News Search Parameters

Important: You need to understand the user's query intent and perform word segmentation, then combine them using OR/AND to form search keywords, supporting both Chinese and English.

Strategy History Operations

These authenticated endpoints query the current user's strategy configuration and historical strategy-triggered events. Each call consumes 1 quota. Create and manage strategies at https://www.newsliquid.com/strategy.

1. Get Strategy List

curl -s -H "Authorization: Bearer $OPENNEWS_TOKEN" \
  "https://ai.6551.io/open/strategy_list?page=1&limit=20"

Returns only id, name, description, enabled, and createdAt for each strategy.

2. Get Strategy Hits

curl -s -H "Authorization: Bearer $OPENNEWS_TOKEN" \
  "https://ai.6551.io/open/strategy_hits?strategyId=42&page=1&limit=20"

Returns historical triggered events for the given strategy ID. Each hit uses the same news-like payload shape as the WebSocket strategy.triggered event, including nested strategy, coins, optional aiRating, source, description, relatedAddress, and triggered metric fields when available.

WebSocket news_wss Protocol

Connect with the token in the query string:

wss://ai.6551.io/open/news_wss?token=$OPENNEWS_TOKEN

Supported client messages:

Server-pushed events:

news.subscribe controls news.update and news.ai_update. strategy.triggered is automatically delivered to the authenticated strategy owner and does not need a separate subscribe method.

Subscribe example:

{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "news.subscribe",
  "params": {
    "engineTypes": {
      "news": ["Bloomberg", "CoinDesk"],
      "onchain": []
    },
    "coins": ["BTC", "ETH"],
    "hasCoin": true
  }
}

Unsubscribe example:

{
  "jsonrpc": "2.0",
  "id": 2,
  "method": "news.unsubscribe"
}

Finance Enhancement Entity Protocol

These authenticated endpoints provide company discovery, report catalogs, report text, key market events, public stock-disclosure evidence, and wallet-visible on-chain evidence. Responses are wrapped as {"success": true, "data": ...} and may include usage quota metadata. Treat data.status as the business result; HTTP success alone does not mean the company, report, or disclosure query was resolved.

Resolve the Company Before Reading Reports

Company names can legitimately map to more than one issuer or listed security. Use this sequence:

user company expression
→ broad company-search
→ inspect ambiguity_candidates[]
→ choose the intended market/issuer
→ retry with one exact identifier namespace
→ read company-info
→ choose report_id + report_type
→ read company-report-text

Never send a fuzzy company name together with an exact identifier. Exactly one company selector must be authoritative.

The OpenNews MCP tools accept any one of these selectors directly:

The raw HTTP endpoints use the generic form identifier + identifier_type + market. Do not send cik, ticker, dart_corp_code, krx_stock_code, or canonical_issuer_id as standalone HTTP JSON fields: those are MCP conveniences. Convert stable IDs as follows:

Company Search

Use a name only for discovery. An ambiguous_entity response is expected when multiple markets or issuers match.

curl -s -X POST "https://ai.6551.io/open/finance-enhance/company-search" \
  -H "Authorization: Bearer $OPENNEWS_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"keyword":"Hynix","identifier_type":"company_name","market":"GLOBAL","result_scope":"issuer","limit":20,"auto_collect":false}'

For SK hynix this can return both the U.S. SEC issuer (SEC:0002120882, including ticker SKHY) and the Korean DART issuer (DART:00164779, security KRX:000660). Choose from the user's requested market; do not silently take the first candidate.

Company Info

Returns the resolved identity and available SEC/DART filings, third-party research reports, earnings-call transcripts, report forms, and financial item names.

U.S. SEC issuer:

curl -s -X POST "https://ai.6551.io/open/finance-enhance/company-info" \
  -H "Authorization: Bearer $OPENNEWS_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"identifier":"0002120882","identifier_type":"cik","market":"US","auto_collect":false,"filing_limit":50,"fact_limit":1000}'

Korean DART issuer:

curl -s -X POST "https://ai.6551.io/open/finance-enhance/company-info" \
  -H "Authorization: Bearer $OPENNEWS_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"identifier":"00164779","identifier_type":"dart_corp_code","market":"KR","auto_collect":false,"filing_limit":50,"fact_limit":1000}'

Verify the returned canonical_issuer_id, market, matched_by, and match_confidence before using any report catalog entry.

Company Report Text

Prefer the stable report_id and report_type returned by company-info. Report types are SEC, DART, RESEARCH, and TRANSCRIPT.

curl -s -X POST "https://ai.6551.io/open/finance-enhance/company-report-text" \
  -H "Authorization: Bearer $OPENNEWS_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"identifier":"0002120882","identifier_type":"cik","market":"US","report_id":"<catalog report_id>","report_type":"RESEARCH","max_section_chars":50000,"auto_collect":false}'

Before treating text as evidence, verify that the response company, selected report canonical_issuer_id, report_id, and report_type all match the chosen catalog entry.

Business statuses include ok, invalid_input, selector_conflict, ambiguous_entity, entity_not_found, report_not_found, text_not_cached, section_not_found, unsupported, partial_result, and upstream_error. For ambiguous_entity, use ambiguity_candidates[] and the returned resolution hint to retry with one exact selector.
