$0.050
per call · one payment for the whole workflow

3 tools run server-side in one request. You pay once, settle once, and get a single response - no orchestration, no per-step payments, and a partial-success envelope if any step fails. USDC over x402 on any supported chain.
When to use this pack
An agent needs to answer 'what's happening in crypto right now?' without making 3 separate calls. Covers the price-check + market-context combo agents buy most.
Tools in this pack
All 3 run inside the single $0.050 call above. Each is also callable on its own if you only need one part.
- Crypto price GET /api/crypto-price Live crypto prices for one or many coins in any vs_currency (usd, eur, btc, eth, etc). Returns last price, 24h change %, 24h volume, and market cap per coin. The simplest crypto price read - for ranked market-cap tables use crypto-market, for candles use crypto-history, and when you need an oracle-grade price with a confidence interval use price-pyth. Accepts ticker symbols (BTC, ETH, SOL) for the top ~50 by market cap, or canonical CoinGecko ids (e.g. "render-token") for any of the ~15k tracked coins. Batched: up to 25 coins per call. Backed by CoinGecko's public API - keyless.
- Crypto trending GET /api/crypto-trending Trending coins on CoinGecko in the last 24 hours, ranked by user search activity on the site (currently ~15 results). Includes coin id, symbol, market cap rank, current price (BTC-denominated), and score. Useful signal for detecting narrative shifts before they hit price charts.
- Crypto global market GET /api/crypto-global Global crypto market snapshot: total market cap, total 24h volume, BTC dominance, ETH dominance, active coin count, active exchange count, and 24h market-cap change %. Returned in a chosen vs_currency (default usd). Backed by CoinGecko /global.
Workflow
- Get the live price, 24h change, market cap, and volume for the requested coin via crypto-price.
- Pull the top trending coins from crypto-trending - what the market is paying attention to right now.
- Get global market stats from crypto-global - total market cap, BTC dominance, 24h volume, active coins.
