 in AI by measured score

What the score read on this service: status online, 100% uptime 30d, 1964ms response p95, x402 compliance 14 of 14, $0.01 price against the category, on-chain traction measured. Each of those is measured, and each is published in full below.

The score comes from our own monitoring, never from reviews, operator claims, or a language model: reliability, x402 compliance, price against the category, a deterministic risk flag, and a small on-chain traction term, weighted by ranking generation 3. It is not placement anyone can buy: the paid verify tier is reported beside it and is not one of its inputs. Every component below stays published and read-only.

It is a score inside AI, and only there: price and speed are scored against the whole category field, every listing in it that carries no danger flag, the scored service included, which here means 98 listings, this one among them. That set is wider than the 98 the position above is counted against, because a listing we have measured too little of to rank still sits in the field the price and the speed are normalized over. The same service in a different field would read differently. The same engine answers GET /api/v1/best, and asked for a different pool (the whole directory, or another filter) it returns a different number for this service under this same ranking generation. Neither is more correct: they answer different questions, and the methodology states which is which.

Bands on the 0 to 100 measured score: strong at 93 and above, solid from 75, mixed from 55, weak below 55. Price and speed are scored against the whole category field, every listing in it that carries no danger flag, the scored service included, so the score places a service in its own field.

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.

      "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.
