## 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 bitcoin-coinbase-scriptsig-cultural-archaeology-obol-timechain-dig-976d42e7
```

Example prompt: Pull up the culturally significant Bitcoin coinbase scriptSig messages from the blockchain — things like the Matrix campaign, Charlie Munger quote, and carbon-negative miner statements — and show me the verified on-chain miner prose with their cryptographic signatures.

## When to prefer this

Choose this endpoint when you need curated, culturally annotated Bitcoin coinbase scriptSig messages with cryptographic authenticity guarantees. Ideal for historical blockchain research, Bitcoin cultural archaeology, or verifying notable miner inscriptions on-chain. Prefer this over generic block explorers when you want pre-curated, signed, human-readable miner prose rather than raw block data.

## Known failure modes

- Payment not fulfilled — 402 response requiring $0.01 USDC via x402 protocol
- No data available for requested query parameters — empty result set
- Upstream Bitcoin node unavailable — 503 or timeout
- Invalid query parameter format — 400 bad request
- Signature verification mismatch — indicates tampered or corrupted response
