## 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 cambrian-x402-api-orca-pool-fee-ranges-a89265ec

Example prompt: What fee tiers are currently available on Orca's Solana liquidity pools? Pull the fee range data so I can decide which pool tier to use for my liquidity position.

## When to prefer this

Use this endpoint when you need up-to-date fee tier configuration data for Orca DEX pools on Solana, especially when building agents that need to select optimal liquidity pool fee tiers, compare DeFi trading costs, or route swaps through the cheapest available pool. Prefer this over manual RPC queries when you want pay-per-use access without managing infrastructure.

## Known failure modes

- Payment not included or insufficient USDC — returns 402 Payment Required
- Orca or Solana RPC data unavailable — may return 503 or empty array
- Invalid query parameters — may return 400 or unfiltered results
- Rate limiting if payment is not processed correctly

## How this service works

Pay-per-use blockchain and social data for autonomous agents.
