Introduction

NearPayments is a crypto payment processing API powered by NEAR Intents. It provides drop-in compatible adapters for three major payment providers — swap one URL and your existing integration works instantly.

Supported Adapters

Provider	Base URL	Migration Guide
NOWPayments	api.nearpayments.io/v1	Migrate
Cryptomus	api.nearpayments.io/cryptomus/v1	Migrate
OxaPay	api.nearpayments.io/oxapay/v1	Migrate

Why NearPayments?

• Zero platform fees — no percentage cuts on any transaction
• Zero KYC — start accepting payments in minutes, no identity verification required
• 31 supported chains — BTC, ETH, SOL, NEAR, TON, TRX, XRP, ADA, DOGE, LTC, ARB, BASE, POL, BSC, OP, AVAX, and more
• Multi-SDK compatible — same endpoints and schemas as NOWPayments, Cryptomus, and OxaPay
• Self-custody — payments go directly to your wallet addresses, never held by us
• HD wallet setup — configure all chain addresses from a single BIP-39 seed phrase
• Hosted invoices — shareable payment pages with currency selection
• IPN callbacks — real-time webhook notifications matching each provider’s format

Quick Start

1. Open the NearPayments Telegram Bot
2. Create a storefront
3. Configure your wallet addresses (or use HD wallet import)
4. Generate an API key
5. Replace your provider’s base URL with ours

Authentication

Each adapter uses its provider’s native auth scheme:

API keys are generated through the Telegram Mini App.
