APIMon
Apimon v2.0.0 — a devtools command-line toolkit for checking, validating, generating, formatting, linting, explaining, converting, templating, diffing, previewing, fixing, and reporting on API-related tasks. All operations are timestamped and logged, with built-in search, statistics, and multi-format export.

How It Works
Each command (check, validate, generate, format, etc.) works as a timestamped log recorder:
- With arguments: saves the input to
~/.local/share/apimon/\x3Ccommand>.logwith a timestamp, then confirms the entry count. - Without arguments: displays the 20 most recent entries from that command's log file.
All activity is also recorded in a central history.log for cross-command traceability.
Data Storage
- Location:
~/.local/share/apimon/ - Log files: One
.logfile per command (e.g.,check.log,validate.log,format.log) - History:
history.log— central activity log across all commands - Export:
export.json,export.csv, orexport.txtgenerated on demand - Format: Each log line is
YYYY-MM-DD HH:MM|\x3Cinput>
Requirements
- Bash (4.0+)
- Standard Unix utilities (
wc,du,grep,tail,head,date) - No external dependencies or API keys required
When to Use
- API health monitoring — use
apimon check "GET /health returned 200 in 45ms"to log each endpoint check with response details - Schema validation tracking — run
apimon validate "OpenAPI spec v3.1 passed all rules"to record validation outcomes over time - Generating mock data records — use
apimon generate "Mock /users response with 50 entries"to log data generation tasks - Linting API definitions — run
apimon lint "spectral lint passed for orders.yaml"to track lint history - Uptime reporting — use
apimon report "Daily uptime: 99.97%"to log uptime metrics, thenapimon export jsonto build dashboards
Examples
# Check an API endpoint
apimon check "GET https://api.example.com/health — 200 OK, 32ms"
# Validate a response schema
apimon validate "POST /orders response matches OrderSchema v2"
# Generate mock data
apimon generate "10 sample user objects for /api/users"
# Format an API response
apimon format "pretty-print JSON response from /api/products"
# Lint an API spec
apimon lint "openapi-lint passed for petstore.yaml"
# Explain an HTTP status
apimon explain "502 Bad Gateway — upstream server not responding"
# Convert request format
apimon convert "curl command to Python requests"
# Create a request template
apimon template "GET with auth headers and pagination"
# Diff two API versions
apimon diff "v1 vs v2 breaking changes in /users endpoint"
# Preview a request
apimon preview "GET /api/search?q=test&limit=20"
# Record a fix
apimon fix "resolved timeout issue on /api/export endpoint"
# Generate a report entry
apimon report "Weekly API health summary: 99.9% uptime"
# View summary statistics
apimon stats
# Export all data as CSV
apimon export csv
# Search for keywords
apimon search "timeout"
# View recent activity
apimon recent
# Health check
apimon status
Output
Results go to stdout. Save with apimon export json > backup.json. All entries are persisted to the data directory for later retrieval and analysis.
