# CryptoPulse Research Snapshot

> CryptoPulse Research Snapshot is a paid API for AI agents from cryptopulse.theaslangroupllc.com, paid per call via x402, $0.25/call, status unknown (last checked 2026-09-14).

Returns a deterministic crypto market snapshot including BTC/ETH price, 24h change, market cap, BTC dominance, total market cap, and Fear & Greed sentiment index — no LLM narrative, raw data only.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability cryptopulse-research-snapshot-eefd027e
```

Example prompt: Give me a quick crypto market snapshot — I want the current BTC and ETH prices, their 24-hour changes, BTC dominance, total market cap, and today's Fear and Greed sentiment number.

## When to prefer this

Choose this endpoint when you need raw, deterministic crypto market data at minimal per-call cost ($0.25). Ideal for agents with strict per-call spend caps, high-frequency polling loops, or situations where narrative interpretation is not needed. Prefer the $0.50 /api/research-brief sibling if you also need regime calls, derivatives data (funding rates, DVOL, options skew), on-chain flows, or macro-event probabilities.

## Known failure modes

- Payment not received or x402 payment validation failure — endpoint returns 402 with payment requirements
- Upstream market data feed outage — may return stale data or a 503 error
- Rate limiting if called too frequently from same client
- Network timeout if data provider is slow to respond

## How this service works

Deterministic, data-only crypto snapshot: BTC/ETH price, 24h change, market cap, BTC dominance, total market cap, and Fear & Greed sentiment. No LLM, no narrative — a $0.25 preview tier for agents with small per-call spend caps. Includes an upsell pointer to the $0.50 /api/research-brief for regime calls, catalysts, derivatives (funding/DVOL/skew), on-chain flows and macro-event odds.

## Output

A structured JSON snapshot containing: BTC price (USD), ETH price (USD), 24-hour percentage change for both, individual and total cryptocurrency market capitalizations, BTC dominance percentage, and a Fear & Greed sentiment score/label. No narrative text or LLM-generated interpretation is included.
