# Pricing

> How gateway calls are charged in pre.dev credits, and what the trial allows.

Gateway calls are paid with the same pre.dev credits as coding, planning, and browser tasks. **1 credit = \$0.10.**

## How a call is priced

Each call is charged in credits based on the model's metered cost for that call. The metered cost is reported in dollars as `usage.cost` on every inference response, and the credits charged are reported in the `x-predev-credits-charged` header.

The credit price per model is listed on [`GET /v1/models`](/ai-gateway/api/models): each row carries a `predev` object with `credits_per_m_input` and `credits_per_m_output`, and, where the model has them, `credits_per_m_cache_read`, `credits_per_m_cache_write`, `credits_per_image`, and `credits_per_request`. Read those numbers rather than deriving prices yourself; they are what the charge is computed from.

Worked example: a model whose row lists `credits_per_m_input: 28.6` and `credits_per_m_output: 142.9` costs 0.286 credits for 10,000 input tokens plus 0.286 credits for 2,000 output tokens, so a call of that size settles at about 0.57 credits.

## What is included

* Plugin costs, such as web search, are part of `usage.cost` and therefore of the charge.
* With `models` fallbacks or `provider` preferences, you pay the price of the model and provider that actually served the call.
* Streams settle at the final chunk. If your client disconnects mid-stream, the call is still charged for what the model generated.
* Video jobs are charged when a status poll reports completion. See [images and video](/ai-gateway/api/images-and-video).
* Catalog reads (`/v1/models`, `/v1/providers`, and the per-modality model lists) are free and not rate-limited.

Each inference response reports the charge in `x-predev-credits-charged` and the balance in `x-predev-credits-remaining`. [`GET /v1/usage`](/ai-gateway/api/usage) breaks the last 1–90 days down by model and path.

## Trial

A free workspace can make **5 credits** of gateway calls in total. After that, every call returns `402` with code `subscription_required` until the workspace subscribes. Trial workspaces are also limited to 30 requests per minute.

## Out of credits

A workspace with no credits gets `402` with code `insufficient_credits` before anything is sent to the model, so nothing is generated and nothing is charged. The error body includes `credits_remaining`, `estimated_credits`, and a `topup_url`. See [errors](/ai-gateway/api/errors).

Turn on auto-recharge in dashboard billing to keep a deployed app running when the balance would otherwise reach zero.

## Rate limit

Requests are limited per workspace per minute: 600 by default, 30 on trial. A `429` carries a `Retry-After` header. Catalog reads do not count.

See [plans and credits](/coding-agent/plans-and-credits) for plan allowances.
