Park Lookup

Unified read API over US National Park Service developer.nps.gov.

Overview

Unified read API over US National Park Service developer.nps.gov. Pick a resource: parks (every NPS unit — historical parks, monuments, seashores, etc.), alerts (closures, dangers, info), campgrounds (NPS-operated campgrounds with reservation links), events (talks, walks, ranger programs), newsreleases (park news), thingstodo (activities by park), visitorcenters. Filter by parkCode (CSV — e.g. "acad,yose,grca"), state, or free-text query. Returns the upstream NPS payload verbatim (rich nested objects with images, addresses, operating hours, etc.).

Endpoint

Method	Endpoint	Price	Description

How to call it

Requests are paid per call over the x402 protocol. Call the endpoint, receive a 402 Payment Required quote, then repeat the request with the signed payment header. The SDKs do both steps for you.

# 1. Ask for a quote
curl -i https://api.jarvisclaw.ai/v1/marketplace/api/park-lookup

# 2. Pay it (the SDK signs and retries for you)
curl -H "X-PAYMENT: <signed-payload>" https://api.jarvisclaw.ai/v1/marketplace/api/park-lookup
