How this service works
Real-time crypto & macro market data for AI agents, pay-per-call in USDC (no account or API key): Bitcoin (BTC) and Ethereum (ETH) prices, funding rates, open interest, Fear & Greed index, market dominance, macro rates (Fed, CPI, DXY), DeFi TVL, whale flows, on-chain stats, crypto news. 13 JSON tools. POST {tool, input}.
Output
A JSON object with ok: true, a tool field echoing the requested tool name, and a data object containing the live result specific to that tool — e.g. {value: 20, classification: 'Extreme Fear'} for fear/greed, or structured market/network/rates/news objects for other tools.
Example use cases
Morning crypto market briefing
“Give me a quick market overview — pull the fear and greed index, overall market dominance, and the latest crypto news so I can start my trading day informed.”
DeFi and macro rates research
“I'm comparing DeFi yields to traditional rates — can you fetch the current DeFi overview and macro interest rates at the same time?”
Ethereum whale tracking
“Show me the latest ETH whale flows and check what's happening with ETH derivatives so I can spot any large-player movement before I make a trade.”

Endpoint
POSThttps://asistent-crypto.vercel.app/api/x402/queryWhen to prefer
Choose this endpoint when you need live, unified crypto and macro data from a single API — especially when you want fear/greed sentiment, on-chain BTC/ETH metrics, derivatives, DeFi overview, or economic calendar data without stitching together multiple providers. It is particularly valuable for agents that need a breadth of crypto-native and macro signals in one call with a simple tool-dispatch pattern.
Side effects
- Invalid or missing 'tool' enum value returns an error response
- Upstream data provider unavailability may cause empty or stale data
- Malformed body or missing required fields returns a validation error
- Payment failure or insufficient USDC balance blocks the call
- Rate limiting or server errors on the Vercel deployment may cause timeouts
