## 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 phantom-api-avalanche-nft-sales-9972b57a -d '<json body>'
```

Example prompt: Pull the last 50 NFT sales on Avalanche for contract address 0xABC123... ordered from newest to oldest.

## When to prefer this

Choose this endpoint when you specifically need NFT sales data on the Avalanche blockchain with flexible block-range filtering and per-call pay-as-you-go pricing via x402 USDC micropayments, rather than a subscription-based indexer. It is ideal for agents that need sporadic or targeted historical sales queries without committing to a monthly API plan.

## Known failure modes

- Invalid or missing contractAddress may return empty results or an error
- fromBlock greater than toBlock returns an error or empty set
- Unsupported block range (too large) may result in timeout or truncated results
- Malformed contract address format returns a validation error
- Exceeding rate limits or payment failure via x402 returns a 402 Payment Required error
- Network congestion or RPC node issues may cause delayed or failed responses
