## 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 explorer-gateway-api-bitcoin-cash-transaction-lookup-679919db -d '<json body>'
```

Example prompt: Can you look up the details for these Bitcoin Cash transaction IDs on Blockchain.com's explorer — I need to confirm they went through: a1b2c3d4e5f6..., b2c3d4e5f6a7...

## When to prefer this

Choose this endpoint when you need to look up Bitcoin Cash (BCH) transaction details specifically, especially in batch (up to 50 tx IDs at once), and want data sourced directly from Blockchain.com's trusted explorer infrastructure. Prefer this over generic blockchain APIs when BCH is the target chain and you need reliable, explorer-grade transaction data with a pay-per-call pricing model.

## Known failure modes

- Invalid or malformed transaction ID returns an error or empty result
- Requesting more than 50 transaction IDs exceeds the maxItems limit and may be rejected
- Non-existent BCH transaction ID returns no data or a not-found response
- Network timeout if the Blockchain.com explorer backend is slow or unavailable
- Payment failure via x402 protocol results in a 402 response and no data returned
