PayTrigo (OpenClawBot, Base/USDC)

This skill provides a minimal, bot-friendly payment flow on PayTrigo using a platform API key and Base/USDC only. It is optimized for OpenClawBots that do not run webhooks and instead poll for status. A platform key is embedded in the helper script for no-setup usage.

Assumptions

• Platform key is used (recipientAddress required).
• Base/USDC is the only enabled chain/token for this key (from Platform Fee Configs).
• Bots can store invoiceId and checkoutToken returned from invoice creation.

No environment variables required

The helper script ships with an embedded key, so OpenClawBots can use it immediately.

Install

Requires Node.js 18+.

npm install

Local wallet memory (recommended)

OpenClawBots can store a recipient address and an encrypted payer wallet locally (no external services needed).

1) Create a local wallet store

node {baseDir}/scripts/moltbot-wallet-setup.mjs create --passphrase-file ./passphrase.txt --set-recipient-from-wallet

This creates .openclawbot/wallet.json, .openclawbot/wallet-address.txt, and .openclawbot/recipient.txt.

If you already have a wallet

You do not need to create a new one.

node {baseDir}/scripts/moltbot-wallet-setup.mjs recipient --address 0xYourWallet
node {baseDir}/scripts/moltbot-wallet-setup.mjs import --pk-file ./payer.pk --passphrase-file ./passphrase.txt --set-recipient-from-wallet

2) Run flows using the stored data

node {baseDir}/scripts/moltbot-human-flow.mjs human --amount 0.001
node {baseDir}/scripts/moltbot-bot-flow.mjs bot --amount 0.001 --passphrase-file ./passphrase.txt

3) Optional: set a separate recipient address

node {baseDir}/scripts/moltbot-wallet-setup.mjs recipient --address 0xYourWallet

Quickstart (CLI scripts)

Use the scenario scripts to test end-to-end flows without additional setup.

Human-in-the-loop (user pays in browser)

node {baseDir}/scripts/moltbot-human-flow.mjs human --amount 0.001 --recipient 0xYourWallet...

Bot pays directly (requires private key)

node {baseDir}/scripts/moltbot-bot-flow.mjs bot --amount 0.001 --recipient 0xYourWallet... --pk 0xPRIVATE_KEY

See README.md in this folder for a short OpenClawBot-focused guide.

Core flow (Human-in-the-loop)

1) Create invoice (platform key, Base/USDC, recipientAddress required)

2) Send payUrl to the user (approval + payment)

3) Poll invoice status until confirmed | expired | invalid | refunded

Core flow (Bot pays directly)

1) Create invoice

2) Get intent (approve/pay calldata)

3) Send on-chain tx (approve if needed, then pay)

4) Submit txHash

5) Poll status

> Important: Direct token transfer is invalid. Always use the Router steps.pay from /intent.

API Usage (HTTP)

1) Create invoice

Endpoint: POST /v1/invoices

Headers:

• Authorization: Bearer (required if calling HTTP directly)
• Content-Type: application/json
• Idempotency-Key: pay_attempt_

Body (Base/USDC fixed, recipientAddress required)

{
  "amount": "49.99",
  "recipientAddress": "0xYourWallet...",
  "ttlSeconds": 900,
  "metadata": { "botId": "openclawbot_123", "purpose": "checkout" }
}

Response includes invoiceId, payUrl, checkoutToken, expiresAt.

2) Get intent (bot-pay)

Endpoint: GET /v1/invoices/{invoiceId}/intent?chain=base&token=usdc

Headers (preferred):

• X-Checkout-Token:

Response includes steps.approve, steps.pay, routerAddress, grossAmountAtomic.

3) Submit payment intent (txHash)

Endpoint: POST /v1/invoices/{invoiceId}/payment-intents

Headers:

• X-Checkout-Token:
• Content-Type: application/json

Body

{ "txHash": "0x...", "payerAddress": "0x..." }

4) Poll invoice status

Endpoint: GET /v1/invoices/{invoiceId}

Headers:

• X-Checkout-Token:

Stop when: status is confirmed | expired | invalid | refunded.

Polling policy (safe default)

• submitted right after tx: poll every 3-5s for 2 minutes
• After 2 minutes: poll every 10-15s
• Stop at expiresAt + grace (status will not change after that)
• If you receive 429, backoff and retry later

Common mistakes

• Missing recipientAddress with platform key (invalid)
• Direct token transfer instead of Router pay
• Losing checkoutToken (it is only returned on invoice creation)
