# Science Earthquakes Feed – x402 Pay-per-Call

> Science Earthquakes Feed – x402 Pay-per-Call is a paid API for AI agents from workspace-x402-paywall.onrender.com, paid per call via x402, $0.005/call, status unknown (last checked 2026-10-11).

Returns recent significant earthquakes filtered by minimum magnitude, paid via x402 micro-payment at $0.005 USDC per call.

## Facts

- Endpoint: GET https://workspace-x402-paywall.onrender.com/science/quakes?utm_source=zero.xyz
- Price: $0.005/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-11
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/science-earthquakes-feed-x402-pay-per-call-ad936dc7

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 science-earthquakes-feed-x402-pay-per-call-ad936dc7
```

Example prompt: Pull the latest significant earthquakes — magnitude 6 or higher — and include just the name, location, and magnitude fields.

## When to prefer this

Choose this endpoint when you need live or near-live earthquake data filtered by magnitude and want to pay micro-amounts per call in USDC via x402 without a subscription. Ideal for agents doing one-off seismic lookups, monitoring dashboards that poll periodically, or research workflows needing structured earthquake data without a free-tier API key setup.

## Known failure modes

- Payment not received or invalid x402 USDC payment → 402 Payment Required
- Invalid 'min' value (non-integer or out of range) → 400 Bad Request
- Requested fields not available in dataset → partial or empty field values
- Upstream USGS data unavailable → 503 or empty result set
- No earthquakes found matching the magnitude threshold → empty events array

## How this service works

66 pay-per-call APIs: AI text/image generation ($0.01), Polymarket odds, crypto prices, DeFi yields, FX rates, weather, IP/geo, FBI wanted, SEC tickers, clinical trials, 250M academic papers, Stack Overflow, meme-coin launchpads (pump.fun, Clanker, Four.meme, SunPump), tokenized stocks, Solana top 100, and 40+ more. $0.005/call standard. USDC on Base and Solana via x402.

## Output

A JSON object containing a list of recent earthquake events matching the minimum magnitude threshold, with fields such as event name, magnitude, location, depth, and timestamp (fields may be filtered by the comma-separated 'fields' parameter).
