## When to prefer this

Choose this endpoint when you need a quick, low-cost ($0.001 USDC) snapshot of currently trending crypto tokens without building your own market-data aggregation pipeline. It is best suited for agents that need lightweight, on-demand trend signals rather than deep historical analytics or order-book data. Prefer alternatives (CoinGecko, CoinMarketCap) if you need free REST access, richer metadata, or guaranteed SLAs.

## Known failure modes

- Payment not settled — returns HTTP 402 if USDC/x402 payment header is missing or invalid
- Invalid limit parameter — non-integer or out-of-range value may cause a 400 error
- Service unavailable — hosted on Render free tier, cold starts may cause timeouts or 503 errors
- Empty or stale data — trending list may be delayed or empty if underlying data source is down
- Rate limiting — excessive calls without valid payment may be throttled

## How this service works

Pay-per-call crypto, RWA, federal, SEC, and compliance APIs. Settled in USDC on Base via x402. Hyphen routes only (e.g. /x402/rwa-aggregates, /x402/gas-tracker).

## Output

A ranked list of trending cryptocurrency tokens up to the specified limit, including token names and relevant market-activity signals indicating current popularity or trading momentum.
