# Market Intelligence API – Stablecoin Flows

> Market Intelligence API – Stablecoin Flows is a paid API for AI agents from api.marketintelligenceapi.com, paid per call via x402, $0.005/call, status unknown (last checked 2026-10-18).

Returns net USDC, USDT, USDT0, and USDG on-chain issuance (mint minus burn) over 24h and 7d per chain, an hourly 48h series, and a NET_ISSUANCE/NET_REDEMPTION signal indicating whether fresh dollars are entering or leaving crypto.

## 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 market-intelligence-api-stablecoin-flows-15d2775c
```

Example prompt: Pull the latest stablecoin flow data — I want to know the net USDC, USDT, USDT0, and USDG issuance over the past 24 hours and 7 days, broken down by chain, plus the hourly 48-hour series and whether the overall signal is net issuance or net redemption right now.

## When to prefer this

Choose this endpoint when you need a real-time, on-chain-derived signal of whether net new capital is entering or leaving crypto via stablecoin minting and burning. It is purpose-built for macro liquidity assessments across USDC, USDT, USDT0, and USDG simultaneously, with per-chain granularity and an hourly time series — making it superior to generic price APIs or exchange-volume endpoints that do not capture mint/burn dynamics.

## Known failure modes

- On-chain data lag: if a blockchain's RPC nodes are slow, the most recent mints/burns may not yet be reflected
- No query parameters documented — there is no way to filter by specific chain or stablecoin; full dataset is always returned
- Stale data: if the endpoint is called during a scheduled refresh window, values may lag real-time by up to an hour
- HTTP 402 Payment Required: if the x402 payment is not included or is insufficient, the call is rejected before data is returned
- HTTP 429 or rate-limit errors if called too frequently without adequate payment flow

## How this service works

Stablecoin flows, minting and redemptions: net USDC, USDT, USDT0 and USDG issuance (mint minus burn read on chain) for 24h and 7d, per chain, the hourly series of 48h and a NET_ISSUANCE/NET_REDEMPTION signal. Use to see whether fresh dollars are entering or leaving crypto.

## Output

Returns a JSON object containing: net issuance (mint minus burn) for USDC, USDT, USDT0, and USDG over 24h and 7d windows broken down per chain; an hourly time series covering the last 48 hours; and a discrete NET_ISSUANCE or NET_REDEMPTION signal indicating the current directional flow of capital into or out of the crypto ecosystem.
