pitch31.aiAbout Pitch31
Pitch31 turns an API you already ship into a conversational agent your users can talk to, without you writing the agent layer. You upload an OpenAPI specification or a Postman collection, and Pitch31 reads the endpoints, parameters and auth requirements and builds an agent from them; the agent can then be left public or embedded directly inside your own product. The point of the product is the learning curve rather than the chat interface: instead of teaching users where a feature lives in your UI, they type what they want in plain language and the agent maps it onto the right sequence of calls. It supports typed input in over 130 languages. Agents chain multiple API calls together for a single instruction, hold authentication on the client rather than proxying credentials through Pitch31, and repair invalid payloads on the fly rather than surfacing a validation error back to the user. A worked example on the site walks a single prompt through creating a user in a CRM, sending a welcome email through Mailgun, creating a Stripe customer and granting dashboard permissions, showing each step's execution state. Users and roles are first-class, so an embedded agent can respect the same permission model the underlying API already enforces. Plans are metered in credits and API agents rather than seats.
