This document provides the API reference and integration guide for the CoinPool platform (v1.1), designed to empower engineers, merchants, liquidity providers, and enterprises to build seamless fiat-to-crypto and crypto-to-fiat experiences.

​
Purpose and Overview

CoinPool is a secure, compliant hybrid bridge between traditional fiat currencies and USDT stablecoin on Ethereum (ERC-20) and TRON (TRC-20) networks. Our APIs enable:
  • P2P On/Off-Ramps — Allowing individual users and small businesses to convert fiat to USDT and USDT to fiat quickly and affordably, with support for mobile-first flows optimized for African corridors.
  • B2B OTC Desk — Facilitating large-scale, private USDT/fiat trades for enterprises, merchants, and liquidity providers with minimal slippage, tailored execution, and high-volume capabilities.
  • B2B Merchant and Vendor Integrations — Enabling E-Commerce platforms, sub-merchants, and partners to accept USDT payments, request OTC conversions, manage custodial/non-custodial wallets, and automate settlements.
The APIs serve as the programmatic foundation for these use cases, providing endpoints for:
  • Merchant onboarding and KYC/KYB verification
  • Fiat deposit requests (bank/M-Pesa) and status tracking
  • USDT credit/debit operations across networks
  • Wallet balance queries and transaction history
  • Real-time rate quotes and OTC order management
  • Webhooks for asynchronous updates (e.g., payment confirmations, credits)
This documentation serves as the single source of truth for engineers integrating with CoinPool. It defines authentication methods, request/response formats, error handling, rate limits, sandbox testing guidelines, and best practices to ensure secure, reliable, and scalable implementations.

​
Who This Is For

  • Merchants and E-commerce Platforms — Integrate USDT acceptance or fiat-to-USDT conversion into checkout flows.
  • OTC Traders and Liquidity Providers — Automate large-volume trades, monitor queues, and manage treasury operations programmatically.
  • Individual Developers and P2P Builders — Build custom on/off-ramp experiences or wallets connected to CoinPool’s rails.
  • Enterprises and Fintech Partners — Leverage CoinPool for cross-border settlements, treasury hedging, and compliant stablecoin access in Africa-EU/UAE corridors.
By integrating with CoinPool APIs, you gain access to low-fee, fast-settling stablecoin infrastructure backed by robust compliance (VASP-aligned), real-time monitoring, and future-proof design for additional chains, tokens, and fiat corridors.
