## Packages

## Tools (8)

- `check_endpoint_health`: Probe and verify the reachability, HTTP status code, latency, and operational health of an AI API endpoint or web service. Follows redirects with a 15-second timeout. Requires x402 micropayment (0.01 USDC on Base).

When to use: Check if a specific API URL or model endpoint is online, responding, or returning 5xx/402 errors.
When NOT to use: Do NOT use for general domain WHOIS or DNS record lookups.

Parameters:
- `url` (string, required): Target HTTP/HTTPS endpoint URL to probe (8-1000 chars), e.g. 'https://api.openai.com/v1/models'.
- `extract_json_from_web`: Extract structured JSON data matching a custom schema directly from any webpage. Extracts clean content and processes schema mapping via fast LLM parsing. Requires x402 micropayment (0.015 USDC on Base).

When to use: Scraping structured data (product specs, prices, jobs, articles) into clean JSON.
When NOT to use: Do NOT use for general open-ended chat without a defined schema.

Parameters:
- `url` (string, required): Target webpage URL.
- `schema` (object, required): JSON object describing fields or schema to extract.
- `instructions` (string, optional): Specific guidance for extraction.
- `fetch_stealth_web`: Fetch webpage HTML with modern browser TLS and header impersonation (Sec-Ch-Ua, realistic headers) to bypass bot protection and detect anti-bot challenges. Requires x402 micropayment (0.01 USDC on Base).

When to use: Fetching websites that block standard cURL or basic HTTP libraries with 403 Forbidden.
When NOT to use: Do NOT use for downloading giant binary files (videos, zip archives).

Parameters:
- `url` (string, required): Target webpage URL.
- `custom_headers` (object, optional): Additional HTTP headers to pass along.
- `get_captcha_pricing`: Retrieve current x402 pricing per 1,000 CAPTCHA solves across all supported types (Turnstile, hCaptcha, reCAPTCHA v2, Arkose, Cloudflare). Free endpoint with zero parameters.

When to use: Check current rates and atomic USDC requirements before calling solve_captcha.
When NOT to use: Do NOT use to submit or solve CAPTCHA challenges.
- `read_web_page`: Extract clean, readable Markdown and metadata from any public webpage for LLM ingestion, stripping ads, popups, and navigational clutter. Returns clean markdown, title, description, character count, and estimated tokens. Requires x402 micropayment (0.005 USDC on Base).

When to use: Ingesting articles, blog posts, documentation, or news pages into LLM context.
When NOT to use: Do NOT use for raw binary files (PDF/images), authenticated pages behind a login, or single-page apps that require heavy JavaScript rendering.

Parameters:
- `url` (string, required): Full target webpage URL (e.g. 'https://news.ycombinator.com').
- `include_links` (boolean, optional, default true): Whether to preserve markdown hyperlinks.
- `include_images` (boolean, optional, default false): Whether to preserve image markdown links.
- `search_web`: Execute live web searches using multi-engine chain (TinyFish, DuckDuckGo, Jina) without monthly API subscriptions. Returns fresh source URLs, titles, and snippets. Requires x402 micropayment (0.005 USDC on Base).

When to use: Real-time web browsing and information retrieval for AI agents.
When NOT to use: Do NOT use for deep recursive crawling of entire sites.

Parameters:
- `query` (string, required): Search query (3-300 chars).
- `limit` (integer, optional, default 5): Maximum number of search results to return (1-10).
- `solve_captcha`: Solve web CAPTCHA challenges (Turnstile, hCaptcha, reCAPTCHA v2, Arkose, Cloudflare) and return a valid solution token. Automatically retries once on failure without double charging. Requires x402 payment on Base.

When to use: Use when an agent encounters a bot wall or CAPTCHA challenge during automated web workflows.
When NOT to use: Do NOT use for non-CAPTCHA auth, 2FA/OTP codes, or general login forms.

Parameters:
- `type` (string, required): CAPTCHA type ('turnstile', 'hcaptcha', 'recaptcha', 'arkose', 'cloudflare').
- `sitekey` (string, required): Public sitekey extracted from the target page DOM.
- `url` (string, required): Full target webpage URL hosting the challenge.
- `verify_ai_claim`: Verify whether an AI model, API provider, pricing claim, or infrastructure assertion is true today using live web evidence. Returns deterministic verdicts (TRUE, FALSE, PARTIALLY_TRUE, UNREACHABLE, UNVERIFIED) with cited sources and confidence scores. Requires x402 micropayment (0.01 USDC on Base).

When to use: Fact-checking an AI provider's claims, pricing, or model availability.
When NOT to use: Do NOT use for general open-ended web search, coding assistance, or non-AI claim verification.

Parameters:
- `query` (string, required): The exact claim or assertion to verify (5-500 chars), e.g. 'Is GLM-5.3 Flash free on ZenMux?'.
- `depth` (string, optional, default 'standard'): Verification depth. 'standard' executes fast single-pass search (0.01 USDC); 'deep' conducts multi-source cross-examination (0.03 USDC).
