Summary: Cryptorefills is a crypto-spending catalog with a real checkout API and newer agent-facing distribution. The reusable surface is catalog search, quote, order, payment, and delivery orchestration — not the gift cards themselves.
What it does:
Lets users buy gift cards, mobile top-ups, eSIMs, flights, and stays with Bitcoin, Lightning, stablecoins, and other crypto assets across many countries
Exposes a partner REST API for catalog browsing, product pricing, order validation, order creation, and order-status tracking via SSE or polling
Publishes MCP discovery artifacts, agent skills, and an HTTP MCP endpoint so AI agents can browse products and complete purchases through a structured tool layer
Supports autonomous x402-based purchasing for AI agents using USDC on Base without the traditional API-key or OAuth setup described on the site
Maintains supplier/brand partnership paths that include direct API integration for proven cases or stocked-code supply relationships
Positions itself as a real-world spending rail for wallet apps, rewards programs, mini apps, treasury-spend helpers, and other Web3 or agentic commerce flows
Key claims:
The homepage says users can choose from 6,600+ gift cards, eSIMs, flights, stays, and mobile top-ups, pay with BTC, ETH, USDT, USDC, and many more, and receive products instantly; it also explicitly says the platform is built for AI agents via skills, MCP, and x402
The API landing page describes Cryptorefills as “the stablecoin checkout API for gift cards, mobile top-ups and eSIMs,” says builders can move from search to quote to payment to delivery in one deterministic flow, and says inventory can be issued at checkout time instead of pre-buying stock
The developer API reference documents a partner-authenticated REST surface with headers such as X-Cr-Application, X-Cr-Version, and X-Country-ISO-Code, plus endpoints for payment methods, country brand catalogs, product browsing, price conversion, validation, order creation, and order tracking
The developer docs recommend validating before order creation, note a 30-minute payment window, and expose both SSE subscription flow and polling fallback for order-state tracking, which is a strong signal of an operational commerce platform rather than a thin checkout wrapper
The AI-agents page says Cryptorefills is the first platform where AI agents can autonomously search, quote, and purchase gift cards and mobile top-ups using stablecoins, and it documents three published skills: cryptorefills-catalog, cryptorefills-buy, and cryptorefills-x402
The AI-agents page and llms.txt publish machine-readable discovery surfaces including an MCP manifest, API catalog, agent-skills index, HTTP/SSE MCP transports, and public agent-skill documents, which is unusually explicit agent-integration posture for a crypto spending platform
The public llms.txt says MCP and x402 flows work without account, OAuth, or API-key provisioning, while the partner developer API uses partner headers; together these surfaces suggest Cryptorefills is operating two access models at once: a conventional partner API and a lower-friction agent-native purchase layer
The supplier partnership page says Cryptorefills reaches users directly and through partners such as Binance, accepts Lightning and major cryptocurrencies, and can onboard supply either through direct brand API integration or through stocked-code relationships
The official materials are inconsistent on catalog scale: the homepage and API marketing pages say 6,600+ brands/products, while llms.txt, the AI-agents page, and the public GitHub agents repo say 10,500+ brands. That discrepancy is worth noting, but it does not change the broader conclusion that the company is packaging programmable crypto-spending infrastructure
Whitepaper: No canonical standalone Cryptorefills whitepaper or litepaper surfaced in this pass. The clearest current sources of truth were the official site, partner API docs, AI-agent pages, machine-readable discovery files, supplier-partnership page, and first-party GitHub agent-skills repo; see ../whitepapers/cryptorefills-primary-sources-2026-05-02.md.
