## Change Feeds
All high-frequency datasets support `?since=ISO8601` change feed queries, returning only records updated after the given timestamp. Your agent can poll efficiently without re-fetching unchanged data.
## Payment
Verilex uses the [x402 protocol](https://x402.org) for pay-per-query access with USDC on Base chain. Free endpoints (stats, samples) work without payment. Paid endpoints return HTTP 402 with payment requirements.
## Data Freshness
Every paid response includes headers:
- `X-Data-Stale: true|false`
- `X-Data-Last-Updated: ISO 8601 timestamp`
- `X-Data-Age-Seconds: number`
## Environment Variables
| Variable | Description |
|----------|-------------|
