Billing & Usage

How Chaser charges, how to check your balance, and how to add funds.

Pricing

$5 per gigabyte of egress.

• 1 GB = 1,000,000,000 bytes
• Egress = bytes_up + bytes_down (all TCP bytes through the session’s proxy)
• Residential proxy is included — no separate proxy fee
• No per-session charge, no idle charge, no minimum

Free credit

Every workspace starts with 100 MB of free credit. It never expires. You can use it to test the full API before adding funds.

Checking usage

$
curl -s https://api.chaser.sh/v1/usage \
>
  -H "Authorization: Bearer $CHASER_KEY" | jq '.totals'

billed_micro_usd is the total charge in micro-dollars. Divide by 1,000,000 for dollars: $1.73.

Adding funds

Top up through the dashboard’s billing page, or via the API:

$
curl -s https://api.chaser.sh/v1/billing/topup \
>
  -X POST \
>
  -H "Cookie: chaser_session=..." \
>
  -H "Content-Type: application/json" \
>
  -d '{"amount_usd": 50}'

This returns a Stripe checkout URL. Complete payment there. Funds are credited to the workspace balance immediately after Stripe confirms payment.

• Minimum top-up: $10
• Credits never expire
• No auto-top-up — you control when and how much to add

Insufficient balance

If the workspace balance reaches zero:

• Active sessions continue until they expire or are deleted
• New session creation returns 402 payment_required
• Top up to resume

Cost estimation

Actual egress depends on page weight, images, scripts, and API calls the page makes. The numbers above are typical for text-heavy pages with moderate assets.

Invoicing

Chaser is prepaid — you add funds, then spend them. There are no post-paid invoices. Stripe sends a receipt for each top-up.
