Company Facts

Find which applicant-tracking system a company's careers page runs on. Greenhouse, Ashby, Lever and Workable all publish open job board APIs, and all of them are unusable unless you already know the company's board name. None publishes a directory of its customers, and none could, since no vendor knows about the others. Use this first when you have a company name rather than a careers URL.

{
  "type": "object",
  "properties": {
    "company": {
      "type": "string",
      "description": "Company name or board name, for example 'anthropic' or '1Password'. Case and punctuation do not matter."
    },
    "limit": {
      "type": "integer",
      "minimum": 1,
      "maximum": 100,

    }
  },

Every open job at one company, read from its own careers system. Returns title, department, location, employment type, workplace type, posted date, a parsed salary range where the employer publishes one, and a verify_url pointing at the employer's own advert. Salaries are refused rather than guessed: an hourly rate, an ambiguous currency, or bands in two currencies all yield no figure, and salary_text keeps whatever the employer wrote.

{
  "type": "object",
  "properties": {
    "company": {
      "type": "string",
      "description": "A board name ('stripe'), a careers URL ('https://jobs.ashbyhq.com/ramp'), or system:name ('ashby:ramp')."

Open jobs across several companies at once, in one schema. This is the thing no single applicant-tracking system can do: each vendor only knows about its own customers. Companies on different systems come back with the same field names. One company failing does not lose the others.

What changed in hiring, day by day: jobs newly posted, taken down, reopened, or edited (title, location or salary), read daily from every job board in the directory. Call it each day with since set to the last day you saw, rather than re-reading every board. Omit companies for the whole market, or filter by kind and title words.

Any public web page or PDF as clean markdown, with its title and final URL after redirects, plus the page's schema.org data (prices, dates) when it has any. robots.txt is honored. Some sites refuse automated readers; those calls fail with the reason and cost nothing.

Read a web page and return the named fields as JSON, using only what the page states; a value the page does not give comes back empty rather than guessed. Name fields, or pass a JSON Schema, or neither for a title, summary and key points. Needs an API key (5 calls from its balance); a failed extraction is refunded.

Is this address worth sending to: syntax, whether the domain exists and has mail servers, and whether it is a throwaway, role (info@, sales@) or free-provider address. It never contacts the mailbox, so a missing mailbox at a real domain still passes, and the answer says so.

Fetch one web page and report the technologies behind it (CMS, ecommerce platform, analytics, CDN, web server, frameworks, payment processors, email provider) with a confidence and the evidence for each.

Checks one VAT number against the European Commission's VIES service and returns whether it is a live registration and, where the member state shares it, the registered name.

Searches the official Secretary of State business registers of New York, Colorado, Oregon, Connecticut and Pennsylvania, in one record format. mode new is a feed of entities formed in a date window, newest first: use it for new-business leads (LLCs and corporations that just registered) and prospecting. mode search finds entities by legal name and mode lookup by the state's own entity number: use them for KYB (know your business) checks on a supplier or counterparty, to confirm it exists, its type, status (active, delinquent, inactive) and formation date. Every record links to the state's own data row. Never returns officers, directors, individual registered agents, emails, phones or street addresses: business city, state and ZIP only. Each record carries the company's website when one was found with proof (its own pages show the exact legal name and the same city or state), else 'no website found'. New York, Oregon and Pennsylvania publish active entities only, so a missing entity there may be inactive or unregistered. Pennsylvania publishes monthly, so its newest entities are weeks old. If one state fails the others still return and the failure is listed in missing.

Say what you need in plain words ('verify an email', 'read a web page', 'company record for a domain') and get the x402 endpoints that do it, best first, ranked only on public facts: wallets that paid it more than once in the last 30 days (Coinbase's CDP catalog), whether it answered our unpaid request with a 402 last night, its price, and PayAI's uptime. Each result has the price, networks, method, and links to re-check every number. No match is never charged.
