# Household Plant Fit > Filter a small sourced plant catalog by light, care effort and cat/dog listing. Compare twenty-four identified houseplants by light, space and care effort, with scientific-name aliases and species-specific ASPCA/RHS references. Part of usefulweb.app (https://usefulweb.app/). Part of [Hearth](https://hearth.usefulweb.app/) (ownerApp: hearth). Results are deterministic calculations from the inputs and the listed assumptions; the API returns exactly what the web page shows. ## Use it - Human interface: https://hearthplantfit.usefulweb.app/ (interactive tool at https://hearthplantfit.usefulweb.app/tool) - JSON API: POST https://hearthplantfit.usefulweb.app/api/v1/calculate with a JSON object of inputs (schema: https://hearthplantfit.usefulweb.app/api/v1/tool) - OpenAPI: https://hearthplantfit.usefulweb.app/openapi.json - MCP (Streamable HTTP): https://hearthplantfit.usefulweb.app/mcp - tool `hearth_plant_fit` ## Inputs - light (select): Light conditions - care (select): Maximum care effort - pets (boolean): Only ASPCA-listed non-toxic choices for cats and dogs - space (select): Space - query (text): Plant name or scientific alias ## Method - Catalog updated 2026-11-05: twenty-four identified species, species-specific ASPCA entries and linked RHS cultivation guidance. Scientific aliases preserve the scope of the source classification. - Bright means indirect light. Care effort and space categories are editorial filters, not measured requirements. Non-toxic is an ASPCA cat/dog listing; it does not mean edible or suitable for every animal. - Care reminders should prompt checking the plant and growing medium, not watering on a fixed schedule. The catalog is not an identification or ingestion-advice tool.
