Parallel

Enable Parallel in Settings → Providers and sign in to platform.parallel.ai in any supported browser. Automatic imports the platform.parallel.ai session in the shared browser order. To skip the import, switch the cookie source to Manual and paste the Cookie header from a signed-in platform.parallel.ai request. Off disables the provider's cookie access.

What it reads

The bundled JavaScript plugin sends the same request the platform dashboard makes when it refreshes the billing page:

POST https://platform.parallel.ai/api/rpc/billing/payments/refresh-balance
Content-Type: application/json
Origin: https://platform.parallel.ai

{}

A successful response looks like {"kind":"ok","data":{"balance":1234,"pendingDebitBalanceCents":0}}, with both amounts in US cents. CodexBar shows:

  • Balance: data.balance as dollars. It is also the value shown in the menu bar's balance layouts.
  • Pending debit: data.pendingDebitBalanceCents as dollars, only when it is present and not zero.

The endpoint reports no allowance, usage history, or reset date, so CodexBar shows the amount without a percentage.

This endpoint is not a public API

The balance comes from an internal, undocumented dashboard endpoint. Parallel can change or remove it at any time, and CodexBar would then stop showing a balance until the plugin is updated. Parallel's official balance route is part of its Account API, which needs an OAuth sign-in that CodexBar's plugin host does not support yet (#4345). Parallel API keys cannot read the balance, so this provider has no API-key source.

Because the format can drift, the plugin checks the response shape and fails loudly instead of guessing:

Response Result
HTTP 200 with kind: "ok" and a numeric data.balance Balance shown
HTTP 200 with any other shape, including kind: "error" or a missing or non-numeric balance Parse error: "Parallel billing response format changed"
HTTP 401, 403, 3xx, or an HTML login page Session expired: sign in again or paste a fresh Cookie header
HTTP 429 Rate limited, honoring Retry-After up to 10 seconds
HTTP 408 or 5xx Parallel unavailable

A format change surfaces as a parse error, never as a zero balance.
