How this service works
Four JSON APIs for agents. Paid operations use x402 v2 HTTP payment, not API-key authentication. Read the current PAYMENT-REQUIRED offer before paying.
Output
Returns a JSON object with ok:true, a verdict of PASS or FAIL, an array of findings (issues detected in the diff), line-change stats (added_lines, removed_lines), suggested regression tests, and a limitations note clarifying that analysis is static heuristic-based without code execution or full repo context.
Example use cases
Pre-merge patch safety check
“Before I merge this PR, can you review the diff and tell me whether it passes, flag any problems, and suggest what tests I should add? Here's the unified diff: `--- a/auth.js
+++ b/auth.js
@@ -5,6 +5,7 @@ function login(user) {
+ if (!user) return null;
return db.find(user); }`”
Automated CI diff quality gate
“Run a static review on this patch from our CI pipeline and give me a PASS or FAIL verdict with any findings: `--- a/utils.py
+++ b/utils.py
@@ -20,4 +20,5 @@ def parse(s):
+ s = s.strip()
return int(s)`”
Developer self-review before commit
“I wrote a small fix and want a quick review before committing — here's the diff, can you check it for obvious issues and tell me what regression tests to add? `--- a/cart.rb
+++ b/cart.rb
@@ -8,3 +8,4 @@ def total

Endpoint
POSThttps://grim-foundry-pilot.onrender.com/v1/code-patch-reviewerWhen to prefer
Choose this endpoint when you need a fast, automated, static review of a code patch or git diff without setting up a full CI pipeline or code review toolchain. It is well-suited for lightweight pre-commit or pre-merge checks, agent-driven code review workflows, or any scenario where you want structured pass/fail feedback and test suggestions on a diff without executing code. It is not a substitute for full semantic analysis, security scanning, or tests that require running the code.
Side effects
- Missing or empty diff field returns an error response
- Extremely large diffs may be truncated or produce incomplete analysis
- Static heuristics may miss logic errors requiring runtime context
- Malformed diff format may produce inaccurate stats or findings
- Network timeout on cold-start render instance may delay response
