## 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 stablecoin-mint-burn-monitor-usdc-usdt-8fce9e08 -d '<json body>'
```

Example prompt: What's the net stablecoin flow over the last 24 hours — how much USDC and USDT was minted vs burned on Ethereum and Base, and what's the largest single operation?

## When to prefer this

Use this endpoint when you need a real-time macro signal of stablecoin supply expansion or contraction (mints vs burns) on Ethereum and Base, specifically for USDC and USDT. Prefer it over generic blockchain explorers when you want pre-aggregated totals, counts, and net flows without writing your own contract event queries. Ideal for trading signals, DeFi dashboards, or macro crypto analysis.

## Known failure modes

- Invalid 'horas' value outside 1–48 range returns error or empty result
- RPC node latency may cause incomplete block coverage for recent hours
- On-chain data lag means the most recent blocks may not be fully indexed
- Missing or malformed body returns schema validation error

## How this service works

Stablecoin mints and burns over the last hours read from the contracts: USDC and USDT on Ethereum and USDC on Base, with totals, counts, largest operations and net flow. A signal of money entering or leaving crypto.

## Output

A structured JSON response containing per-stablecoin breakdown (USDC Ethereum, USDT Ethereum, USDC Base) with: emission totals, burn totals, operation counts, largest single operation, net flow (neto), hours covered, blocks reviewed — plus a global neto_total_usd and metadata (source, reading timestamp, notes).
