How this service works
22 agent-native micro APIs paid per call in USDC on Base via x402: funded bounty radar, honeypot trust scoring, token safety verdicts, crypto prices, multi-asset price snapshots, fear & greed index, full market-pulse snapshot, AI chat completion (Llama 3.1), crypto news, weather, web reader, ERC-20 balances. No accounts, no API keys — instant on-chain settlement.
Output
A JSON object containing: a UTC timestamp of the snapshot, the current Base blockchain network name and block number, a prices block with the count of symbols returned and an array of {symbol, price} pairs, and a sentiment block with the numeric Fear & Greed value (0-100) and its text classification (e.g. 'Greed', 'Fear', 'Extreme Greed').
Example use cases
Trading bot pre-trade market check
“Before placing any trade, pull me a market pulse snapshot with prices for BTC-USD, ETH-USD, and SOL-USD along with the current Fear & Greed score so I know whether the market is greedy or fearful right now.”
Morning crypto briefing for portfolio dashboard
“Every morning I want a quick crypto market summary — grab me current prices for BTC-USD, ETH-USD, SOL-USD, XRP-USD, and DOGE-USD along with the Fear & Greed index classification so I can see the mood at a glance.”
Alert trigger when sentiment spikes
“Check the current market pulse for BTC-USD and ETH-USD and tell me the Fear & Greed index value and classification — I want to know if we're in Extreme Greed territory so I can decide whether to trim my positions.”

Endpoint
GEThttps://mr-river5.makar52nn2016.workers.dev/api/market-pulse?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need prices AND sentiment in a single atomic call rather than making separate requests to a price API and a sentiment API. Ideal for trading bots, dashboards, or agents that need a holistic market snapshot at a point in time. Prefer over alternatives when you want no-account, no-API-key access with per-call USDC micropayment settlement on Base via x402. Use the default symbol set (BTC, ETH, SOL, XRP, DOGE) or supply up to 15 custom pairs.
Side effects
- Payment not received or insufficient USDC — returns 402 Payment Required
- Invalid or unsupported symbol in the symbols query param — may return partial results or error
- Too many symbols requested (over 15) — returns 400 Bad Request
- Upstream price feed or sentiment index unavailable — may return 503 or incomplete snapshot
- Malformed query string — returns 400 with parameter error
