    The QuantFlow API.

    QuantFlow publishes its open roles as JSON so you do not have to scrape the careers page. No API key, no sign-up, no rate limit on reads. The same data renders on /careers, so there is nothing to gate.

    Quickstart

    One request, no key.

    Every endpoint is public, read-only and CORS-enabled, so it works from a browser, a server, or an agent tool call. Responses are cached for five minutes at the edge.

    curl https://www.quant-flow.com/api/jobs

{
  "object": "list",
  "total": 3,
  "limit": 50,
  "offset": 0,
  "data": [
    {
      "slug": "algorithmic-trader",
      "title": "Algorithmic Trader",
      "location": "Amsterdam, Netherlands",
      "url": "https://www.quant-flow.com/careers/algorithmic-trader",
      "apply_url": "https://www.quant-flow.com/apply?job=algorithmic-trader"
    }
  ]
}
    Reference

    Endpoints.

    Three endpoints, each with a unique operation ID and a typed response schema in the OpenAPI document.

    GET/api

    Endpoint directory, with a link to the OpenAPI document.

    operationId: listEndpoints
    curl https://www.quant-flow.com/api

    GET/api/jobs

    Open roles, newest first. Filter with q and location, page with limit and offset.

    operationId: listJobs
    curl 'https://www.quant-flow.com/api/jobs?q=c%2B%2B&limit=10'

    GET/api/jobs/{slug}

    One role by slug. Slugs come from listJobs.

    operationId: getJob
    curl https://www.quant-flow.com/api/jobs/algorithmic-trader
    Errors

    Every failure is JSON.

    Including 404s and 405s. Branch on code; it is stable. message and hint are for humans and for agents deciding what to do next.

    {
  "code": "job_not_found",
  "error": "job_not_found",
  "message": "No open role is published with slug \"foo\".",
  "hint": "List the current roles with GET /api/jobs. Roles are removed once filled.",
  "docs": "https://www.quant-flow.com/developers"
}
    invalid_query_parameter400limit or offset is out of range.
    invalid_slug400The slug is missing or longer than 200 characters.
    job_not_found404No open role with that slug. Roles are removed once filled.
    unknown_endpoint404No endpoint is published at that path.
    method_not_allowed405The endpoint is read-only. Check the Allow header.
    rate_limited429Too many writes from one address. Applies to the form endpoints.
    upstream_unavailable502The job board is temporarily unreachable. Retry in a minute.
    For agents

    Built to be called.

    • Function calling. Every operation has a unique operationId, a description, typed parameters and a response schema, so openapi.json converts to tool definitions without hand-editing.
    • Markdown. Every page on this site is available as markdown per acceptmarkdown.com: send Accept: text/markdown, or append .md to any path.
    • When to use QuantFlow. llms.txt names the jobs QuantFlow is right for, and the ones it is not.
    • Confidential mandates. Most senior searches never appear on the API. An empty list is not an empty desk, so route the user to /contact rather than telling them QuantFlow is not hiring.
    • Do not auto-submit. The apply and contact endpoints accept writes from people. Hand the user the link; do not post an application on their behalf.
    Support

    Something missing from the API?

    There is no ticketing system and no support tier. Email hello@quant-flow.com and a person answers. Breaking changes get a new major version and the old one keeps working; additive fields do not.
