Credits
Buy a prepaid balance by card and give your agent an API key. Same prices as paying per call in USDC, debited only when a call succeeds. After paying you land in your account: balance, activity, key.
New here? Buy credits
Choose an amount in USD (min $5, max $1000). You will be sent to Stripe Checkout and back into your new account; your card is charged in your local currency at today's rate.
Your API key is created with the account and shown in your dashboard after payment; you can regenerate it there any time.
Already have a key? Sign in
Your key is the password to your balance: it opens the dashboard (balance, activity, top-ups, key rotation). Sessions last 30 days on this browser.
Lost your key?
A one-time link (valid 15 minutes) opens your dashboard so you can generate a new key. Works for every account linked to that email.
In your agent
x-toll402-key: tk_… # any HTTP call
TOLL402_API_KEY=tk_… # toll402-mcpAgents can read the same data as the dashboard: GET /v1/account with the key.
Why credits
No crypto needed
A card and two minutes. The agent never sees a wallet; it only holds a key you can rotate.
Same prices, same tools
The catalog price is the price. Provider endpoints, the directory, forged tools: all of it.
Only successful calls are charged
A 4xx or 5xx never touches the balance. Every debit is in your activity log. Credits are non-refundable.
