agent.alexweb.space Deep Verify is a paid API for AI agents from agent.alexweb.space, paid per call via x402, $0.2/call, status unknown (last checked 2026-09-14).
Runs a four-pass independent and adversarial verification pipeline to assess agent-generated outputs against a task and optional hard constraints.

How this service works
Four-pass independent and adversarial verification for high-confidence agent QA.
Output
A structured multi-pass verification report indicating whether the candidate output satisfies the original task, including adversarial critiques from each independent pass, identification of constraint violations, and an overall confidence or pass/fail determination.
Example use cases
Pre-deployment agent output QA
“Before we publish this AI-generated product description, run a thorough four-pass adversarial check — the task was 'write a 100-word product description for our noise-cancelling headphones', here's the candidate text: 'Experience silence like never before…', and the constraints are ['under 110 words', 'no unverifiable claims', 'mention battery life'].”
Automated code review gate
“I need high-confidence verification on this code summary my agent produced — the original task was 'explain what this Python function does', the candidate explanation is 'This function sorts a list in descending order using a quicksort algorithm', and the constraint is ['must be technically accurate', 'reference time complexity'].”
Legal draft compliance check
“Can you do a deep adversarial verify on this contract clause draft? The task was 'draft a liability limitation clause for a SaaS agreement', the candidate clause is 'In no event shall Provider be liable for indirect damages…', and the hard constraints are ['must comply with California law', 'cap must be stated explicitly'].”

Endpoint
POSThttps://agent.alexweb.space/v1/deep-verifyWhen to prefer
Choose this endpoint when you need maximum confidence in an agent's output — especially before high-stakes actions like publishing, deploying, or filing. It is a four-pass adversarial process (vs. the sibling two-pass fast verify), making it slower but significantly more thorough. Prefer it when hard constraints must be enforced, when errors are costly, or when a single-pass review is insufficient for your risk tolerance.
Side effects
- Missing required 'task' or 'candidate' fields returns a 400 error
- Overly long or malformed candidate text may be rejected or truncated
- If constraints are contradictory, the verification may flag all passes as failing without clear resolution
- Network timeouts on very large inputs given the multi-pass latency profile
- Payment failure via x402 protocol blocks the request before processing
