How this service works
Paid agent-facing brief on human-execution x402 task payment verification procedure: when an agent hires a human worker through a paid API (Earn Fidotfun style, API for human execution) and must verify the task was actually done by a human before authorizing settlement, plus the refund/dispute path when the delivered result is fake, automated, or missing. Blunt decision procedure, not marketing.
Output
A prose decision-procedure brief (the 'brief' field) written for agents, covering: how to determine if a task was genuinely human-executed, red flags for fake or automated results, and the concrete refund/dispute path to follow when results are invalid or missing. Also returns the topic, generation timestamp, generation source (llm/reasoning/deterministic), and service slug.
Example use cases
Pre-settlement human task verification
“I'm about to pay out a human worker via a crowd-work API for a content moderation task — give me the exact verification steps I should run to confirm a real human did it before I release the USDC.”
Fake result dispute after task delivery
“A human-execution API I hired just returned a result that looks bot-generated — walk me through the refund and dispute procedure so I can claw back the payment before it settles on-chain.”
Earn-style API integration quality gate
“I'm building an agent that hires humans via an Earn-style API and I need a blunt decision gate I can plug in before every settlement to catch missing, automated, or fraudulent task completions.”

Endpoint
GEThttps://k2so.wrong.systems/api/services/human-execution-x402-task-payment-verification-p?utm_source=zero.xyzWhen to prefer
Choose this endpoint when your agent is operating in a human-execution or crowd-work context (e.g. Earn/Fidot-style APIs) and needs a concrete, agent-readable decision procedure for verifying human task completion and handling disputes — not when you need a generic fraud-detection API, smart-contract escrow, or identity verification service.
Side effects
- Payment not provided or rejected — endpoint requires $0.002 USDC via x402 before returning the paid brief
- Invalid or missing 'input' object in request body returns a validation error
- If topic override is malformed the service may default to the canonical topic
- Service may return ok:false with an empty brief if the LLM generation fails
- Rate limiting or provider downtime may return a non-200 response
