# Reuse or verify (`proofable_verify_or_guide`)

> Reuse a saved Proof, or return the next step.

**Default reuse-or-verify tool.** Looks up existing proofs first. When signed in, ownership proofs continue with **`proofable_verify`**. A hosted link is returned only for outside login, payment, or a different account.

When signed in, **omit `walletAddress`** to use your profile wallet from `proofable_context`.

## What it does

1. Looks up existing proofs for the required verifiers
2. If satisfied → `already_verified` (continue silently)
3. If not, and signed in for an instant verifier → `next_action: call_proofable_verify` (no hosted link)
4. If not, and an outside step is required → one hosted link

Summarize the outcome for users as **Passed**, **Action needed**, or **Blocked**. Do not ask the user to open a browser unless this tool returned a hosted link.

## Input

`verifierIds` (required). Optional `walletAddress` when not signed in, `requireAll`, `chain`, `data`, and `options.returnUrl` (where to send the user after a hosted step).

```json theme={"dark"}
{
  "verifierIds": ["ownership-basic"]
}
```

## Output

`action` (`already_verified` | `verification_required`), `eligible`, `next_action`. `hostedVerifyUrl` only when a browser step is required.

After hosted completion, read proof state with **`proofable_proofs_get`**.
