## 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-stablecoin-flow-tracker-1895e6e8
```

Example prompt: Can you pull the current stablecoin flow data — I want to see where USDC and USDT are moving across chains and protocols right now?

## When to prefer this

Choose this endpoint when you need pay-per-call stablecoin flow data settled via x402 USDC micropayments on Base, and you want on-chain stablecoin movement metrics without a subscription. Best suited for crypto-native agents that can handle x402 payment flows natively. Prefer alternatives with documented schemas if data reliability is critical.

## Known failure modes

- 402 Payment Required if x402 USDC payment on Base is not attached or insufficient
- Empty or stub response due to undocumented schema and example-only response contract
- Service unavailable if Render.com hosting is down
- Ambiguous input schema may cause silent filtering or unintended data returns
- Rate limiting or access denial if payment not processed correctly

## 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 stablecoin flow data including transfer volumes, directional movements, protocol-level metrics, and on-chain stablecoin activity — the exact schema is minimal and example-only, so response shape may vary.
