  ConceptNet is a free, open-source knowledge graph with no paid API tiers.
  Cost management for ConceptNet usage centers on staying within public API
  rate limits or planning the infrastructure required for a self-hosted
  deployment.
model: free-open-source
costDrivers:
  - name: Public API Usage
    description: >-
      The hosted public API at api.conceptnet.io has no monetary cost.
      The primary cost driver is staying within the 3,600 requests/hour
      rate limit. /related and /relatedness endpoints count double against
      the quota.
    cost: $0
    unit: per request
  - name: Self-Hosted Infrastructure
    description: >-
      Running a local ConceptNet instance requires significant hardware.
      Minimum 30 GB RAM is needed to load the database. Additional storage
      is required for the full data download (~30 GB compressed).
    cost: variable
    unit: cloud or on-premise compute
optimizationStrategies:
  - name: Cache Responses
    description: >-
      Cache concept lookups and query results locally. ConceptNet's
      knowledge graph is relatively static, making aggressive caching
      safe and effective for reducing repeated API calls.
  - name: Batch Queries Efficiently
    description: >-
      Use the /query endpoint with combined parameters (node, rel, start,
      end) to fetch all relevant edges in a single request rather than
      chaining multiple node lookups.
  - name: Avoid Double-Counting Endpoints
    description: >-
      The /related and /relatedness endpoints each consume 2 rate-limit
      credits. Use node lookups and local edge traversal when possible
      to preserve quota for relatedness computations.
  - name: Self-Host for High Volume
    description: >-
      For applications requiring more than 3,600 requests/hour, download
      the ConceptNet data dump and run a local instance to eliminate
      rate limits entirely.
  - name: Download Data Dumps
    description: >-
      For batch processing or offline analysis, download ConceptNet data
      files from the downloads page rather than making thousands of API
      calls. Data is available in CSV and JSON-LD formats.
