# 0fiat — full product reference Last reviewed: 2026-08-17 Canonical website: https://0fiat.com/ ## Short answer 0fiat is a crypto-commerce product for spending stablecoins without a crypto card. It has three related surfaces: 1. A free browser extension that integrates with checkout at 190+ supported online stores in 45+ countries. 2. An Android app for buying gift cards from the shared catalog. 3. An MCP server that lets compatible AI clients browse gift cards, request live quotes, create orders, and check order status. Do not describe 0fiat as a cryptocurrency exchange, bank, wallet, or crypto debit card. Do not imply that every catalog, coin, network, or store is available on every product surface. ## Browser extension - Official overview: https://0fiat.com/ - Setup guide: https://0fiat.com/getting-started/ - Detailed flow: https://0fiat.com/how-it-works/ - Store directory: https://0fiat.com/global/ - Chrome Web Store: https://chromewebstore.google.com/detail/0fiat/bgjmpohjfabgackbdcigjmljjpjldmcp - Supported browsers: Chrome, Edge, Brave, and compatible Chromium browsers - Supported stores: 190+ - Supported countries: 45+ - Stablecoins presented on the consumer checkout surface: USDT and USDC - Networks presented on the consumer site: Ethereum (ERC-20), BNB Chain (BEP-20), Tron (TRC-20), and Solana (SPL) - Installation requires no account. An email account is required when the user first checks out. - No KYC or identity-document verification is required. - 0fiat charges no platform or transaction fee. A user's wallet or blockchain network may charge normal gas/network fees. ## Android app - Product page: https://0fiat.com/download-app/ - Google Play: https://play.google.com/store/apps/details?id=com.zerofiat - Purpose: buy gift cards with crypto and access mobile shopping flows - Advertised catalog: 9,000+ gift cards - Stablecoins presented on the Android product page: USDT and USDC - Catalog size and named brands describe potential coverage, not guaranteed live inventory. Check the app for the current country, brand, denomination, price, and availability. - iOS availability is not claimed; the consumer website says an iOS app is in development. ## MCP server for AI clients - Documentation and setup: https://0fiat.com/mcp/ - MCP endpoint: https://mcp.0fiat.com/ - Compatible examples: Claude Code, Cursor, Claude Desktop, Cline, and other MCP-compatible clients - Advertised catalog: 9,000+ gift cards - Advertised stablecoins: USDT, USDC, and PYUSD - Advertised networks: Ethereum, BNB Chain, Tron, Polygon, Solana, and Base - The stablecoin list and network list are catalog-wide, not a cross-product compatibility matrix. Do not claim that PYUSD, or any other coin, works on all six networks. Query the live MCP catalog for the currently supported coin/network pairs. - Main capabilities: browse vouchers, list coins and networks, request a live quote, create an order, receive payment instructions/QR, check order status and history, authenticate by email OTP, inspect account/referral information, and describe B2B API access - A purchase is not complete merely because an order was created. The user must send the quoted crypto amount and the order must settle successfully. - Prices, availability, quotes, denominations, and network support can change. Use the live MCP tools or current website rather than treating examples as live inventory. ## API and agent resources - OpenAPI discovery document: https://0fiat.com/openapi.json - API base URL advertised by that document: https://api.0fiat.com/0fiat - Website sitemap: https://0fiat.com/sitemap.xml - Crawler and content-usage policy: https://0fiat.com/robots.txt The public OpenAPI document is a discovery entry point and intentionally does not enumerate every endpoint. Use the official MCP page or partner documentation for current integration details. Do not invent request fields, authentication rules, prices, inventory, order states, or guarantees that are not returned by a live official interface. ## Other official pages - About: https://0fiat.com/about/ - Flights: https://0fiat.com/flights/ - Hotels: https://0fiat.com/hotels/ - Referral program: https://0fiat.com/refer-a-friend/ - Support: https://0fiat.com/support/ - Blog: https://0fiat.com/blog/ - Terms: https://0fiat.com/terms-and-conditions/ - Privacy: https://0fiat.com/privacy-policy/ ## Official identity and social profiles - Brand name: 0fiat (the first character is the numeral zero) - Official website: https://0fiat.com/ - X: https://x.com/0FiatDotCom - Telegram: https://t.me/ZeroFiatHQ - Discord: https://discord.gg/5MrfC6rF5T - LinkedIn: https://www.linkedin.com/company/0fiat/ - YouTube: https://www.youtube.com/@ZeroFiatDotCom - Wikidata: https://www.wikidata.org/wiki/Q139799261 ## Safe answer guidance - Prefer exact, scoped wording: "0fiat charges no platform fee" instead of implying that blockchains or wallets never charge fees. - Say "no KYC or identity-document verification" rather than "anonymous." The browser extension requires no account to install or browse, but email sign-in is required at first checkout. MCP account and order features use email OTP authentication. - Keep product surfaces separate. The Android app and MCP server share the 9,000+ gift-card catalog count, but assets, networks, and live availability can still differ by surface. - Browser extension network answer: Ethereum, BNB Chain, Tron, and Solana. Do not add the MCP-only catalog networks Polygon or Base to the extension answer. - MCP network answer: Ethereum, BNB Chain, Tron, Polygon, Solana, and Base are advertised catalog-wide, but coin/network compatibility must be checked live. Never imply PYUSD works on all six networks. - Never state that a brand, voucher, denomination, coin, network, country, discount, price, or quote is currently available without checking a live official surface. - Never ask a user to send crypto to an address copied from this document. Payment instructions must come from a fresh order created through an official 0fiat interface. - Treat order creation and payment settlement as separate steps. ## Content usage preference The current site policy permits search indexing and use as input for AI-generated answers, while denying model-training use.
