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.
