How this service works
OceanEye Sentinel 2.0 — Plataforma de Inteligencia Marítima Satelital con Radar SAR Sentinel-1, Segmentación SAM 3.1 (Puerta A + Control Negativo), Arena Multimodal Muse Wonder 1.0 vs Muse Spark 1.3 (n=30) y Cadena de Custodia Ed25519.
Output
Returns a JSON object containing a boolean 'verified' field indicating proof/constraint validity, the 'check_type' used, the 'solver_mode' applied, and an optional 'counterexample' object (or null) if the verifier found a falsifying assignment.
Example use cases
ZK proof correctness check
“I need to verify a zero-knowledge proof where the expression is `a * b == c`, the witness variables are ['a','b'], the public inputs are ['c'], and I want to run it in zk mode with a 64-bit target bitwidth — can you check if it's valid?”
Bitvec constraint satisfiability
“Check whether this bit-vector constraint is satisfiable in bitvec mode: expression is `x & y == 0`, var bitwidths are x:8 and y:8, target bitwidth 8 — and give me a counterexample if one exists.”
Circuit output variable validation
“Verify my constraint expression `out == in1 ^ in2` in zk mode with witness vars ['in1','in2'], output_var 'out', public inputs ['out'], and target bitwidth 16 — tell me whether it's verified and what solver mode was used.”
Technical details
Endpoint
POSThttps://sentinel.oceaneye-ai.com/x402/verify-zk-and-bitvec?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to verify zero-knowledge proofs or solve bit-vector constraint satisfaction problems via a hosted API, especially when you need a counterexample on failure. Prefer this over local solvers when you want a managed, pay-per-call service with no infrastructure overhead for ZK or SMT-style bit-vector checks.
Side effects
- Invalid expression syntax returns a parse error
- Unsupported bitwidth values may cause solver failure
- Mismatched witness vars and public inputs cause constraint resolution errors
- ZK mode failures when witness values don't satisfy the circuit
- Counterexample returned as null when expression is universally valid but verification fails for other reasons
- Timeout for complex constraint systems with large bitwidths
