# AnswerPool Filing Cadence

> AnswerPool Filing Cadence is a paid API for AI agents from answerpool.io, paid per call via x402, $0.02/call, status unknown (last checked 2026-09-14).

Returns a filer's year-by-year SEC filing counts broken down by form type since 2021, enabling detection of disclosure gaps, spikes, or stopped reporting.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability answerpool-filing-cadence-3cf1ce84
```

Example prompt: Can you pull up the year-by-year SEC filing cadence for Tesla — I want to see how many filings they've submitted per form type each year since 2021 and whether there are any gaps or spikes?

## When to prefer this

Choose this endpoint when you need a high-level summary of how frequently a company has filed with the SEC over time, without enumerating individual filings. It is ideal for detecting stopped reporting, spotting anomalous disclosure spikes, or building a quick disclosure-rhythm profile during due diligence or compliance monitoring. Prefer it over listing-based endpoints when you don't need individual filing details, just aggregate counts per year and form type.

## Known failure modes

- Neither CIK nor ticker provided — returns validation error
- Unknown ticker or CIK not found in EDGAR index — returns empty or null company
- Ticker resolves to multiple CIKs (ambiguous) — may return unexpected filer
- No filings found since 2021 — returns empty years array with zero total_filings
- Payment not included or insufficient — returns HTTP 402 requiring x402 payment of $0.02 USDC

## How this service works

AnswerPool turns SEC EDGAR, the Federal Register, USAspending, NIH, BLS and OpenAlex into structured JSON answers that AI agents and developers fetch in one call. 69 endpoints free, no account; derived analyses $0.02–$0.05 per call by card credits or USDC (x402). MCP server, full provenance.

## Output

A JSON object containing the company name, CIK, index coverage dates, total filings since 2021, and an array of year objects each listing the total count and a breakdown of filing counts by form type (e.g. '10-K': 1, '8-K': 12, '4': 45). Also includes an as_of timestamp and disclaimer.
