faq:
  - q: How do I add stablecoin payments to a Replit app?
    a: Tell Replit Agent to integrate the BlindPay API using the prompt below, then add BLINDPAY_API_KEY and BLINDPAY_INSTANCE_ID in Replit Secrets. The agent scaffolds a backend route that calls BlindPay for quotes and payouts.
  - q: Does Replit Agent support the BlindPay API?
    a: Yes. Replit Agent can call any REST API. Give it the BlindPay prompt and credentials, and it generates the backend route plus UI for stablecoin payouts and on-ramps.
  - q: Where do I put my BlindPay API key in Replit?
    a: Use Replit Secrets (the lock icon / Tools → Secrets). Add BLINDPAY_API_KEY and BLINDPAY_INSTANCE_ID, then read them from the environment in your server code. Never hardcode the key.

[Replit](https://replit.com){target="_blank"} and Replit Agent build and host full-stack apps. This guide adds **stablecoin payments**: payouts, on-ramps, and virtual accounts: with the BlindPay REST API and Replit Secrets.

## Copy-paste prompt

Give this to Replit Agent:

```text [Replit Agent prompt]
Integrate stablecoin payments using the BlindPay API (https://api.blindpay.com).

- Add a backend route that creates a payout quote and executes a payout:
  POST /v1/instances/${BLINDPAY_INSTANCE_ID}/payouts/evm/quote and /payouts/evm.
- Authenticate with Authorization: Bearer ${BLINDPAY_API_KEY}.
- Read BLINDPAY_API_KEY and BLINDPAY_INSTANCE_ID from Replit Secrets (environment).
- Build a UI: enter a USDC amount and destination, show the live quote, send the payout.
- Keep the secret key server-side only.
