## When to prefer this

Choose this endpoint when you need a pay-per-call, low-cost BTC price lookup settled in USDC on Base via x402 micropayments — ideal for autonomous agents that need to pay programmatically without API key management. Best for lightweight, infrequent price checks rather than high-frequency trading feeds.

## Known failure modes

- Payment failure: x402 micropayment not settled or insufficient USDC balance results in 402 Payment Required
- Network/service unavailability: hosted on Render free tier, may have cold-start latency or downtime
- Missing or malformed response: response schema is undocumented, so parsing errors are possible
- Rate limiting: high-frequency calls may be throttled or rejected

## 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 JSON object containing a numeric price value (e.g. USD spot price). The exact response schema is minimal; expect a price field or similar key-value pair representing BTC's current market price.
