Cryptorefills Catalog — Browse & Search

Read-only product discovery. Use this skill when users want to explore, search, compare, or learn about products available on Cryptorefills.

For purchasing, follow the instructions in:

• cryptorefills-buy — guided MCP purchase workflow with all crypto payment methods
• cryptorefills-x402 — autonomous agent commerce with USDC on Base (no account needed)

When the user's intent shifts from browsing to buying, stop using this skill's tools and switch to the instructions in the appropriate purchase skill above.

When to Activate

• User mentions Cryptorefills or wants to know what's available in a country
• User asks about pricing, availability, supported countries, or payment currencies
• User wants catalog information in a specific language
• Keywords: "find gift card", "what brands", "esim for travel", "top up phone", "available in [country]", "buy with bitcoin", "buy with ethereum", "buy with solana", "crypto gift card"

Available Tools

Quick Decision Tree

User intent
├─ "Find me a specific brand" → searchProducts(country_code=XX, q=brand)
├─ "What's available in [country]?" → listBrands(country_code=XX)
├─ "Show me all [category] options" → listProductsForCountry(country_code=XX, family=...)
├─ "What crypto can I pay with?" → getCurrencies() or getPaymentViasWithCurrencies()
└─ "I want to buy"
   ├─ Agent has USDC wallet on Base + can sign EIP-712 → cryptorefills-x402
   └─ Otherwise (human-guided, multi-currency) → cryptorefills-buy

Task Flows

Search by Brand

1. Ask user for brand name and country
2. Call searchProducts with country_code (uppercase: US, IT, BR) and q (search text)
3. Present matching products with denominations and prices
4. If user wants to buy → switch to cryptorefills-buy instructions

Browse by Country

1. Ask user for country (or detect from context)
2. Call listBrands with country_code
3. Present brands grouped by category (e.g., e-commerce, games, streaming)
4. User selects a brand → call listProductsForCountry for details

Explore Categories

1. Call listBrands for the user's country
2. Group results by category field — categories are discovered dynamically from the response, not hardcoded
3. Present categories with brand counts
4. Drill into a category by filtering results

Check Payment Options

1. Call getCurrencies to show supported coins
2. Call getPaymentViasWithCurrencies for network details
3. Present payment methods with chain/asset info

Multi-Language

Pass lang parameter to tools. Supported: en, es, fr, de, it, pt, zh, tr, vi, tl. Falls back to English if unavailable.

Brand Name Matching

Brand names in API responses may include suffixes (e.g., "Claro Credits" not "Claro", "Vivo Credits" not "Vivo", "Everything Apple" not "Apple"). Always use the exact brand value from listBrands — partial matches will fail.

Tips

• Country codes — Use uppercase ISO 3166-1 Alpha-2 (e.g., US, IT, BR). Note: the x402 skill uses lowercase — different endpoints, different format
• Country must match product region — A US gift card only works in the US
• Phone numbers — Mobile top-ups require E.164 format (+1234567890)
• Range products — Check is_dynamic flag and min/max values before suggesting amounts
• Promotions — listBrands supports promotional code and customer ID parameters

Limitations

This skill is read-only. It cannot create orders or process payments.

• To buy products → switch to cryptorefills-buy (all payment methods, guided flow)
• For autonomous agent purchases → switch to cryptorefills-x402 (USDC on Base, no account)
