# Otto AI 8-K Material Events Feed > Otto AI 8-K Material Events Feed is a paid API for AI agents from x402.ottoai.services, paid per call via x402, $0.003/call, status unknown (last checked 2026-09-14).

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 otto-ai-8-k-material-events-feed-0156d79e ``` Example prompt: Pull all SEC Form 8-K material event filings for NVDA from the last 90 days — I want the item codes like 1.01 material agreements or 1.05 cybersecurity incidents, event dates, and EDGAR links. ## When to prefer this Use this endpoint when you need structured, item-coded SEC Form 8-K data for a specific US-listed company without parsing raw EDGAR filings yourself. It is ideal for compliance monitoring, material event alerting, corporate governance research, M&A due diligence, and portfolio surveillance. Prefer this over raw EDGAR EDGAR full-text search when you want pre-classified item codes (e.g. 1.05 cybersecurity, 5.02 officer change, 3.01 delisting) and clean metadata rather than unstructured filing documents. ## Known failure modes - Invalid or unrecognized ticker symbol returns an error or empty filings array - Company has no 8-K filings in the 90-day lookback window, returning empty filings list - EDGAR data lag may mean very recently filed 8-Ks are not yet reflected - Earnings-only 8-K filings are excluded by default (earningsOnlyExcluded count reported in coverage) - Foreign private issuers or non-US-listed tickers may not be supported - Response truncated at 20 filings max if company filed more than 20 8-Ks in the window ## How this service works 8-K filings by ticker — the item-coded SEC material-event feed: every 8-K a US-listed company filed in 90 days, tagged with the SEC's own item codes and official titles (1.01 material agreement, 1.05 cybersecurity incident, 3.01 delisting notice, 5.02 officer change, 8.01 other). Returns event and filing dates separately, amendments labelled, EDGAR links. Earnings-only filings excluded and counted. Public-domain SEC EDGAR. $0.003 per call. ## Output A JSON object containing the issuer's CIK and name, the queried ticker, a 90-day lookback window, an array of 8-K filings each with EDGAR URL, form type, SEC item codes (numbered codes with titles and section metadata), filing date, event date, accepted timestamp, amendment flag, accession number, and an earnings-item flag. Also includes a summary of item code frequencies, filing counts, amendment counts, date ranges, and coverage metadata (truncation status, candidates in window, earnings-only exclusions). ## Request schema (JSON Schema) ```json { "type": "object", "$schema": "https://json-schema.org/draft/2020-12/schema", "required": [ "input" ], "properties": { "input": { "type": "object", "required": [ "type", "method" ], "properties": { "type": { "type": "string", "const": "http" }, "method": { "enum": [ "GET" ], "type": "string" }, "queryParams": { "type": "object", "required": [ "ticker" ], "properties": { "ticker": { "type": "string", "description": "US-listed stock ticker symbol (e.g. NVDA, GME, MSTR)" } } } }, "additionalProperties": false }, "output": { "type": "object", "required": [ "type" ], "properties": { "type": { "type": "string" }, "example": { "type": "object", "required": [ "status" ], "properties": { "data": {}, "meta": { "type": "object" }, "reason": { "type": "string", "description": "status=unavailable only; every >=400 is UNCHARGED" }, "status": { "enum": [ "success", "unavailable" ], "type": "string" } } } } } } } ``` ## Response schema (JSON Schema) ```json { "type": "json", "example": { "data": { "note": "The material events this company reported to the SEC on Form 8-K, each c...", "issuer": { "cik": "1045810", "name": "NVIDIA CORP" }, "ticker": "NVDA", "window": { "end": "2026-09-01", "start": "2026-06-03", "lookbackDays": 90 }, "caveats": [ { "code": "eight_k_item_codes_not_contents", "plain": "This endpoint returns WHICH material events a company reported and when,...", "affects": [ "filings" ] } ], "filings": [ { "url": "https://www.sec.gov/Archives/edgar/data/1045810/000104581026000069/", "form": "8-K", "items": [ { "code": "1.01", "known": true, "title": "Entry into a Material Definitive Agreement", "section": 1, "sectionTitle": "Registrant's Business and Operations" } ], "filedAt": "2026-08-17", "eventDate": "2026-08-17", "acceptedAt": "2026-08-17T12:41:33.000Z", "isAmendment": false, "accessionNumber": "0001045810-26-000069", "includesEarningsItem": false, "primaryDocDescription": "8-K" } ], "summary": { "itemCounts": [ { "code": "9.01", "known": true, "title": "Financial Statements and Exhibits", "filingsWithItem": 2 } ], "filingCount": 4, "latestFiledAt": "2026-08-17", "amendmentCount": 0, "earliestFiledAt": "2026-06-18", "latestEventDate": "2026-08-17", "unknownItemCodes": 0, "distinctItemCodes": 6, "earliestEventDate": "2026-06-15", "filingsWithEarningsItem": 0 }, "coverage": { "truncated": false, "lookbackDays": 90, "filingsServed": 4, "maxFilingsServed": 20, "subjectIsRegistrant": true, "candidatesInLookback": 5, "earningsOnlyExcluded": 1, "lookbackFullyCovered": true, "filingsWithoutItemCodes": 0 }, "generatedAt": "2026-09-01T12:00:00.000Z", "methodology": "https://docs.useotto.xyz/acp-swarm/sec-filings-methodology" }, "meta": { "dataAsOf": "", "degraded": false, "validUntil": "", "generatedAt": "", "stalenessSec": 0 }, "status": "success" } } ``` ## More - Live health (JSON, refreshed every minute): https://www.zero.xyz/c/otto-ai-8-k-material-events-feed-0156d79e/health.json - [Zero catalog index](https://www.zero.xyz/llms.txt) - [Other services from x402.ottoai.services](https://www.zero.xyz/host/x402.ottoai.services/llms.txt)
