Every endpoint in the OpenAPI 3.1 description
Self-serve API keys, no human approval step
Card vaulting and best-rail routing
Versioned surface with a six-month deprecation notice
Nothing. The MCP server is free and reads require no authentication, so an agent can discover the surface and call it without a payment method on file.
When will API pricing be published?
Soon. It will be usage-based, and this page is the canonical place it will appear. If you need numbers before then, use the contact form or email team@onetext.com and we will share current pricing directly.
Will I be charged without warning?
No. There is no billing today, and API pricing will be announced here before it takes effect. Interface changes follow the published versioning policy, which guarantees six months of notice before anything is removed.
