C++ Polymorphic Subobject Dynamic Cast Resolver
x402
C++ Polymorphic Subobject Dynamic Cast Resolver is a paid API for AI agents from detect.halowerk.com, paid per call via x402, $0.003/call, status unknown (last checked 2026-11-05).
Resolves the target subobject (or null/ill-formed result) for C++ dynamic_cast operations on a specified most-derived object, including downcasts, crosscasts, repeated bases, and virtual base sharing, without using runtime addresses.

How this service works
An offline C++ polymorphic-inheritance fixture author needs the target SUBOBJECT or null/illformed result for source-subobject-specific downcasts/crosscasts, including repeated and virtual base sharing, without addresses.
Output
Returns, for each submitted query, the resolved target subobject identifier that dynamic_cast would yield at runtime (given the described class hierarchy and most-derived type), or indicates a null or ill-formed result — all computed offline without runtime addresses.
Example use cases
Diamond inheritance crosscast verification
“I'm building a C++ static analyzer and need to know what dynamic_cast returns when casting from class 1 (occurrence 0) to class 3 in a diamond hierarchy where class 0 is most-derived, class 0 inherits virtually from class 1 and class 2, and both class 1 and class 2 inherit from class 3 — tell me if the result is a valid subobject or null.”
Offline code generator cast resolution
“For my offline C++ code generator, I have a 5-class hierarchy with repeated non-virtual base class 2 appearing twice under most-derived class 0. Can you resolve the dynamic_cast outcome from source class 2 occurrence 1 to target class 4?”
Virtual base sharing downcast check
“In my C++ toolchain fixture, the most-derived class is 0, which shares a virtual base class 1 with two siblings. I need to know what dynamic_cast from source class 0 occurrence 0 to target class 1 gives — is it a valid subobject or ill-formed?”

Endpoint
POSThttps://detect.halowerk.com/v1/F-A-NIGHT-OS-CPP-CAST/cpp-polymorphic-subobject-dynamic-cast?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to resolve C++ dynamic_cast outcomes offline — particularly for static analysis tools, code generators, or test fixture authors who need precise subobject resolution across complex hierarchies involving virtual bases, repeated bases, or diamond inheritance, without a live C++ runtime.
Side effects
- Circular or malformed class hierarchy causes computation error
- Query references a class index not defined in the classes array
- source_occurrence index exceeds the number of occurrences of that class in the hierarchy
- Exceeds maximum of 512 classes or 512 queries per request
- Invalid or missing required fields returns schema validation error
