12 tools
find_data
Find the right data source
Describe the data you need in plain language (e.g. 'Apple risk factors 2023', 'is this token a honeypot', 'is this email deliverable', 'read this page'). Searches this server's datasets first, then the whole Professor Sausages catalog, and returns matching endpoints with method, URL, price, and how to call them. Free.
Input schema 
{'type': 'object', 'required': ['task'], 'properties': {'task': {'type': 'string', 'examples': ['Apple risk factors 2023'], 'description': "What you're trying to find or do, in your own words"}}}
holidays
Market calendars & settlement dates
Is a market open on a date, and why not if it isn't. view='next_session' finds the next open day; view='settle' computes a T+N settlement date skipping weekends and holidays; view='business_days' counts open sessions in a range; view='year' lists a calendar's whole year. Paid: call without x_payment to receive this call's exact terms (amount, asset, network), sign them, then call again with x_payment. The free `pricing` tool lists every price at once.
Input schema 
{'type': 'object', 'properties': {'to': {'type': 'string', 'format': 'date', 'examples': ['2026-07-31'], 'description': "Range end (view='business_days')."}, 'date': {'type': 'string', 'format': 'date', 'examples': ['2026-07-03'], 'description': 'Reference date (YYYY-MM-DD).'}, 'days': {'type': 'integer', 'default': 2, 'examples': [2], 'description': "N in T+N (view='settle')."}, 'from': {'type': 'string', 'format': 'date', 'examples': ['2026-07-01'], 'description': "Range start (view='business_days')."}, 'view': {'enum': ['is_open', 'next_session', 'settle', 'business_days', 'year'], 'type': 'string', 'default': 'is_open', 'examples': ['is_open'], 'description': 'Which calendar question to answer.'}, 'year': {'type': 'integer', 'examples': [2026], 'description': "Calendar year (view='year')."}, 'market': {'enum': ['nyse', 'us-federal', 'lse', 'target2', 'weekend-only'], 'type': 'string', 'default': 'nyse', 'examples': ['nyse'], 'description': 'Which calendar to use.'}, 'x_payment': {'type': 'string', 'description': 'Optional signed x402 payment payload (base64, what the X-PAYMENT header carries). Omit to receive the exact payment terms; sign them (e.g. @x402/fetch) and call again with this argument to settle and get the data.'}}}
image_to_text
OCR or describe an image
Transcribe an image to text (OCR) or describe it via a vision model — steerable with your own prompt. Paid: call without x_payment to receive this call's exact terms (amount, asset, network), sign them, then call again with x_payment. The free `pricing` tool lists every price at once.
Input schema 
{'type': 'object', 'required': ['url'], 'properties': {'url': {'type': 'string', 'examples': ['https://raw.githubusercontent.com/python-pillow/Pillow/main/Tests/images/hopper.png'], 'description': 'URL of the image.'}, 'prompt': {'type': 'string', 'examples': ['Describe this image in one sentence.'], 'description': 'What to do with it; omit for a straight transcription.'}, 'x_payment': {'type': 'string', 'description': 'Optional signed x402 payment payload (base64, what the X-PAYMENT header carries). Omit to receive the exact payment terms; sign them (e.g. @x402/fetch) and call again with this argument to settle and get the data.'}, 'max_tokens': {'type': 'integer', 'default': 512, 'examples': [512], 'description': 'Output cap.'}}}
news
Headlines and news search
Newest headlines from a deduped, tiered direct-feed pile (official press, wires and majors). Pass q to keyword-search the retained multi-day archive instead; category='ai' or 'crypto' return the high-signal curated cuts. Snapshot of ingested feeds, not a live web search. Paid: call without x_payment to receive this call's exact terms (amount, asset, network), sign them, then call again with x_payment. The free `pricing` tool lists every price at once.
Input schema 
{'type': 'object', 'properties': {'q': {'type': 'string', 'examples': ['stablecoin regulation'], 'description': 'Keyword query — switches to archive search.'}, 'limit': {'type': 'integer', 'default': 10, 'examples': [10], 'description': 'Max headlines.'}, 'since': {'type': 'string', 'format': 'date-time', 'examples': ['2026-07-21T00:00:00Z'], 'description': 'Only items after this instant (ai/crypto cuts).'}, 'category': {'enum': ['world', 'business', 'technology', 'ai', 'crypto', 'markets', 'health', 'science', 'energy', 'politics', 'climate', 'sports'], 'type': 'string', 'examples': ['technology'], 'description': "Headline category; 'ai' and 'crypto' are curated high-signal cuts."}, 'x_payment': {'type': 'string', 'description': 'Optional signed x402 payment payload (base64, what the X-PAYMENT header carries). Omit to receive the exact payment terms; sign them (e.g. @x402/fetch) and call again with this argument to settle and get the data.'}}}
news_batch
Several news reads in one paid call
Up to 10 headlines / ai / crypto / search reads behind ONE payment (POST /news/batch). Each request names a `route` and carries that route's own parameters — including `since` with a cursor, so one batch can advance several polls at once. `data.results[i]` is exactly the single-route answer for `requests[i]`, in order, each with its own `next_cursor` to store per feed. Every element is validated before any payment is asked for. Paid: call without x_payment to receive this call's exact terms (amount, asset, network), sign them, then call again with x_payment. The free `pricing` tool lists every price at once.

Omit to receive the exact payment terms; sign them (e.g. @x402/fetch) and call again with this argument to settle and get the data.'}}}
news_poll
Poll the news for what's new since your last call
The polling loop for a news-watching agent. First call: omit `since` — you get the current page plus a `next_cursor`. Every later call: pass that `next_cursor` as `since` and receive ONLY articles ingested after it, oldest first, plus the next cursor to store. Follow the whole pile (optionally one `category`) or a curated high-signal `topic` tape (ai, crypto). The pile refreshes every 15 minutes (`suggested_interval_seconds`); dedupe by article `id`, and by `cluster_id` to keep one record per story. A poll with nothing new is still a complete answer (new_count 0, cursor unchanged). Full loop + a paying Node poller: /skills/news.md. Paid: call without x_payment to receive this call's exact terms (amount, asset, network), sign them, then call again with x_payment. The free `pricing` tool lists every price at once.

pdf_extract

Input schema 
{'type': 'object', 'properties': {}}
read_url
Read a page as markdown
Render a URL in a real headless browser (JavaScript executed) and return clean, LLM-ready markdown. Use this when fetch() gives you an empty shell or a bot wall. Paid: call without x_payment to receive this call's exact terms (amount, asset, network), sign them, then call again with x_payment. The free `pricing` tool lists every price at once.

Omit to receive the exact payment terms; sign them (e.g. @x402/fetch) and call again with this argument to settle and get the data.'}}}
request_data
Request missing data
The suggestion box: ask for data we don't have (a pre-2015 filing, an uncovered ticker, an unsupported chain, a whole dataset). Requests feed the nightly ingestion queue — filings are usually available within ~24h. Include contact if you want to hear back. Free.

timezone

weather
Weather now, forecast, or alerts
