Local POIs (Search API)

Paid Local POIs proxy via x402 pay-per-use (HTTP 402).

Prerequisites: This skill requires x402-payment. Complete the setup steps before first use.

Two-step flow: This endpoint requires POI IDs from a prior web search.

Call web-search with result_filter=locations to get POI IDs from locations.results[].id

Pass those IDs to this endpoint to get full business details

Endpoint (Agent Interface)

GET /api/x402/local-pois

Payment Flow (x402 Protocol)

First request -> 402 Payment Required with requirements JSON
Sign & retry with PAYMENT-SIGNATURE -> result JSON

With @springmint/x402-payment or x402-sdk-go, payment is automatic.

Quick Start (cURL)

Get POI Details

curl -s "https://www.cpbox.io/api/x402/local-pois" \
  -H "Accept: application/json" \
  -H "Accept-Encoding: gzip" \
  -G \
  --data-urlencode "ids=loc4CQWMJWLD4VBEBZ62XQLJTGK6YCJEEJDNAAAAAAA="

Multiple POIs with Location Headers

curl -s "https://www.cpbox.io/api/x402/local-pois" \
  -H "Accept: application/json" \
  -H "Accept-Encoding: gzip" \
  -H "X-Loc-Lat: 37.7749" \
  -H "X-Loc-Long: -122.4194" \
  -G \
  --data-urlencode "ids=loc4CQWMJWLD4VBEBZ62XQLJTGK6YCJEEJDNAAAAAAA=" \
  --data-urlencode "ids=loc4HTAVTJKP4RBEBZCEMBI3NG26YD4II4PATIHPDYI=" \
  --data-urlencode "units=imperial"

Note: POI IDs are opaque strings returned in web search locations.results[].id. IDs are ephemeral and expire after ~8 hours. The example IDs above are for illustration — fetch fresh IDs via web-search with result_filter=locations. Use --data-urlencode since IDs may contain =.

POI ID Cache & Invalidation

| Aspect | Policy | |--------|--------| | TTL | POI IDs are valid for approximately 8 hours from issuance. | | Invalidation | IDs cannot be refreshed or extended. After expiry, use web-search with result_filter=locations to obtain new IDs. | | Caching | You may cache POI details (hours, ratings, etc.) locally for display; do not cache IDs beyond 8 hours for reuse in local-pois or local-descriptions. | | Expired ID | Requests with expired IDs return empty or error results. Re-run the web search to get fresh IDs. |

Using with x402-payment

npx @springmint/x402-payment \

  --method GET

Parameters

Location Headers (Optional)

For distance calculation from user location:

Response Fields

Getting POI IDs

POI IDs come from the Web Search API (web-search) with result_filter=locations:

# 1. Search for local businesses
curl -s "https://www.cpbox.io/api/x402/web-search?q=coffee+shops+near+me&result_filter=locations" \
  -H "Accept: application/json" \
  -H "X-Loc-Lat: 37.7749" \
  -H "X-Loc-Long: -122.4194"

# 2. Extract POI IDs from locations.results[].id
# 3. Use those IDs with this endpoint

Use Cases

Local business lookup: Retrieve full details (hours, contact, address) for POIs surfaced in web search
Restaurant discovery pipeline: Search for restaurants, fetch POI details, filter by cuisine/rating/price_range
Business hours checker: Get opening_hours for a business to determine if currently open
Location-aware application: Combine with location headers to get distance calculations for nearby POIs

Notes

ID format: Opaque strings (use --data-urlencode for cURL)
Units: metric or imperial for distance measurement preference
Max IDs: Up to 20 IDs per request
