Reliability & compatibility
Declared compatibility
Compatibility is declared by the source manifest. End-to-end runtime verification is coming, see below.
We're building live execution health for every listing: tool-call success rate, median latency, uptime, and last-checked timestamps, measured, not self-reported. It isn't live yet, so we don't show numbers we can't stand behind.

API Endpoint Testing
Interactive testing of API endpoints with validation of responses.
Steps
- Identify the endpoint:
- URL, HTTP method, required headers
- Authentication: Bearer token, API key, cookie, or none
- Request body format: JSON, form data, multipart
- Expected response: status code, content type, shape
- Test the happy path:
- Send a request with valid inputs
- Verify: status code matches expected (200, 201, etc.)
- Verify: response body shape matches API contract
- Verify: response headers are correct (Content-Type, CORS, caching)
- Record the response time
- Test error cases:
- Missing required fields → expect 400 Bad Request
- Invalid data types → expect 400 or 422
- Missing authentication → expect 401 Unauthorized
- Insufficient permissions → expect 403 Forbidden
- Non-existent resource → expect 404 Not Found
- Verify error response includes helpful message
- Test edge cases:
- Empty strings, null values, zero, negative numbers
- Very long strings (boundary testing)
- Special characters and unicode
- Empty arrays and objects
- Pagination boundaries (page 0, page beyond last)
- Test idempotency (for mutating endpoints):
- Send the same POST/PUT request twice
- Does it create duplicates? (it shouldn't for idempotent operations)
- Does the response change on the second call?
- Report results:
``` ## API Test Results — [ENDPOINT]
| Test | Expected | Actual | Status | |------|----------|--------|--------| | Happy path | 200 | 200 | PASS | | Missing auth | 401 | 401 | PASS | | Invalid body | 400 | 500 | FAIL | | ... | ... | ... | ... |
Response time: Xms Issues found: Y ```
Important
- Use
curlor the project's HTTP client — don't install extra tools. - Don't test against production unless the user explicitly says to.
- Mask sensitive data in output (tokens, passwords, PII).
- Test one endpoint at a time — keep the scope focused.
- Record response times but don't treat them as benchmarks — local testing != production performance.
