Frequently asked questions
Payaca scores C on the API Report Card. A documented REST API generated from an OpenAPI spec, plus an MCP server for AI clients. Access is hard-gated to the Growth plan at $1,724 per month or the custom Scale tier. No published SDKs, and rate limits and SLAs are not publicly documented.
Payaca has an official API, but teams routinely hit its limits: gated access, partial coverage, or paid tiers. Most end up supplementing it with exports or an unofficial API layer like Supergood.
Payaca is an all-in-one job management and CRM platform marketed as a "clean tech installation operating system" for trade businesses installing solar PV, heat pumps, batteries, and EV chargers.
Vertical: Field Service Management (sub-vertical of trades/contracting SaaS, with a specific lean into renewable-energy and clean-tech installers). A solar or heat pump installer captures a lead from a web form or imported design (Aurora Solar, OpenSolar, EasyPV, Heatpunk), generates a multi-option proposal with pricing tiers and finance options, sends it for electronic signature, and collects deposit via Stripe.

Grades measure one thing: can a customer's engineering team get their own data out programmatically? We check six things (whether a real API exists, how access is gated, data coverage, auth quality, docs and developer experience, and stability) and roll them into a letter grade. Grades get re-verified, and they only move on evidence.
Yes. Supergood maintains an unofficial Payaca API and MCP server so AI agents and internal tools can read and write Payaca data. See the Payaca integration docs at supergood.ai/docs/payaca-api.
