The server is hosted: nothing to clone and nothing to run. Get a free key at onvexia.com/signup (then Account, API keys). During the launch offer every tool is free on an account. Without a key, one tool (get_data_coverage) answers, and every other tool replies with how to add a key or pay per call.

The problem this solves

If you trade or invest: by the time a coin is trending on your timeline, you cannot tell whether 40,000 mentions came from 40,000 people or 400 bots, whether the wallets buying are accumulating or are exchange hot wallets about to sell, or whether the account that called it has ever been right before. That information exists on-chain and in public posts. It is just not in one place at the moment you need it.

If you build with AI: an LLM asked about a token answers from training data months old, and — worse — cannot tell you when it *does not know*. A quiet market and a hole in its knowledge look identical in the answer you get back.

Onvexia gives both live measurements, and makes the answer say which is which.

What you can ask it

Once connected, these are ordinary questions in plain English:

Trading and research

• *"Is the hype around $TOKEN real, or is it bots?"*
• *"Which wallets moved the most ETH onto exchanges this week?"*
• *"Find coins under $100M market cap with rising social volume and a flat price."*
• *"What narratives is money rotating into right now?"*
• *"Show me new DEX pairs above $250k liquidity from the last 48 hours."*

Fundamental analysis and due diligence

• *"Give me the full fundamentals on $TOKEN — FDV, revenue, TVL, treasury, unlocks."*
• *"Is $TOKEN overvalued? Show market cap versus fully diluted valuation."*
• *"How much revenue does this protocol actually earn, and does it accrue to the token?"*
• *"How big is their DAO treasury, and how much of it is their own token?"*
• *"Has this protocol ever been exploited?"*
• *"What unlocks are coming for $TOKEN, and how concentrated are the holders?"*
• *"Does this AI-sector project actually ship code, against how much attention it gets?"*
• *"Are there SEC filings or court dockets naming this issuer?"*

Accountability

• *"Did this influencer call the move before it happened, or after?"*
• *"Rank the top crypto influencers by measured accuracy, not follower count."*
• *"Show me every call @rektcapital made on SOL and whether it came true at 7 days."*

Sanity checks

• *"What data do you actually have on this token?"*

What it does

Onvexia is a crypto research and market intelligence platform for traders, investors, analysts and AI agents. Find out whether a token's hype is real or manufactured, which wallets are quietly accumulating or dumping, which altcoins have social momentum building before the price moves, and whether the influencer calling it has ever actually been right.

Use it through any AI assistant (Claude, ChatGPT, Cursor) by connecting one URL, with nothing to install. Add a free Onvexia API key, or pay per call in USDC over x402 with no account.

Use Onvexia to:

▪ Check if crypto hype is real or bot-driven before you buy ▪ Spot pump-and-dump and coordinated shill campaigns while they are forming ▪ Track whale wallets, smart money and exchange inflows/outflows across 80,000+ labelled addresses ▪ Find trending altcoins early with social volume and sentiment from X/Twitter, Reddit, Farcaster and Bluesky ▪ Rank 2,300+ coins by Galaxy Score and AltRank, with the components behind every score ▪ Check whether a crypto influencer's calls came true — every call as a receipt linked to the original post, with the hit rate at 24h, 7d and 30d measured against holding BTC ▪ Run full crypto fundamental analysis on any token: market cap vs fully diluted valuation (FDV), tokenomics and supply schedule, protocol revenue, TVL, DAO treasury size and composition, exploit history, governance proposals, derivatives open interest, valuation ratios and a graded scorecard ▪ Do token due diligence before you buy: unlock schedules, holder concentration, competitive rank against peers ▪ Screen 2,300+ cryptocurrencies on social, on-chain and fundamental filters ▪ Find emerging DEX pairs and new exchange listings before they trend ▪ Query the entire dataset directly with read-only SQL

The MCP is public and read-only: connect with no install. To use the 66 tools, add a free Onvexia API key (sign up at onvexia.com; every tool is free on an account during the launch offer), or pay per call in USDC over x402 with no account at all.

Every response separates what was measured from what is not held. Sections carry a state, coverage counts ship alongside the results, and a null label means no label is held — never that a wallet or an influencer is safe. An empty list is never by itself evidence that nothing happened.

Galaxy Score and AltRank measure attention and social-market health. They are not valuation, price targets, or investment advice. Nothing here is a recommendation to buy or sell.

A real response from the live endpoint. The numbers move: the corpus grew by 1,376 posts between two runs an hour apart.

`get_data_coverage` is the tool to call first. It reports what is actually held right now, so an agent can tell a quiet market from a hole in the data before it reasons about either. There is also a pure-stdlib example in examples/quickstart.py.

All 66 tools

Every tool carries a title and readOnlyHint, and no description is shorter than 80 characters. That is enforced, not maintained: the server refuses to build if a tool is missing from TOOL_TITLES, and tests/test_tool_metadata.py asserts the rest by reading the surface back through list_tools() — the same call your client makes. Nothing here writes, and no tool can move funds.

A free API key, or pay per call with no account

With a free Onvexia API key, sent as the X-API-Key header, every tool is free during the launch offer. With no account at all, metered endpoints can be paid per call with x402 (USDC on Base, via Coinbase's CDP facilitator), so an autonomous agent can use paid data without a human ever creating an account:

export X402_CLIENT_PRIVATE_KEY=0x...   # a BURNER wallet, never a treasury key

$0.001 to $0.01 per call, published per endpoint in /.well-known/x402 and as x-payment-info on every priced operation in /openapi.json.

Three properties worth knowing before pointing it at mainnet:

• It pays at most once per request. A retry loop around a payment endpoint is a wallet-drainer; a second 402 is raised, not paid again.
• It refuses to overpay. The challenge is written by the *server*, so max_payment_atomic caps what one call can sign away.
• You are never charged for a failure. A response that is not 2xx is never settled — the signed authorisation simply expires.

Honest data, enforced

This is the part most data APIs get wrong, and it matters more for an agent than for a human — a human notices an empty chart, an LLM confidently summarises it.

• Sections carry a state: measured, not_held, or failed.
• Coverage counts ship with the results, not on a status page.
• A null label means *we hold no label*. It never means the wallet is clean.
• "We never looked" and "we looked and found nothing" are different values.
• Endpoints that cannot return data say so in the response — and are deliberately excluded from the paid catalogue rather than sold.

Run it yourself

You do not need to; the hosted endpoint is the supported path. This repository is the same server that runs it.
