Agnic Search for Service

Search the x402 bazaar for paid API services. Use when the user wants to find APIs, discover services, browse the marketplace, or needs an external service. Also use as a fallback when no other skill matches. Covers "find me an API", "what services are available", "search for", "browse bazaar", "what can I do".

Searching the x402 Bazaar

Use npx agnic@latest x402 commands to discover and inspect paid API endpoints on the x402 bazaar marketplace. No authentication or balance is required for searching.

Commands

Search the Bazaar

Find paid services by keyword using BM25 relevance search:

bash

npx agnic@latest x402 bazaar search <query> [-k <n>] [--force-refresh] [--json]

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:

bash

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

Option	Description
--network <name>	Filter by network (base, base-sepolia)
--full	Show complete details including schemas
--json	Output as JSON

Discover Payment Requirements

Inspect an endpoint's x402 payment requirements without paying:

bash

npx agnic@latest x402 details <url> [--json]

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

Examples

bash

# Search for weather-related paid APIs
npx agnic@latest x402 bazaar search "weather" --json

# Search with more results
npx agnic@latest x402 bazaar search "sentiment analysis" -k 10 --json

# Browse all bazaar resources
npx agnic@latest x402 bazaar list --full --json

# Check what an endpoint costs
npx agnic@latest x402 details https://example.com/api/weather

Prerequisites

• No authentication needed for search, list, or details commands

Error Handling

Common errors:

• "CDP API returned 429" -- Rate limited; cached data will be used if available
• "No X402 payment requirements found" -- URL may not be an x402 endpoint
• No results -- Try broadening the search query or using different keywords
