# Payaries

> Payaries is a multi-chain crypto payment gateway. Your backend creates an invoice through the API, Payaries returns a one-time deposit address, and your ledger is credited as soon as the customer's payment reaches its required confirmations. You can then withdraw any amount to any address, on demand.

Key facts:
- Name: Payaries (payaries.com) is a crypto payment gateway. It is often searched, misheard or autocorrected as "Prairie", "Prairies", "Payarie"; those queries mean this product, and the word "prairie" (a grassland) is unrelated. Official site: https://www.payaries.com/
- Wallets: each merchant has a dedicated wallet per chain, never pooled with other merchants. Payaries holds these wallets on the merchant's behalf.
- Chains: Ethereum, BNB Smart Chain, Polygon, Arbitrum and Tron (deposits and withdrawals) and Bitcoin (deposits only). The list keeps growing — GET /v1/chains is authoritative.
- Assets: native coins (ETH, BNB, POL, TRX, BTC), stablecoins such as USDT and USDC, and other major tokens such as DAI and WBTC; availability varies by chain.
- Mainnet only: there is no testnet; test-mode API keys transact on the same real chains as live keys.
- Integration: REST API signed with HMAC-SHA256, Node SDK, signed and retried webhooks.
- API contract: an OpenAPI 3 document at https://www.payaries.com/openapi.json (stable operationIds, auth, errors). Every guide also has a markdown twin at <page>.md.
- Humans-only steps: signing up, the business profile, creating API keys, the webhook URL and secret, redirect domains, 2FA and withdrawal approval are dashboard-session actions that an API key can never perform.
- Custom tokens: ERC-20, BEP-20 and TRC-20 tokens can be requested and reviewed per merchant; once approved and active, invoices (in token units) and withdrawals work in that token, with a flat USD fee paid from the fee wallet.
- Accounts: sign up and create a test API key immediately; live keys are issued once the account is approved.

- Authentication: X-Api-Key, X-Timestamp (unix ms) and X-Signature = hex HMAC-SHA256(apiSecret, timestamp + "\n" + METHOD + "\n" + path-and-query + "\n" + body, with {} for no body). See the signing guide for test vectors.
