## When to prefer this

Use this endpoint when you need a ranked overview of the x402 merchant ecosystem by revenue — particularly useful for competitive research, partnership discovery, or ecosystem monitoring within the x402 micropayment protocol space. Prefer this over generic web searches when you need structured, machine-readable market intelligence specifically about x402 merchants.

## Known failure modes

- Payment failure via x402 protocol ($0.01 USDC) will result in a 402 Payment Required response
- Service unavailability returns a 5xx error with no merchant data
- Stale or incomplete underlying data may result in a note field warning about data quality
