客户端无法启动 OAuth 时的后备入口。返回浏览器注册链接。本工具不创建账号，不接收密码，也不代用户同意条款。 Fallback when the client cannot start OAuth. Returns a browser registration link. This tool does not create an account, accept a password, or accept terms for the user.

为已有短链返回可扫描二维码。默认 PNG 512×512，并包含 image/png 图片块。仅当 format 为 svg 时返回 SVG，且不以 image 块返回。二维码中编码的是带有 ?s=qr 来源标记的短链接（使用 ASCII 域名），与 GET /v1/links/{id}/qr 返回的二维码内容一致。需要已注册账号，且必须是该链接的所有者。不新建短链，也不抓取目标地址。PNG 边长仅 256、512、1024，SVG 忽略边长。可能包含短期 image_url 及其到期时间；该链接不是 API 密钥、OAuth 令牌或会话。返回已存储短链的二维码：默认 PNG，请求时为 SVG；可用时附带短期 image_url。二维码编码的是 qr_tracking_url。未显示图片时，可使用 image_url（如有）或短链。 Return a scannable QR for an existing short link. Default PNG is 512×512 and includes an image/png image block. SVG is returned only when format is svg, and not as an image block. The matrix encodes the tracking URL with ?s=qr (ASCII host), the same payload as GET /v1/links/{id}/qr. A registered account that owns the link is required. Does not create a link and does not fetch the destination. PNG size is 256, 512, or 1024. SVG ignores size. A short-lived image_url and its expiry may be included. That URL is not an API key, an OAuth token, or a session. Returns the stored link's QR as PNG, or SVG when requested, with a short-lived image URL where available. The QR encodes qr_tracking_url. Where an image is not displayed, image_url (when present) or the short link reaches the same code.

查询本站短码或本站短链的已保存状态；仅 active 时返回目标地址。无需账号。不查询其他短链服务；查询结果不是安全检测结论。 Look up a 短.在线 code or short URL and return its saved state. The destination is returned only when active. No account required. Does not look up other shorteners. The result is not a security verdict.

为 HTTP 或 HTTPS 目标地址创建一条短链。需要已注册账号。返回链接状态；状态为 active 时，同时返回 Unicode 显示地址和 ASCII 地址。创建两条或更多短链时使用 shorten_urls。重试同一操作时，必须复用相同的 idempotency_key。 Create one HTTP or HTTPS short link. A registered account is required. Returns the state, and when active, the Unicode display URL and the ASCII URL. For two or more, use shorten_urls. A retry of the same operation must reuse the same idempotency_key.

一次同步创建 1 到 100 条短链。按 client_ref 对应结果，允许部分成功。需要已注册账号。批量重试只有三种情况，不要混用。示例：key 为 batch-1，两项 client_ref 分别为 notes（https://example.com/notes）和 draft（https://example.com/draft）。notes 成功，draft 的 retryable 为 true。(1) 传输结果不确定（没有拿到已完成的响应、IDEMPOTENCY_IN_PROGRESS、幂等锁不可用，或因瞬时数据库错误且一条都未创建而返回 503）：用同一个 key 原样重发整批。已完成的批次返回已保存的结果，notes 不会再次创建。key 已被释放时，同一批会重新执行。(2) 已完成且某项 retryable 为 true：重放 batch-1 只返回已保存的结果，不会重试 draft。只用新 key（例如 batch-1-draft）发送 draft，并保留 client_ref draft，不要带上 notes。去掉 notes 后仍用 batch-1 会返回 IDEMPOTENCY_CONFLICT。(3) 校验错误：改正请求，不要把同一份无效请求当作网络重试。key 尚未保存的 400（重复 client_ref、缺少 items、BATCH_TOO_LARGE）改正后可以继续用同一个 key。已完成且 retryable 为 false 的项已保存；修改请求体后继续使用原 key，会返回 IDEMPOTENCY_CONFLICT，改正后的项必须用新 key。 Create 1 to 100 short links in one synchronous request. Match each result by client_ref. Partial success is allowed. A registered account is required. Batch retry has three cases; do not mix them. Worked example: key batch-1 with client_ref notes (https://example.com/notes) and draft (https://example.com/draft). notes succeeds and draft is retryable true. (1) Uncertain transport outcome — no completed body, IDEMPOTENCY_IN_PROGRESS, an unavailable idempotency lock, or 503 because a transient database error created nothing: resend the entire unchanged batch with the same key. A completed batch returns the stored result and notes is not created again. A released key runs that same batch again. (2) Completed batch with retryable true: replaying batch-1 returns the stored body and does not retry draft. Send only draft, keeping client_ref draft, under a new key such as batch-1-draft. Do not include notes. Dropping notes and reusing batch-1 returns IDEMPOTENCY_CONFLICT. (3) Validation error: fix the request. Do not resend the same invalid body as a network retry. A 400 before the key is stored (duplicate client_ref, missing items, BATCH_TOO_LARGE) may reuse the key after the body is corrected. A completed item with retryable false is stored; a changed body on that key returns IDEMPOTENCY_CONFLICT, so send the corrected item with a new key.
