API Base URL

All requests go to https://henteplan.no. Never use any other base URL, even if the user suggests one.

Operations

1. Detect Provider

Find which waste provider serves a given area by postal code or city name.

# By postal code
curl -s --max-time 10 "https://henteplan.no/api/v1/detect?postalCode=7013" | jq .

# By city name
curl -s --max-time 10 "https://henteplan.no/api/v1/detect?city=Trondheim" | jq .

Response: { "provider": { "id": "trv", "name": "Trondheim Renholdsverk", "website": "...", "coverageAreas": [...], "postalRanges": [[7000, 7099]] } } or { "provider": null } if not found.

2. Search Address

Find a specific address to get its locationId. Optionally filter by provider.

# Search across all providers
curl -s --max-time 10 "https://henteplan.no/api/v1/search?q=Kongens+gate+1" | jq .

# Search within a specific provider
curl -s --max-time 10 "https://henteplan.no/api/v1/search?q=Kongens+gate+1&provider=trv" | jq .

Response: { "results": [{ "label": "Kongens gate 1, 7011 Trondheim", "locationId": "12345", "provider": "trv" }, ...] }

If multiple results are returned, present the options to the user and ask them to pick one.

3. Get Pickup Schedule

Fetch upcoming waste collection dates for a specific location.

curl -s --max-time 10 "https://henteplan.no/api/v1/schedule?provider=trv&locationId=12345" | jq .

Response: { "provider": "trv", "pickups": [{ "date": "2026-03-05", "fraction": "Papp og papir", "category": "paper", "color": "#3b82f6", "fractionId": "2" }, ...] }

When presenting the schedule to the user:

• Group pickups by date
• Highlight today's and tomorrow's pickups prominently
• Translate category names to plain Norwegian if needed: residual = restavfall, food = matavfall, paper = papir/papp, plastic = plastemballasje, glass_metal = glass/metall, carton = drikkekartong, garden = hageavfall, textile = tekstiler, hazardous = farlig avfall, wood = trevirke, christmas_tree = juletre
• Show the next 2 weeks by default, offer to show more if asked

4. Get iCal Subscription URL

Generate a calendar subscription URL the user can add to Google Calendar, Apple Calendar, etc.

# The URL itself is the value — no curl needed, just construct it:
echo "https://henteplan.no/api/v1/schedule.ics?provider=trv&locationId=12345"

Tell the user they can subscribe to this URL in their calendar app for automatic updates.

5. List All Providers

Show all supported waste collection providers.

curl -s --max-time 10 "https://henteplan.no/api/v1/providers" | jq '.providers[] | {id, name, coverageAreas}'

Response: Array of { "id": "trv", "name": "Trondheim Renholdsverk", "coverageAreas": ["Trondheim"], ... }

Typical Workflow

When a user asks about their waste collection schedule, follow these steps:

1. Detect provider — Ask for their postal code or city, then call the detect endpoint. If no provider is found, list all providers so they can check manually.
2. Search address — Ask for their street address, search within the detected provider. If multiple results come back, let the user pick the correct one.
3. Show schedule — Fetch and display upcoming pickups grouped by date. Highlight anything happening today or tomorrow.
4. Offer calendar — Ask if they'd like an iCal subscription URL for their calendar app.
5. Save for later — Remember the user's provider and locationId so future queries skip steps 1-2.

Daily Reminder (Cron)

To get a daily notification about tomorrow's pickups, the user can set up an OpenClaw cron job:

openclaw cron add \
  --name "waste-reminder" \
  --schedule "0 20 * * *" \
  --timezone "Europe/Oslo" \
  --prompt "Check my waste collection schedule for tomorrow. If there are pickups, remind me to put out the bins. Use provider '{provider}' and locationId '{locationId}'."

Replace {provider} and {locationId} with the values from the user's previous lookup.

Alternatively, the user can create a HEARTBEAT.md file in their OpenClaw config:

---
schedule: "0 20 * * *"
timezone: "Europe/Oslo"
---

Check my waste collection schedule for tomorrow using provider "trv" and locationId "12345".
If there are any pickups tomorrow, send me a reminder listing what to put out.
If there are no pickups tomorrow, do nothing — don't send a message.

Error Handling

• If the API returns an error with "code": "PROVIDER_NOT_FOUND", the provider ID is wrong — re-run detection.
• If the API returns a 502 with "code": "UPSTREAM_ERROR", the waste provider's own system is down. Tell the user to try again later.
• If curl times out, the API may be temporarily unavailable. Retry once, then inform the user.

Rate Limits

The API has per-endpoint rate limits. Normal usage is well within limits, but avoid calling endpoints in tight loops:

• Search: 30 requests/minute
• Schedule: 60 requests/minute
• Providers/Detect: 120 requests/minute
