\`Goal: Read the organization's current pre-paid credit balance (USD) plus its auto-refill configuration.

Endpoint: GET https://verification.didit.me/v3/billing/balance/
Auth header: x-api-key: <DIDIT_API_KEY>

curl:
curl -X GET 'https://verification.didit.me/v3/billing/balance/' \
-H 'x-api-key: YOUR_API_KEY'

Response 200:
\{
"balance": "1234.5600",                  // USD, FIXED-POINT DECIMAL STRING — parse with Decimal/BigDecimal, not float.
"auto_refill_enabled": true,             // boolean
"auto_refill_amount": "500.00",          // USD string or null
"auto_refill_threshold": "100.00"        // USD string or null — auto-refill fires when balance falls below this
}

Notes:
\- Balance is ORGANIZATION-WIDE — shared across every application under the same org.
\- Decreases as verifications are billed; increases when a top-up settles via Stripe webhook.
\- Currency is always USD.
\- Configure auto-refill in Console → Billing; requires a saved Stripe payment method (card, SEPA, or US ACH). The auto-refill amount is $50 to $20,000, added at face value, the same range as a manual top-up.
\- Poll at a low cadence (every few minutes max) — balance only changes when usage is billed or a top-up settles.

Common patterns:
\- Gate session creation in production — stop opening new sessions if balance drops below your operational floor.
\- Power internal dashboards / low-balance alerts.
\- Detect misconfigured auto-refill: auto_refill_enabled=true with null auto_refill_amount/threshold means it's effectively off (or no eligible payment method on file).

Failure modes (envelope {"detail": "..."}):
\- 401 — missing/malformed x-api-key.
\- 403 — key valid but bound application not allowed to read billing.
\- 429 — rate-limited.

See /getting-started/pricing for the credit consumption model and POST /v3/billing/top-up/ to add funds programmatically.

For end-to-end Didit integration, paste in the full prompt at /integration/integration-prompt.`

        密钥”中获取。主密钥拥有完整访问权限。指定名称的密钥可设置作用域：针对每个资源设为无权限、只读或读写，限定于特定工作流或已通过的会话、限定于
        IP 地址列表，以及设置到期日期。401 表示密钥错误、已撤销或已过期；403 表示未发送密钥、密钥无权访问该资源或操作，或请求来自其 IP
        列表之外的地址；在会话路由上返回 404 表示该会话不在该密钥允许的工作流或状态范围内。没有媒体访问权限的密钥获取到的图片、视频和 PDF
