How this service works
Pay-per-call BTC/ETH briefs via x402
Output
A JSON object containing the timestamp, asset name (BTC), current price in USD, RSI-14 value, an integer directional score, a signal string (e.g. 'bullish' or 'bearish'), and a disclaimer that the output is informational only.
Example use cases
Quick BTC sentiment check
“Pull the latest Bitcoin signal for me — I want to see if it's bullish or bearish, the current price, and the RSI-14 reading.”
Automated trading alert monitor
“Every hour, check the BTC signal endpoint and alert me if the signal flips from bullish to bearish or the RSI-14 drops below 30.”
Pre-trade technical brief
“Before I make a move on Bitcoin, give me the current BTC price, RSI, and directional score so I can see what the technicals look like.”

Endpoint
GEThttps://x402-research-iota.vercel.app/api/signal/btc?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, low-cost ($0.003 USDC) BTC-specific technical snapshot — price, RSI-14, and a pre-computed directional score — without building your own indicator pipeline. Ideal for agents that need a quick bull/bear signal on Bitcoin before executing a decision or surfacing a market brief to a user. Use the multi-asset sibling endpoint if you need signals for more than one cryptocurrency in a single call.
Side effects
- Payment not provided or rejected — endpoint returns HTTP 402 requiring x402 micropayment
- Stale or unavailable market data — price and RSI may lag if upstream data source is delayed
- Invalid or missing asset path — endpoint only covers BTC at this URL; other assets require sibling endpoints
- Network or Vercel cold-start timeout — may return 5xx on first invocation after idle period
