# How Proofable fits together

> One account for identity, checks, agents, and access. Do not restart from zero in the next app.

Sign-in, gates, saved results, and agent authority share one account. Do not restart from zero in the next product.

## The loop

| Step | What happens                            |
| ---- | --------------------------------------- |
| 1    | Look up a saved result                  |
| 2    | Run a new check only if needed          |
| 3    | Save it on a profile                    |
| 4    | Reuse before access, payment, or action |

## Building blocks

| Piece                  | What it is                                                                |
| ---------------------- | ------------------------------------------------------------------------- |
| **Profile**            | Your Proofable account: identity, proofs, agents                          |
| **Sign-in and checks** | Runs on Proofable in the browser. Creates or refreshes a proof            |
| **Check**              | One trust decision ([catalog](../verification/verifiers))                 |
| **Proof**              | Portable reusable verification asset (`qHash` in the API)                 |
| **Listing**            | The access page you publish from Profile → Listings                       |
| **Gate**               | The published access rule (`gateId`) you embed; enforced with `gateCheck` |

MCP tools are named `proofable_*`. API paths and SDK exports keep their existing identifiers (`/proofs/`, `VerifyGate`). Buyer and docs prose use the terms above.
