Subscription plans

1. Create an invoice

2. Track payment, then activate

Transfer STX only once, using the exact recipient, amount, memo and payer address from your invoice. A pending or unavailable status is not permission to send again.

Checking status is read-only. Activating may issue your API key, but never transfers STX. Keep your order secret and TXID: they let you retry after a temporary outage without paying again.

3. My combined API allowance

One key can access all linked active purchases, including mixed Starter, Pro and Developer plans. Each purchase keeps its own 30-day expiry; expired allowances are not included. Usage is counted per authenticated attempt.

Read-only lookup. It does not use your paid API attempts. The totals count active orders only; the current status endpoint does not expose each purchase's individual expiration date.

4. Combine existing paid purchases

Already bought plans separately? Keep your preferred key and add another active purchase to it. Both keys must belong to the same paying Stacks address.

This updates which purchase your preferred key can use. It does not send STX, change either purchase's expiry, reset usage or duplicate quota. The other key is not automatically revoked. Only submit once; if a network error occurs, check combined allowance before attempting again.
