• 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.

  Parameters:

  • task (required) — string — What you're trying to find or do, in your own words

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• 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.

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• 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.

  Parameters:

  • description (required) — string — What data you need, in your own words
  • contact — string — Optional: URL/email/handle for follow-up
  • use_case — string — Optional: what you're building

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• email_check

  Deliverability signals for one address: RFC5322 syntax, live MX/SPF/DMARC over DNS-over-HTTPS, disposable/role-account flags. Signals with evidence — not a guaranteed inbox verdict. 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.

  Parameters:

  • email (required) — string — The address to check.
  • x_payment — string — 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.

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• phone_check

  Validate and normalize a phone number: E.164 form, line type, region, and a verdict. Pure CPU, no third-party lookup. 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.

  Parameters:

  • number (required) — string — The number, ideally in E.164.
  • region — string — ISO-3166 region hint for national-format numbers.
  • x_payment — string — 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.

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• domain_intel

  RDAP registration card for a domain (creation/expiry dates, registrar, statuses, nameservers, DNSSEC) plus derived risk flags like domain age. view='dns' returns a live multi-record DNS summary (A/AAAA/CNAME/MX/NS/TXT/SOA/CAA + SPF/DMARC); view='live' re-reads the registry at the moment you ask. 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.

  Parameters:

  • domain (required) — string — Registrable domain name.
  • view — string — Which read to perform.
  • x_payment — string — 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.

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• url_screen

  Screen a URL against the URLhaus blocklist snapshot plus deterministic live heuristics (redirect chain, host reputation signals, lookalike patterns). Returns a verdict with the rules that fired. 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.

  Parameters:

  • url (required) — string — Absolute URL to screen.
  • follow — boolean — Follow the redirect chain before judging.
  • x_payment — string — 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.
