Commands

Search the Bazaar

Find paid services by keyword using BM25 relevance search:

Option	Description
-k, --top <n>	Number of results (default: 5)
--force-refresh	Re-fetch resource index from CDP API
--json	Output as JSON

Results are cached locally at ~/.config/agnic/bazaar/ and auto-refresh after 12 hours.

List Bazaar Resources

Browse all available resources:

npx agnic@latest x402 bazaar list [--network <network>] [--full] [--json]

Option	Description
--network <name>	Filter by network (base, base-sepolia)

--json	Output as JSON

Discover Payment Requirements

Inspect an endpoint's x402 payment requirements without paying:

npx agnic@latest 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.

Error Handling

Common errors:

• "No X402 payment requirements found" — URL may not be an x402 endpoint
• No results — Try broadening the search query or using different keywords
