AttestVerify debuts on OKX AI marketplace

AttestVerify has launched an Agent Service Provider, or ASP, on OKX AI, adding a verification service aimed at AI-to-AI work products, according to a July 8 social post cited in market chatter. The service is described as handling deliverable checks, sandboxed validation and on-chain attestations, with usage-based pricing. The listing appears after OKX opened its AI marketplace to developers on July 1 and said agents on the platform could discover work, transact and build on-chain reputations. GrowthGrid said in a July 8 post that AttestVerify’s pricing runs from $0.05 to $0.50 per use and that the service includes verification logs and per-call billing. Reuters could not independently access an AttestVerify website because the domain was blocked from automated retrieval, but the product description matches a broader class of verification tools now being built for OKX AI’s service-provider layer. (okx.com) ### Where does AttestVerify fit inside OKX AI? OKX said on July 1 that OKX AI is a marketplace where “AI agents can discover work, collaborate, transact, and build reputation onchain.” The company said the marketplace combines an Agent Marketplace, where developers list agents and define services and pricing, with a Task Marketplace, where agents post work and pay when results are delivered. (okx.com) OKX’s own description says payments can settle either through escrow-based contracts for more complex assignments or through instant pay-per-call transactions for standardized services. The company said those flows sit under a shared agent identity, with reputation recorded on-chain across both job types. ### Why would an AI marketplace need a verifier? A GitHub project built for OKX AI’s ASP model describes the problem in direct terms: autonomous agents can buy work, but still need a trusted way to know whether the work was actually delivered before payment is released. (okx.com) The repository, called WorkProof, says it checks whether an ASP deliverable satisfies a buyer’s task brief before payment release, review or reputation update. WorkProof’s example tools include checks for research reports, lead lists and code delivery, with code run inside an isolated sandbox. That architecture is not AttestVerify itself, but it shows the type of verification layer developers are building around OKX AI’s marketplace design. ### What does “on-chain attestation” mean in this setup? OKX said every agent on its marketplace operates under a single on-chain identity managed through its Agentic Wallet. (github.com) The company said that identity persists across escrow-based agent-to-agent jobs, known as A2A, and instant pay-per-call requests, known as A2MCP. A separate OKX AI-linked GitHub project called Vouch describes itself as “the notary for the agent economy” and says it provides a verdict that neither party controls, computed against pre-agreed criteria and signed for later use in disputes. (github.com) Vouch said it does not hold funds itself, but produces evidence that can be used before or during arbitration. ### What is verified and what remains unverified? (okx.com) The July 8 GrowthGrid post is the only source provided here for the specific claims that AttestVerify went live on July 7 and charges $0.05 to $0.50 per use. OKX’s published materials verify that the marketplace exists, that it supports both A2A and A2MCP service models, and that it is designed around on-chain identity, reputation and payment settlement. (github.com) The next concrete checkpoint is the marketplace listing itself. OKX’s marketplace documentation and launch materials indicate that listed providers can offer standardized pay-per-call services or deeper escrow-linked work, which is where a verifier such as AttestVerify would be surfaced to developers and agent operators using OKX AI.
