How this service works
API and MCP servers that let AI agents and apps check people, companies, Dutch addresses and cars against official records: sanctions and PEP lists, 10 company registers, Dutch property, rent and RDW vehicle data. From $0.001 per call.
Output
Returns annual flood probabilities for the address (any flooding, over 20cm, over 50cm, over 200cm), climate-adjusted projections for 2050 and 2100 scenarios, the modelled worst-case water depth, and the ground elevation in metres above sea level (AHN). Data sourced from Rijkswaterstaat's LIWO system.
Example use cases
Mortgage climate risk screening
“Before we approve this mortgage, check the flood risk for the property at postcode 2512HM, house number 42 in The Hague — I need the annual flood probability at different water levels and what the 2100 climate scenario looks like.”
Insurance underwriting flood assessment
“I'm pricing home insurance for a property at postcode 1011AB, house number 5 in Amsterdam — what's the LIWO annual flood probability there, including the chances of water exceeding 20, 50, and 200 cm?”
Relocation physical risk check
“We're thinking of buying a house at Keizersgracht 123 Amsterdam, postcode 1015CJ — can you pull the flood risk data including worst-case water depth and how high the ground is above sea level?”
Technical details
Endpoint
GEThttps://factline.dev/v1/flood-risk?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need official Dutch government-sourced (Rijkswaterstaat LIWO) flood risk data for a specific Netherlands address, including granular annual probabilities at multiple water depth thresholds and forward-looking climate scenarios. Prefer it over generic European flood APIs when the address is in the Netherlands and you need AHN ground elevation, 2050/2100 projections, or worst-case depth modelling for real estate, insurance, mortgage, or ESG purposes.
Side effects
- Invalid or non-existent postcode format returns validation error
- House number not found at postcode returns no-match or empty result
- Address outside the Netherlands returns out-of-scope error
- LIWO data unavailable for very rural or newly constructed addresses
- Missing required postcode or house number parameters returns 400 error
