How this service works
x402 pay-per-call crypto trading intelligence for AI agents. Get live Bitcoin/ETH/SOL BUY/SELL/HOLD signals with support/resistance, volatility regime, risk, edge_score and invalidation — not raw CoinGecko dumps. Price: 0.01 USDC on Base per call. Best value: compare up to 5 coins + vs-BTC strength in one payment. Free routes use security: []. Paid routes require x402 (PAYMENT-SIGNATURE / X-PAYMENT) after HTTP 402. Free tease: GET /api/preview?q=btc (price only). Docs: /llms.txt.
Output
Returns a structured, LLM-ready text brief containing side-by-side price data, technical analysis indicators, and relative performance summaries for the requested coins, formatted for easy consumption by AI agents or language models.
Example use cases

“Compare BTC, ETH, and SOL for me — I want to see their current prices and technical indicators side by side so I can decide which to overweight this week.”
Altcoin head-to-head analysis
“Do a head-to-head comparison of AVAX and MATIC — price performance and technical analysis — I'm trying to figure out which one looks stronger right now.”
AI agent crypto briefing

Endpoint
GEThttps://price-bot-production-4d6a.up.railway.app/api/compareWhen to prefer
Choose this endpoint when you need a ready-to-use, LLM-formatted brief comparing two or more cryptocurrencies in a single call, especially for AI agent workflows where the output needs to be ingested directly without further parsing. Prefer it over raw price APIs when you want technical analysis and narrative summary bundled together, and over general market data feeds when you need low-cost, per-call micropayment pricing via x402 on Base.
Side effects
- Invalid or unrecognized coin symbols return an error or empty result
- Too many coins in a single request may cause timeouts or malformed output
- Payment not fulfilled via x402 returns a 402 Payment Required response
- Unsupported format value may cause fallback to default formatting
- Market data source outage may return stale or incomplete data
