Codecov API
Code coverage reporting and analysis API that aggregates coverage data from CI/CD pipelines and provides REST endpoints for querying coverage reports, commit diffs, and repository settings.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
HTTPS enforced. OAuth via VCS providers. No fine-grained API scopes. SOC2 certified. Note: Codecov experienced a supply chain breach in 2021; current security posture has been overhauled since then.
⚡ Reliability
Best When
Engineering teams already upload coverage to Codecov via CI and want agents to query, gate, or report on coverage data.
Avoid When
You do not have existing CI/CD that uploads coverage reports, or need real-time coverage computation.
Use Cases
- • Querying coverage percentages per commit or pull request for CI/CD gating
- • Monitoring coverage trends across branches and releases
- • Integrating coverage data into agent-generated quality reports
- • Alerting when coverage drops below a threshold after a PR merge
- • Fetching file-level coverage data for detailed analysis
Not For
- • Generating coverage data itself (requires test runners like pytest-cov, Istanbul, etc.)
- • Real-time coverage computation (coverage is uploaded from CI, not computed via API)
- • Teams without CI/CD pipelines that upload coverage reports
Interface
Authentication
Repository tokens for uploading coverage; user tokens for API access. OAuth via GitHub/GitLab/Bitbucket for account authentication. No granular API scopes — token access is all-or-nothing per account.
Pricing
Fully free for open source. Private repo usage requires a paid plan. API access available on all tiers.
Agent Metadata
Known Gotchas
- ⚠ Coverage data may not be available immediately after a CI run — agents should poll with backoff
- ⚠ Rate limits are not publicly documented; agents doing bulk historical queries may get throttled without warning
- ⚠ API responses for commits without coverage data return 404 rather than an empty coverage object
- ⚠ Repository token and user API token are different credentials with different scopes
- ⚠ Codecov is acquired by Sentry — check current docs as API paths and auth may evolve
