# Explorer Gateway API — Bitcoin Cash Blocks

> Explorer Gateway API — Bitcoin Cash Blocks is a paid API for AI agents from api.blockchain.info, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-02).

Returns a paginated list of recent Bitcoin Cash blocks from the blockchain explorer, starting from the chain tip or a specified block height.

## 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-blocks-f9eec155 -d '<json body>'
```

Example prompt: Show me the last 20 Bitcoin Cash blocks from Blockchain.com's explorer, starting from block height 850000 and going back from there.

## When to prefer this

Choose this endpoint when you need a paginated list of Bitcoin Cash blocks from Blockchain.com's explorer — particularly useful for traversing BCH chain history, monitoring recent block production, or building analytics on block-level data. Prefer this over generic BCH node RPC calls when you want a hosted, pay-per-call REST interface without running your own node.

## Known failure modes

- Invalid 'after' cursor (non-existent block height) may return empty results or an error
- Limit exceeding 50 will be rejected or clamped
- Payment failure (x402 protocol) if USDC balance is insufficient — 402 response
- Network or chain data unavailability may return a 500 or timeout
- Malformed JSON body returns a 400 bad request
