get_public_stats

Read-only

Retrieve public corpus-wide SEC filing statistics—totals for filings, transactions, companies, 13F AUM, and ingestion latency—without an API key. Use for status widgets or marketing dashboards.

Instructions

Public corpus-wide statistics — no API key required. Returns headline dataset totals: filing count, transaction count, tracked companies, institutional holdings rows, Form 144 and Form 13F-HR filing counts, the earliest filing date in the corpus, the most recent quarter's total 13F-HR reported AUM in USD, and measured ingestion latency (median/p95 seconds from SEC acceptance to our processing, trailing 7 days). Use this for corpus-wide totals (e.g. a marketing/status widget), not for per-company or per-insider data — those live under GET /v1/companies and GET /v1/insiders. For freshness and coverage-quality metrics (is ingestion stalled, is price data stale) use GET /v1/data-quality instead. Takes no parameters. No API key or plan required. Cached for ~12 hours.

Behavior4/5

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

Annotations already declare readOnlyHint and openWorldHint. The description adds valuable context: no API key required, cached for ~12 hours, and lists the specific fields returned. Does not contradict annotations.

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

Conciseness4/5

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

The description is front-loaded with purpose and key feature (no API key). It lists the returned fields but could be slightly more concise by grouping related items. Still, every sentence earns its place.

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

Completeness5/5

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

Given zero parameters, no output schema, and clear annotations, the description provides complete context: what it returns, use cases, limitations, caching, and alternatives. No gaps.

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

Parameters4/5

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

No parameters exist, so baseline is 4. Description does not need to add parameter information.

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

Purpose5/5

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

The description clearly states it returns public corpus-wide statistics and distinguishes itself from sibling tools like get_company_overview and get_data_quality by specifying where to find per-company or per-insider data.

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

Usage Guidelines5/5

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

Provides explicit guidance: use for corpus-wide totals (e.g., marketing widget), not for per-company or per-insider data, and suggests alternative endpoints. Also recommends get_data_quality for freshness metrics.

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