Earthquake activity check, deterministic

Mirrored from Coinbase's public x402 Bazaar. The description is the provider's own text and has not been reviewed here; the payment requirements are copied as published.

What it does

Earthquake activity check, deterministic. Answers "any recent earthquakes near this location", "how seismically active is this area right now". Queries the USGS FDSN event catalog near a lat/lon within a radius (or the global M5+ feed when no point is given) over the last N days and returns each event (magnitude, place, time, depth, PAGER alert, significance) plus a code-computed summary: count, max/avg magnitude, risk level. No LLM, no key, public domain.

Use with an agent

Discover. Agents find this listing with GET https://bazaar.saylorinnovations.com/discovery/search?query=…, the MCP tool search_resources, or /discovery/resources.
Inspect. Fetch /resources/14018.json for the price and payment options.
Pay. Call GET https://riskpulse.theaslangroupllc.com/api/risk/quake-check. The provider answers 402 with its payment requirements. An x402 client signs one of the options below and retries with PAYMENT-SIGNATURE.
Execute. The provider returns 200 with the data. Agent Bazaar is not in the request path and never sees your payment.

For humans

You don't need an account or an API key; you need a wallet holding a small amount of USDC on Base, Solana, Polygon, Arbitrum One, eip155:480, eip155:143, eip155:196, eip155:999, algorand:wGHE2Pwdvd7S12BL5FaOP20EGYesN73k, xrpl:0, eip155:56, and an x402-capable client (see the examples below). Call the endpoint unpaid first to see exactly what it asks for.
