Extend-only: never earlier, never on a gate that has already closed (a closed gate is never reopened), never on a gate with no end time. Saved as the next version of the gate's policy document; every other setting is unchanged. ## OpenAPI ````yaml /openapi.json post /gates-api/extend openapi: 3.1.0 info: title: BotShield API version: 2.0.0 description: >- The BotShield partner API. **BotShield Gate** — ask whether a live human is present (Human Gate) or over an age threshold (Age Gate). The person confirms with their passkey in the BotShield app and you receive a signed result. Partners learn *that* a user is human, never *who*. **Agents Ask** — your agent proposes an action, a verified human confirms or denies it, and BotShield signs a Proof of Resolution you can verify offline. **Gates API** — place and run gates and BotShield Actions from your server. **Verified Accounts** — a person links their account on your platform with a passkey; your server reads the status and the registry, and can unlink (revoke) an account with its API key. Every operation answers HTTP 200 with a `data` envelope; handler errors arrive as `data.error`. See the API overview and error reference. In the `botshield-sdk` package (2.2.1) these operations live under `client.census.*`, `client.verification.*`, `client.gates.*`, `client.securedAccounts.*` and `client.actions.*`. contact: name: BotShield Support email: support@botshield.ai url: https://botshield.ai servers: - url: https://api.botshield.ai/operations description: Production security: [] tags: - name: BotShield Gate description: >- Ask whether a present human (Human Gate) or a human over an age threshold (Age Gate) confirmed, and verify the signed result. - name: Gates API description: >- Place, open, extend and close gates, and place BotShield Actions, from your server with an API key that has the `gates:write` scope. - name: Verified Accounts description: >- Read and end the Verified Accounts on your platform from your server with your API key: status, the registry, and revoke (unlink). - name: Agents Ask description: >- Your agent proposes an action; a verified human confirms or denies it in the BotShield app; you receive a signed Proof of Resolution. paths: /gates-api/extend: post: tags: - Gates API summary: Extend a gate's window description: >- Move a placed gate's closing time later.
