# Sess

> Sess lets an agent publish a page for a person on any device and receive the person's answer as a typed result bound to the exact page revision they saw. This is the public preview documentation; pages mark planned behavior with "Draft — lands with P1 increment N".

## Docs

- [Sess documentation](https://docs.sess.si/): Build an agent-to-person handoff with Sess: a no-signup quickstart, concepts, the generated API reference, limits, security and pricing.
- [Quickstart](https://docs.sess.si/quickstart/): Get a typed result from a person with curl and no signup, verify its signed receipt, then, with an API key, run a three-round Session.
- [Concepts](https://docs.sess.si/concepts/): Sessions, immutable Surface revisions, actions, Events and typed results, receipts, credential audiences, idempotency, revision conflicts, errors, expiry and revocation.
- [Limits](https://docs.sess.si/limits/): Request, content and interaction limits the Sess API enforces, the no-signup trial limits (including shared networks), and planned per-plan quotas.
- [API reference](https://docs.sess.si/reference/): Every implemented Sess API operation, schema and error code, generated from the OpenAPI contract.
- [Changelog and version](https://docs.sess.si/changelog/): What changed in the Sess API and pages, what is coming next, and how to check the contract and build you are using.
- [Security and access](https://docs.sess.si/security/): How Sess separates credentials, protects private human links, renders pages safely, and what it does not claim.
- [Retention and deletion](https://docs.sess.si/retention/): How long Sess keeps Sessions, trial results and links, when data is deleted, and what remains afterwards.
- [Pricing](https://docs.sess.si/pricing/): Sess pricing per resolved Session: a no-signup trial, a free workspace allowance and a paid pilot, invoiced manually. No overage charges.
- [Support and contact](https://docs.sess.si/support/): How to get help with Sess, what to include in a request, how to report a security problem, and how to check the running API version.
- [Onboarding feedback](https://docs.sess.si/feedback/): How Sess measures time to first typed result without analytics, and a plain-text template for reporting where the quickstart slowed you down.
- [Search the docs](https://docs.sess.si/search/): A filterable index of every Sess documentation page and section.
