## Known failure modes

- Unknown or unsupported asset symbol returns an error or empty result
- Asset has no active yield pools, returning no data
- Stale yield data if underlying protocol sources are not refreshed
- Payment failure via x402 protocol blocks the request
- Rate-limited or throttled responses under high load
