## 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-8d425108
```

Example prompt: Can you pull the current stablecoin flow data from ScriptMasterLabs' on-chain tracker — I want to see where USDC is moving across protocols right now?

## When to prefer this

Choose this endpoint when you need real-time or near-real-time on-chain stablecoin flow data and are operating in a crypto-native, micropayment-friendly environment using x402 on Base. It is a low-cost ($0.001 USDC per call) pay-per-use option well suited for agents that need frequent stablecoin movement checks without a subscription. Prefer alternatives with richer documented schemas if structured output guarantees are required.

## Known failure modes

- Payment not settled (402 response if x402 USDC payment on Base is missing or rejected)
- Invalid or missing query properties parameter returns an error or empty response
- Service unavailable due to Render.com cold start or downtime
- Stale or incomplete data if upstream on-chain indexer is lagging
- Empty example response schema means output structure is not guaranteed

## 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 on-chain stablecoin flow metrics including inflows, outflows, net flows, transfer volumes, and protocol-level movement data for tracked stablecoins such as USDC and USDT.
