search-for-service
Search and browse the x402 bazaar marketplace for paid API services. Use when you or the user want to find available services, see what's available, discover APIs, or need an external service to accomplish a task. Also use as a fallback when no other skill clearly matches — search the bazaar to see if a paid service exists. Covers "what can I do?", "find me an API for...", "what services are available?", "search for...", "browse the bazaar".
About this skill
The `search-for-service` skill enables an AI agent to interact with the x402 bazaar, a marketplace for paid API endpoints. It provides commands to search for services by keyword, list all available resources, and inspect the payment requirements of specific endpoints. This is crucial for agents needing to extend their capabilities beyond their inherent functions or other installed skills. Agents can use this skill to dynamically find and evaluate external APIs, understand what services are available, and identify potential tools to solve complex problems or fulfill user requests. It acts as a discovery mechanism, allowing the agent to explore a wide range of external services without requiring prior knowledge or authentication for the search process. Key use cases include responding to user queries like "what can I do?", "find me an API for X", or "browse the bazaar". It also serves as a robust fallback mechanism: if no other skill directly addresses a user's need, the agent can search the x402 bazaar to see if a paid service exists that could achieve the goal, thus increasing the agent's problem-solving versatility.
Best use case
The primary use case is for AI agents that need to dynamically discover and potentially integrate external API services to complete a user's request or solve a task that is outside their immediate capabilities. Developers and power users who leverage AI agents for complex problem-solving or automation will benefit most, as it expands the range of solutions the agent can propose and implement.

A list of relevant API services or detailed information about a specific service from the x402 bazaar, potentially including their descriptions and payment requirements.
Practical example
Example input
Find a paid API service on the x402 bazaar that can convert text to speech.
Example output
Searching x402 bazaar for 'text to speech'... Results: 1. 'TextToSpeechPro' - Converts text to high-quality audio. (Details: npx awal@latest x402 details TextToSpeechPro) 2. 'VoiceSynth API' - Generates natural-sounding speech from input text. (Details: npx awal@latest x402 details VoiceSynthAPI)
When to use this skill
- When a user asks for an API or service to perform a specific task.
- When no other installed skill can clearly fulfill a user's request.
- To explore and understand the range of paid API services available on the x402 marketplace.
- To discover external services required to accomplish a complex task.
When not to use this skill
- When the task can be fully completed using the agent's internal capabilities or existing integrated skills.
- When the user explicitly states they do not wish to use external or paid services.
- When the exact required API is already known and directly accessible.
- For tasks that do not involve discovering or interacting with external API services.

# Searching the x402 Bazaar Use the `npx agnic@latest 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 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 (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 ```bash # Search for weather-related paid APIs npx agnic@latest x402 bazaar search "weather" # Search with more results npx agnic@latest x402 bazaar search "sentiment analysis" -k 10 # Browse all bazaar resources with full details npx agnic@latest x402 bazaar list --full # 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 ## Next Steps Once you've found a service you want to use, use the `pay-for-service` skill to make a paid request to the endpoint. ## 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
