Fund Momentum

START HERE for any question about funds. Search actively deploying venture capital funds by stage, country and industry. COST: free, and it works with no API key at all. Returns name, slug, country, stage, fund size, industries and a durable profile URL. The `slug` in each result is what every other tool takes as input, so run this first and copy the slug rather than constructing one from a fund's name.

THEN: get the detailed profile of one fund, using a slug returned by search_funds. COST: free, no API key required. Every response carries a `provenance` block stating where each field came from, when it was last verified, and how confident Fund Momentum is in it. Do not guess the slug from a fund's display name; it will usually be wrong and the call is wasted.

{
  "type": "object",
  "properties": {
    "slug": {
      "type": "string",
      "description": "The slug identifier of a fund, exactly as returned in the `slug` field of search_funds. Call search_funds first rather than guessing: slugs are not derivable from a fund's display name."
    }
  },
  "required": [
    "slug"
  ]
}

FOR STAYING CURRENT, not for discovery: return only the funds whose data changed since a given timestamp. COST: free, no API key required. With no key it reaches back at most 7 days; a free key widens that to 30 days, and a paid caller is not limited. A shortened window is declared as since_floor_applied, never silently truncated. Designed for cheap repeated polling: send the `next_since` AND the `etag` from your previous response, and an unchanged window answers with `unchanged: true` and no rows. Use this instead of re-running search_funds on a schedule. One call here replaces a full re-crawl.

{
  "type": "object",
  "properties": {
    "since": {
      "type": "string",
      "description": "Lower bound, exclusive. Accepts either an ISO 8601 timestamp ('2026-08-01T00:00:00Z') or a unix epoch in milliseconds as a string ('1785955265103'). Omit to receive the last 7 days."
    },
    "if_none_match": {
      "type": "string",
      "description": "The `etag` value from your previous get_changes response. If nothing changed, the reply is a few bytes instead of a full page. This is the cheapest poll available here."
    },
    "limit": {
      "type": "integer",
      "description": "Maximum rows to return (1-200)",
      "default": 50
    }
  }
}

DRILL DOWN on a fund you already identified with search_funds or get_fund. Returns investor signals: GP thesis, bullish and contrarian signals, founder dos and don'ts, deployment status and source URLs. This is the tool to use before writing an outreach message to a specific fund. COST: included in Pro, or €0.10 per call over MPP if you have no key. Roughly 96% of funds carry signals; the rest return not_found BEFORE any payment is taken, so a wrong slug is never charged for.

{
  "type": "object",
  "properties": {
    "slug": {
      "type": "string",
      "description": "The fund's slug, exactly as returned in the `slug` field of search_funds. Call search_funds first rather than guessing."
    }
  },
  "required": [
    "slug"
  ]
}

DRILL DOWN to the people: General Partner profiles for a fund you already identified. Use this when the question is who to approach and what they personally focus on, rather than what the fund does. COST: included in Pro, or €0.10 per call over MPP if you have no key. A fund with no published GP data returns not_found before any payment. Requires a slug from search_funds.

{
  "type": "object",
  "properties": {
    "fund_slug": {
      "type": "string",
      "description": "The fund's slug, exactly as returned in the `slug` field of search_funds. Call search_funds first rather than guessing."
    },
    "gp_name": {
      "type": "string",
      "description": "Optional GP name to filter by"
    }
  },
  "required": [
    "fund_slug"
  ]
}

ALTERNATIVE ENTRY POINT when you do not know what to search for. Describe a startup in plain language and receive the top 10 matching funds, each with a slug, a reason and a score. Use this instead of search_funds when the brief is qualitative ('climate hardware, pre-seed, Europe') rather than a filter. Slower than the other tools, three to ten seconds, because it reasons over every tracked fund: allow for that before you time out and retry. COST: included in Pro, or €0.25 per call over MPP if you have no key.

{
  "type": "object",
  "properties": {
    "description": {
      "type": "string",
      "description": "Startup description (max 500 chars)"
    },

    },
    "country": {

START HERE for any question about limited partners (LPs). Answers "does Fund Momentum cover my geography and LP type" with COUNTS ONLY: how many disclosed LPs match, and how many of those have backed emerging managers. It never returns a name, slug, website or commitment. COST: free, works with no API key at all (counts against the keyless daily allowance), and is never billed to agent credits or a monthly quota. Counts below 5 are reported as "<5" and zero as "none". Call this before search_lps to find out whether LP Radar covers what you need.

{
  "type": "object",
  "properties": {
    "country": {
      "type": "string",
      "description": "Headquarters country of the LP, spelled out in full (e.g. 'Germany', 'United States'). Two-letter ISO codes are accepted too. LPs whose headquarters is undisclosed are never counted under a country; they are reported separately as undisclosed_hq_count."
    },
    "lp_type": {
      "type": "string",
      "enum": [
        "Pension fund",
        "Insurer",
        "Foundation / Endowment",
        "University / Research",
        "Bank",
        "Public / State institution",
        "Sovereign wealth fund",
        "Fund-of-Funds",
        "Asset manager / Investment firm",
        "Family office / Holding",
        "Corporate / Strategic",
        "Impact investor",
        "Investment vehicle",
        "Individual / Angel",
        "Institutional LP"
      ],
      "description": "LP type. Must be one of the listed values; common spellings such as 'family office', 'pension' or 'fund of funds' are accepted and normalised."
    }
  }
}

THEN, for LP Radar subscribers: return limited partner records (name, slug, LP type, HQ country and city, geographic focus, website, emerging-manager backing, verified flag) filtered by country, LP type and emerging-manager backing, at most 25 per call. Set backs_emerging_managers=true to see only LPs that have already backed a first or second fund — for a first-time manager that is usually the only filter that matters. Requires LP Radar (EUR 199 per month or EUR 1,499 per year, https://fundmomentum.vc/lp-radar). Not available per call, on agent credits or on the keyless trial. Unlimited calls for subscribers. Use check_lp_coverage first — it is free and tells you whether the dataset covers your geography and LP type before you pay anything. Send the API key of the account that holds LP Radar. A caller without it gets error_reason "lp_access_required" together with the coverage count for its filters, never a payment challenge. website is null when no website is on record; it is never omitted.
