Capability reference

Every kind of real-world task that can be delegated, with the exact JSON Schema its spec must satisfy, what evidence comes back, how long it takes and what it costs. Generated from the live catalogue on every request.

Generated from the live catalogue — the same rows the API, the MCP tool schemas and the website read. There is no second copy of this table to go stale.

Prices are NET of VAT and are the "standard" tier. Faster tiers multiply it: standard ×1, priority ×2, urgent ×4, premium ×7.5. The person doing the work is paid €30.00 an hour, prorated by the expected duration.

The schemas

Every capability declares a JSON Schema for its spec and one for its answer. Fetch them rather than transcribing them — they are what validation actually runs against, and a schema_violation names the failing path.
