## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability yruz-crypto-fees-estimator-feeed583 -d '<json body>'
```

Example prompt: What are the current estimated transaction fees for the Jupiter router on Solana?

## When to prefer this

Use this endpoint when you need a quick, inexpensive fee estimate for Solana transactions, especially for the Jupiter DEX router or other Solana programs. Prefer this over on-chain RPC calls when you want a simple REST API abstraction for fee lookups without managing Solana node connections.

## Known failure modes

- Invalid or malformed Solana account/program address returns an error
- Solana RPC unavailability may cause lookup failure
- Empty result object if fee data is temporarily unavailable
- Payment not processed (x402 payment required before response is returned)
