Input Schema

NameRequiredDescriptionDefault
limitNoMaximum records to return (1-100). Each returned record costs one credit.
roundNoFunding round filters. Canonical values: pre-seed, seed, angel, series-a, series-b, series-c, series-d, series-e, series-f, series-g, series-h, series-i, growth, private-equity, extension, bridge, convertible, safe, debt, grant, pre-ipo, secondary, pipe, other.
sinceNoReturn records announced on or after this date (YYYY-MM-DD) or ISO-8601 timestamp.
untilNoReturn records announced on or before this date (YYYY-MM-DD, inclusive) or ISO-8601 timestamp.
cursorNoOpaque pagination cursor returned as pagination.nextCursor on the previous page.
domainNoCompany domain, e.g. stripe.com. Matches the company's primary domain or any domain it redirected from; a full URL works too.
companyIdNoReturn only events for this entity-resolved company id.
countriesNoHeadquarters country codes (ISO alpha-2, OR). Pass "unknown" to include companies with no country on file.
naicsCodeNoNAICS 2022 code for the company. Matches the code and everything beneath it, so "51" also returns 5132 and 5173. Sector ranges work: "31-33" returns all manufacturing. Any 2- to 6-digit code is accepted; codes deeper than we classify (e.g. 541511) match at their deepest classified parent (5415).
verticalsNoHigh-level sector filters (OR). Canonical values: ai, fintech, saas, devtools, healthcare, climate, robotics, cybersecurity, logistics, commerce, data, crypto, media, education, marketing, telecom, realestate, hardware, gaming, space.
enrichedOnlyNoReturn only rounds whose company resolved, so every result carries a domain, industry and country rather than a bare name. Leave it off for maximum coverage: some markets are reported nowhere else, and those rounds arrive with the company name alone.
includeTotalNoAlso return pagination.total, the number of records matching these filters across all pages. Costs no credits.
maxAmountUsdNoMaximum funding amount in USD.
minAmountUsdNoMinimum funding amount in USD.
industryGroupsNoCompany industry groups (OR). LinkedIn industry labels, matched case-insensitively; older LinkedIn names and short forms like "software" map to the current label. Pass "unknown" for companies with no industry on file.
employeeBucketsNoCompany employee-count buckets (OR). Canonical values: 1-10, 11-50, 51-200, 201-500, 501-1000, 1001-5000, 5001-10000, 10001+.

A3.7/5.0
Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already declare readOnly/destructive/openWorld, so the bar is lower, and the description adds genuinely non-obvious traits: newest-first ordering and, critically, a per-record credit cost that affects how an agent should set limit. It stops short of describing the returned record shape or pagination workflow.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Three short sentences, zero padding: ordering first, filter surface second, cost last. Each sentence carries information an agent would otherwise lack.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a 16-parameter tool with no output schema, the description leaves the shape of a returned funding event (amount currency, round, investors, dates) entirely unexplained, and never mentions the cursor/nextCursor pagination loop. Cost and ordering are covered, so it is adequate but not complete.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so the schema already explains every one of the 16 parameters in detail. The description only names a subset of the filters (round, amount range, country, industry group, company id) without adding syntax or defaults, so baseline 3 applies.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb+resource ('List funding events') plus the sort order, which immediately separates it from siblings like acquisitions or investors. It does not explicitly name an alternative tool, so it falls short of a 5, but the resource noun is distinctive enough to disambiguate.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The filter list implies the use case (find rounds by stage, size, geography, industry, company) but never says when to prefer this over a company-scoped or investor-scoped tool. No exclusions, prerequisites, or alternatives are given.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
