Policysupport.org's systems have an API (Application Protocol Interface) that allows them to be called from other software applications and return results to those applications. Use of the API is charged according to volume and type of use. The API gives access to results from the full processing functionality of the systems.
Two charging models are available: (a) the below per-use model or (b) a negotiated fixed annual fee model with imposed fair-use usage limits. Since our models and datasets are regularly updated and improved, we recommend that software applications call the API on each use rather than cache values locally.
|API Function||Features||Non-commercial use cost (per call)||Commercial use |
|Partners* cost |
|Return values for point||Returns values of any output map for user-defined point (latitude, longitude, WGS84) within a given tile. Values from multiple tiles incur a charge for each tile. Tile definitions described here.|| £0.01|| £0.02|| £0|
|Return values for (<1000) points in same tile||Returns values of any output map for list of user-defined points (latitude, longitude, WGS84) within a given tile. Values from multiple tiles incur a charge for each tile.|| £0.20|| £0.40|| £0|
|Return values for zone(s) of interest in same tile||Returns mean, sum, min, max values of any output map for each zone in a zone of interest map (values returned as table of numbers for each zone including ID and name of zone). Zones from multiple tiles incur a charge for each tile. Zonal maps listed here.|| £0.50|| £1.00|| £0|
|Return cached output map for tile ||Returns an already run (cached) output map as ARCASCII or PNG. Maps are cached if tile/model combination has been run before with current input dataset. If input datasets are updated then model needs to be re-run. Maps from multiple tiles incur a charge for each tile.|| £1.00 (zipped ARCASCII)|
|Run baseline required||When the baseline needs to be re-run to supply an output map, point, points or zone(s) then an additional run charge applies on a per tile basis.|| +£2.00|| +£4.00|| £0|
|Run baseline and scenario required||When the baseline and a scenario needs to be re-run to supply an output map, point, points or zone(s) then an additional run charge applies on a per tile basis.|| +£5.00|| +£10.00|| £0|
|Run tile for the first time required||When the baseline needs to be run for the first time ever to supply an output map, point, points or zone(s) then an additional run charge applies on a per tile basis.|| +£10.00|| +£20.00|| £0|
for further details.
Usage charges are applied on the basis of API calls received from your specified server IP address and using your unique API token.
*Partners work with us on a funded research project or collaboration (and that is our preferred resourcing model). Fair use limits apply to partners use of API calls.
