Beyond lookup
AI Workflows
With your catalog live in the MCP layer, agents do more than look things up — they reason across your APIs, draft integrations, and run multi-step workflows grounded in the real, current contracts.
Beyond lookup
From looking things up to getting things done.
Once your catalog is live over MCP, agents do more than fetch a spec — they reason across your APIs, draft integrations, and run multi-step workflows grounded in the real, current contracts. spec0 is the layer that keeps every step honest.
drafted the integration against both live contracts — ~620 tokens, no full-spec dump.
What it unlocks
Workflows that stay grounded in the spec.
Reason across APIs
An agent answering one question can pull from orders, payments, and auth at once — the registry resolves which operations matter, no one spec dumped in full.
Draft real integrations
Generate client code, handlers, and tests grounded in the live contract — correct field names, required headers, enum values, every time.
Stay correct as APIs evolve
Workflows read the current spec on each run. When an API changes, the agent sees it immediately — no re-pasting, no quiet drift.
