## How to call it through Zero

```sh
zero fetch --capability yield-best-opportunities-by-address-1307c644
```

Example prompt: What are the best yield opportunities right now for my wallet 0xAbC123...def456 — show me the top pools ranked by APY across all supported chains with estimated gas costs and projected annual earnings.

## When to prefer this

Choose this endpoint when you need ranked, multi-chain DeFi yield recommendations tied to a specific wallet's actual holdings, including gas cost estimates and projected earnings — especially useful for agents automating yield optimization decisions across EVM-compatible chains using Pocket Network's public gateway.

## Known failure modes

- Invalid or malformed wallet address returns an error or empty result
- Address with no detected balances across supported chains returns empty chainsWithBalance and topOpportunities
- Upstream RPC or DeFi protocol data unavailable results in partial or stale data
- Payment not settled in USDC causes x402 rejection before query executes
- Address on unsupported chain returns no matching opportunities

## How this service works

Real-device, multi-region site verification with screenshot proof, live Pocket Network Shannon relay-demand/tokenomics/validator-security data, and on-chain RPC snapshots across 38 chains -- Ethereum, Solana, BSC, and peaq natively, plus 34 more EVM chains via Pocket Network's free public gateway (Arbitrum, Base, Optimism, Polygon, Avalanche, zkSync, Linea, Scroll, Gnosis, and more) -- 54 metered x402 routes, priced and settled per call in USDC. Migrating to Acurast decentralized cloud compute for censorship-resistant hosting -- stay tuned.

## Output

A JSON object containing the wallet address, a ranked list of top yield opportunities each with APY, pool name, protocol, chain, estimated gas cost in USD, and projected 12-month earnings in USD, plus a list of chains where the wallet holds balances with native token symbol and USD value.
