## 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 scriptmasterlabs-btc-price-api-x402-e74e11dd
```

Example prompt: What's the current Bitcoin price right now? Use the ScriptMasterLabs x402 BTC price endpoint and pay the $0.001 USDC fee to get the live data.

## When to prefer this

Choose this endpoint when you need a quick, low-cost ($0.001 USDC) Bitcoin price lookup and your agent already supports x402 micropayment settlement on Base. It is best for lightweight, event-driven or infrequent BTC price checks rather than high-frequency trading infrastructure. Prefer alternatives like CoinGecko or Coinbase Market Data API if you need richer data, historical prices, or do not want per-call crypto payments.

## Known failure modes

- Payment failure or insufficient USDC balance — x402 payment not settled, returns 402 Payment Required
- Endpoint unavailability — hosted on Render free tier, may cold-start or be offline
- Empty or malformed response — response schema is undocumented, so field names and structure may vary
- Rate or quota issues — unclear rate limits may result in errors under high-frequency use

## How this service works

Pay-per-call crypto, RWA, federal, SEC, and compliance APIs. Settled in USDC on Base via x402. Hyphen routes only (e.g. /x402/rwa-aggregates, /x402/gas-tracker).

## Output

Returns the current Bitcoin price, likely as a numeric value with currency denomination (USD or equivalent), sourced at the time of the API call. Exact schema fields are minimal per the crawled metadata.
