Returns the best available options (not yet personalized to a specific wallet's holdings).

Technical details
Endpoint
GEThttps://x402.ottoai.services/yield-recommendationsWhen to prefer
Use this endpoint when you have a specific EVM wallet address and want personalized yield vault recommendations tailored to that wallet's actual token holdings, rather than generic yield listings. Prefer this over general yield dashboards when the user wants to know which vaults are most relevant to what they already hold, with ranking across 80+ protocols.
Side effects
- Invalid or malformed EVM wallet address returns an error or empty recommendations array
- Wallet with no recognized token holdings returns an empty recommendations array
- Upstream vaults.fyi data unavailability causes degraded or empty results
- Payment failure (insufficient USDC) results in 402 response before data is returned
- Rate limiting or quota exceeded returns an error response
