## When to prefer this

Use this endpoint when you need a high-level snapshot of the x402 payment protocol ecosystem — total participating services, volume estimates, and growth trends. Prefer this over manually querying individual facilitators or indexers when you want a single consolidated view. This is the only known aggregated x402 stats endpoint, making it uniquely suited for ecosystem-level reporting or dashboards.

## Known failure modes

- Payment not provided — returns 402 with payment instructions for both x402 and MPP methods
- Rate limit exceeded on demo mode — up to 10 free calls per IP per hour with ?demo=true
- Network or upstream data unavailability causing 5xx errors
- Stale or cached data if underlying aggregation pipeline is delayed
