API Introduction
This API provides multi-dimensional bidding and tendering data retrieval services. Via POST requests, developers can query full lifecycle information such as tender announcements, winning bid notices, and contract acceptance, based on conditions like keywords, publication time, project region (province/city code), procurement method, and announcement type. It supports both precise and fuzzy search modes, meeting enterprises' data needs for business opportunity discovery and competitor monitoring.
Use Cases
- Business Opportunity Discovery: Sales teams can identify potential tender projects in real-time based on industry keywords and regions.
- Competitor Analysis: Monitor specific companies' winning bid records and participating projects to analyze market share.
- Supply Chain Risk Control: Query suppliers' historical bidding and performance records to assist with qualification reviews.
- Market Intelligence: Compile procurement trends and capital flows in specific industries to support decision-making.
Request and Response Description
Core Request Parameters:
keyword(Required): Search keyword, length must be greater than 2 characters, avoid using overly broad terms.searchMode(Required): 1 for precise search, 2 for fuzzy search.publishStartTime/publishEndTime: Time range format is yyyy-mm-dd, the interval must not exceed one year.announcementType: Differentiates between tender announcements (1) or tender results (2).projectRegionProvinceCode/projectRegionCityCode: Use standard administrative division codes to filter by region.pageSize/pageIndex: Pagination parameters, maximum 10 entries per page.
Response Result: Returns a list of matching bidding and tendering data, including key fields such as project name, number, procuring entity, winning bid amount, and publication time (specific fields are subject to the actual response).
Integration Suggestions
- Keyword Optimization: It is recommended to combine 'entity name + project type' for queries to improve accuracy.
- Time Window Control: Due to the large volume of data, it is recommended to limit the time span to within 3-6 months to avoid single request timeouts.
- Caching Strategy: For historical data queries that do not require extremely high real-time performance, it is recommended to establish short-term caching on the business side to reduce API call frequency.
- Error Handling: Please properly handle parameter validation errors caused by keywords being too short or time intervals exceeding limits.
Integration Examples
Includes ready-to-use Shell, Python, Go, Java, and PHP examples for direct integration.
