How this service works
Rank every SEC filer on one XBRL metric for one period — top-N values with entity names and the total filer count, from the frames API. Use for whole-market screens without a bulk XBRL pipeline; one MCP incumbent exists for xbrl. Pay per call (x402 USDC or prepaid card credits); no subscription, no API key signup.
Output
Returns a JSON object containing the XBRL tag name, the requested metric slug, the period, an as-of timestamp, the total number of filers that reported the metric, and an array of top-N rows each with the company's CIK, entity name, and reported numeric value. Also includes a disclaimer noting the data is derived from public SEC EDGAR filings.
Example use cases
Whole-market revenue ranking screen
“Show me the top 100 public companies ranked by Revenues for the full year CY2024 — include their names, CIK numbers, reported values, and how many companies total filed that metric.”
R&D spend competitive benchmark
“Rank all SEC filers by ResearchAndDevelopmentExpense for CY2023 and give me the top 50 — I want to see who's spending the most on R&D market-wide.”
Quarterly earnings per share leaderboard
“Get me the top 200 companies by EarningsPerShareBasic for CY2024Q1 with entity names and values, and tell me how many total filers reported that XBRL tag.”

Endpoint
GEThttps://answerpool.io/v1/sec/xbrl/frame?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a whole-market financial ranking on a single XBRL metric without building or maintaining a bulk XBRL data pipeline. It is ideal for market screening, competitive benchmarking, and sector analysis where you want to see how all SEC filers stack up on one standardized financial concept for a specific calendar period. Prefer it over company-specific XBRL endpoints when the goal is cross-company comparison rather than deep-diving a single filer.
Side effects
- Invalid metric name returns an error or empty result if no XBRL tag matches
- Invalid period format (must match CY####, CY####Q#, or CY####Q#I) returns a validation error
- Period with no available XBRL frame data returns empty top array
- Limit outside 1–200 range returns a validation error
- Payment failure (x402) blocks the request if USDC funds are insufficient
- SEC EDGAR frames API lag may mean very recent periods return no data yet
