Searching the x402 Bazaar

Use the npx [email protected] x402 commands to discover and inspect paid API endpoints available on the x402 bazaar marketplace. No authentication or balance is required for searching.

Commands

Search the Bazaar

Find paid services by keyword using CDP's vector search:

npx [email protected] x402 bazaar search <query> [-k <n>] [--network <network>] [--scheme <scheme>] [--max-price <price>] [--json]

Option	Description
-k, --top <n>	Number of results, 1–20 (default: 20)
--network <name>	Filter by chain (base, base-sepolia, polygon, solana, solana-devnet)
--scheme <scheme>	Filter by payment scheme: exact or upto
--max-price <price>	Maximum price in USD (e.g. 0.01)
--asset <address>	Filter by payment asset address
--pay-to <address>	Filter by recipient wallet address
--extensions <type>	Filter by extension type (e.g. outputSchema, bazaar)
--json	Output as JSON

List Bazaar Resources

Browse all available resources:

npx [email protected] x402 bazaar list [--network <network>] [--full] [--refresh] [--json]

Option	Description
--network <name>	Filter by chain (base, base-sepolia, polygon, solana, solana-devnet)
--full	Show complete details including schemas
--refresh	Re-fetch resource index from CDP API
--json	Output as JSON

Discover Payment Requirements

Inspect an endpoint's x402 payment requirements without paying:

npx [email protected] x402 details <url> [--json]

Auto-detects the correct HTTP method (GET, POST, PUT, DELETE, PATCH) by trying each until it gets a 402 response, then displays price, accepted payment schemes, network, and input/output schemas.

Examples

# Search for weather-related paid APIs
npx [email protected] x402 bazaar search "weather"

# Search with more results
npx [email protected] x402 bazaar search "sentiment analysis" -k 10

# Browse all bazaar resources with full details
npx [email protected] x402 bazaar list --full

# Check what an endpoint costs
npx [email protected] x402 details https://example.com/api/weather
