How this service works
Public data and utility APIs paid per call in USDC on Base (x402). No accounts, no API keys. 174 routes: crypto/equity data, onchain reads, DNS/email/security intel, geo/weather, x402 payment diagnostics, dev utilities and more.
Output
Returns a JSON object with a count of monitoring series and an array of series objects, each containing: site ID, unit of measurement (e.g. ft3/s), parameter code, latest observed value, and parameter name (e.g. Discharge). Typically covers multiple USGS gauge stations per response.
Example use cases
River flood risk monitoring
“Check the current discharge levels from USGS water gauges so I can see if any rivers are running unusually high right now.”
Environmental research data pull
“Pull the latest USGS streamflow series data for me — I need the site IDs, parameter names, and current discharge values in ft3/s for my water quality report.”
Outdoor recreation flow check
“What are the current river flow rates according to USGS? I want to know if conditions are safe for kayaking this weekend.”

Endpoint
GEThttps://anibalb.duckdns.org/x402/usgs-water?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need real-time USGS streamflow or discharge data without setting up an account or API key, and are willing to pay $0.002 USDC per call via x402 on Base. Prefer it over direct USGS NWIS API calls when you need a frictionless, pay-per-use integration in an automated agent workflow. Best suited for spot checks and monitoring tasks rather than bulk historical pulls.
Side effects
- USGS upstream API unavailable — may return 502 or empty series array
- Payment not received or invalid x402 header — returns 402 Payment Required
- No active sites found — returns count 0 with empty series array
- Network timeout on duckdns host — returns connection error
- Malformed query params — returns 400 Bad Request
