Catch API security vulnerabilities, design anti-patterns, and breaking changes before they reach production. REST and GraphQL supported. Part of our comprehensive security review suite.
Modern apps are API-first, but most code reviews miss API-specific issues. Combine with performance review to catch N+1 queries too.
APIs are the #1 attack vector — 95% of enterprises had an API incident in 2023. OWASP API Top 10 issues cause 90% of breaches. Average cost: $6.1M per breach.
68% of APIs have design inconsistencies. Teams with 100+ endpoints see 3x more integration bugs. Poor API design costs 40 developer hours per month.
Reviewers catch only 25% of API security issues. BOLA vulnerabilities exist in 40% of APIs. Manual review takes 3-5 hours per endpoint.
72% of teams ship breaking API changes unintentionally. Each breaking change costs 8-16 hours of downstream fixes. API downtime costs $5,600 per minute.
Comprehensive API validation across security, design, and documentation
Missing auth checks, BOLA, BFLA, and broken access control
Missing or weak rate limiting that enables abuse
Over-fetching, sensitive data in responses, mass assignment
Missing validation, injection vulnerabilities, type coercion
RESTful violations, inconsistent naming, versioning issues
OpenAPI spec mismatches, undocumented endpoints
Framework-specific validation for both API paradigms
Full REST best practices validation
GraphQL-specific security and performance

"diffray caught a BOLA vulnerability in our payment API that would have exposed customer data. That's a $50k bug bounty we avoided paying."

"Our API design is finally consistent across 50+ endpoints. The AI enforces our style guide better than any human reviewer."

diffray detects authentication vulnerabilities, missing rate limiting, improper error handling, data exposure in responses, inconsistent API design, missing input validation, and OWASP API Top 10 issues.
Yes. diffray reviews both REST and GraphQL APIs, checking for framework-specific issues like N+1 queries in GraphQL, over-fetching, and proper resolver implementation.
API review focuses specifically on API design patterns, authentication flows, rate limiting, versioning, documentation, and API-specific vulnerabilities like BOLA (Broken Object Level Authorization).
Yes. diffray validates that your API implementation matches your OpenAPI specification, catching discrepancies between documented and actual behavior.
BOLA (Broken Object Level Authorization) is the #1 API vulnerability. It occurs when an API endpoint allows users to access resources they shouldn't by manipulating object IDs. diffray detects missing authorization checks that could lead to BOLA.
diffray validates consistent versioning patterns across your API, detects breaking changes in minor versions, and ensures deprecated endpoints are properly marked. It also flags when new endpoints don't follow your established versioning scheme.
