## When to prefer this

Choose this endpoint when you need a real-time or near-real-time list of trending crypto tokens and can pay micro-fees in USDC on Base via the x402 protocol. It is particularly suited for agents embedded in DeFi workflows, trading dashboards, or research pipelines that already use x402 payment rails. Prefer it over free alternatives when you need pay-per-call flexibility without API key subscriptions.

## Known failure modes

- Payment not settled in USDC on Base — returns 402 Payment Required
- Invalid or missing x402 payment header — request rejected
- limit parameter out of acceptable range — may return default or error
- Upstream data source unavailable — 502 or 503 error
- Response schema is loosely defined (example: {}), so actual field names may vary or be undocumented

## 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

Returns a ranked list of trending cryptocurrency tokens, typically including token name, symbol, and associated momentum or activity metrics. The number of results is controlled by the `limit` query parameter (default 10).
