SDKs & CLI - Grid API Documentation

Grid provides official SDKs to help you integrate faster. These libraries wrap the Grid API with idiomatic interfaces, type safety, and built-in error handling.

JavaScript / TypeScript

Install via npm and start building with full TypeScript support.

Kotlin

For JVM and Android applications. Available on Maven Central.

CLI

The Grid CLI lets you interact with the Grid API directly from your terminal — manage customers, send payments, create quotes, and test in sandbox without writing any code.

Grid CLI

Open-source CLI built with Node.js and TypeScript.

Installation

Prerequisites: Node.js v20 or v22 is required.

git clone https://github.com/lightsparkdev/grid-api.git
cd grid-api/cli
npm install
npm run build
npm link        # makes `grid` available globally

Configuration

Configure your credentials interactively:

grid configure

This prompts for your API Token ID and Client Secret, validates them, and saves to ~/.grid-credentials. Alternatively, set environment variables:

export GRID_API_TOKEN_ID="your-token-id"
export GRID_API_CLIENT_SECRET="your-client-secret"

Commands

Command	Description
`grid configure`	Set up API credentials
`grid config get`	View platform configuration
`grid customers list`	List customers
`grid customers create`	Create a customer
`grid accounts internal list`	List internal accounts
`grid accounts external create`	Create an external bank account or wallet
`grid quotes create`	Create a payment quote
`grid quotes execute`	Execute a pending quote
`grid transfers in`	Transfer funds in (external to internal)
`grid transfers out`	Transfer funds out (internal to external)
`grid transactions list`	List transactions
`grid transactions get`	Get transaction details
`grid receiver lookup-uma`	Look up a UMA address
`grid sandbox fund`	Fund a sandbox account
`grid sandbox send`	Simulate sending funds to a JIT quote
`grid sandbox receive`	Simulate receiving a UMA payment

Short aliases are available: cust for customers, tx for transactions, acct for accounts.

Example: Send USDC to a Mexico Bank Account

Create a customer

grid customers create \
  --platform-id "your-id" \
  --type INDIVIDUAL \
  --full-name "Carlos Garcia" \
  --birth-date "1988-03-20" \
  --address-line1 "Av Reforma 222" \
  --address-city "Mexico City" \
  --address-state "CDMX" \
  --address-postal "06600" \
  --address-country "MX"

Create an external CLABE account for the customer

grid accounts external create \
  --customer-id <customerId> \
  --currency MXN \
  --account-type CLABE \
  --clabe "012345678901234567" \
  --beneficiary-type INDIVIDUAL \
  --beneficiary-name "Carlos Garcia" \
  --beneficiary-birth-date "1988-03-20" \
  --beneficiary-nationality MX

Create a quote

grid quotes create \
  --source-customer <customerId> \
  --source-currency USDC \
  --dest-account <externalAccountId> \
  --dest-currency MXN \
  --amount 100000 \
  --lock-side RECEIVING

In sandbox, simulate the USDC deposit

grid sandbox send --quote-id <quoteId> --currency USDC

Check transaction status

grid transactions get <transactionId>

All amounts are in the smallest currency unit (e.g., cents for USD, satoshis for BTC). Quotes expire in 1–5 minutes.
