## 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 usdt-supply-pulse-edge-agents-decision-intelligence-dd60ab1d
```

Example prompt: Can you pull the latest USDT Supply Pulse report from Edge Agents — I want to see the current supply trend, confidence rating, evidence sources, and any contradictions flagged in the data?

## When to prefer this

Choose this endpoint when you need a point-in-time, provenance-signed intelligence report specifically on USDT stablecoin supply with explicit confidence scoring and contradiction flagging — particularly for decision-support workflows where auditability and source traceability matter. Prefer it over generic crypto data APIs when you need bounded, evidence-backed findings rather than raw on-chain metrics.

## Known failure modes

- Payment not received — endpoint returns HTTP 402 if USDC payment is missing or malformed
- Stale or unavailable upstream data — report will state coverage gaps in the limitations field rather than failing silently
- Invalid request format — returns error if required parameters are malformed
- Service downtime — API may be temporarily unavailable during infrastructure issues

## How this service works

Point-in-time Ethereum USDT total-supply and 24-hour net-supply-change evidence from the approved crypto-flow store, with explicit baseline and freshness gating. Purpose: Measure observed USDT supply expansion or contraction on Ethereum without claiming cross-chain global USDT supply or transaction-level mint/redemption events. 10-minute freshness target; missing evidence is reported explicitly rather than invented.

## Output

A signed JSON report containing: a quality object with status and confidence rating, an analysis object with asset family, intent tags and a narrative summary, an evidence object listing covered assets and data policy, provenance with issuer URL and signed flag, a generatedAt timestamp, a disclaimer, known limitations, schema version, and a dataStatus field indicating report completeness.
