Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 nimbus-onchain-data-api-x402-settlement-stats-acaf20f0
```

Example prompt: Pull the latest x402 settlement stats for the past 24 hours — I want total EIP-3009 settlement count, USD volume, and a breakdown of how much is attributed to known x402 facilitators.

## When to prefer this

Use this endpoint when you need a quick, pay-per-call snapshot of x402 and EIP-3009 on-chain settlement activity — including facilitator attribution — without committing to a subscription. Best suited for monitoring x402 network health, building dashboards, or conducting point-in-time research on x402 protocol adoption. Prefer alternatives if you need wallet-level data, historical time series, or guaranteed SLAs.

## Known failure modes

- Data pipeline lag exceeds 300 seconds — pipeline_fresh check fails
- Invalid window parameter value returns a 400 error
- Service hosted on Render free tier may be cold-started or unavailable, returning 503
- Payment not confirmed on-chain results in 402 response blocking data access
- Algorithmic estimates may be delayed or incorrect due to blockchain data indexing latency

## How this service works

x402 pay-per-call. Payments are per request in USDC and are final. No refunds on-chain. Service is provided as-is and may change or stop without notice. Informational data only, not financial, investment, legal, or tax advice. Metrics such as net transfer volume estimates and wallet clusters are algorithmic estimates from public blockchain data and may be wrong or delayed. Provided as-is with no warranty. Methodology: https://crypto-data-api-zo95.onrender.com/methodology.

## Output

A JSON object containing: estimated x402 settlement count, EIP-3009 settlement count and USD volume, share and count attributed to known x402 facilitators with per-facilitator breakdown, pipeline freshness check results, UTC generation timestamp, and a disclaimer string. All metrics are algorithmic estimates from public blockchain data.
