Server tool list (12)
Raw names from tools/list. Only developers need these.
| find_data | 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. |
| pricing | Every endpoint this server fronts, with its exact per-call USD price (x402, USDC on Base) and a one-line summary, read live from the route table. Free. |
| coverage | Corpus coverage: which SEC datasets exist, 10-K backfill progress by quarter (2015→now), and — given a ticker — which fiscal years are on file for it. Free. |
| request_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. |
| sec_filing_section | Parsed sections of a SEC filing by ticker or CIK: 10-K (default), 10-Q, or 8-K. Sections like business, risk_factors, mdna. Corpus 2015→now; missing filings can be requested via request_data. Example: {ticker:'AAPL', selector:'2023', sections:'risk_factors,mdna'}. 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. |
| insider_activity | Insider buy/sell activity. With a ticker: that company's summary (net buys/sells, top insiders). Without: the most recent filings market-wide.
