## When to prefer this

Use this endpoint when you need fast, no-signup, pay-per-call access to live cryptocurrency market data (prices, market caps, volumes, rankings) sourced from CoinLore's public API. Ideal for AI agents that need crypto market snapshots without managing API keys or subscriptions, and when you want to pay only per successful call via USDC micropayments.

## Known failure modes

- Upstream CoinLore API unavailable — no data returned
- Invalid limit parameter (must be 1–100) — request rejected or defaults applied
- Payment failure — call not charged, no data returned
- Rate limits or network timeouts from Cloudflare worker layer

## How this service works

CoinLore ranked crypto list: USD price, market cap, 24h volume and 1h/24h/7d changes for the top N coins (N from 1 to 100).

## Output

Returns a JSON object with an array of coins, each containing: coin ID, name, rank, symbol, price in USD, market cap in USD, 24h volume in USD, 1h/24h/7d percentage price changes, and circulating supply. Also includes the total count returned and the data source URL and timestamp of when it was checked.
