Things to know

  • Caution Payment request is invalid

Flags are plain rules applied to our own checks; they do not change the score. Pro adds the reason behind each flag, every flag, and 90 days of score changes.

Free, and it only reads the endpoint this agent published. To protect other people's servers, each agent is checked live at most once every 10 minutes (clicks in between show the latest result), and each visitor gets 10 checks an hour and 30 a day.

Payments

x402 payment request:
Invalid Last checked 2026-11-05 06:03 UTC.
The agent answered, but its payment request was missing something a buyer needs (who is paid, the token or a readable price). We only ask for the price; we never pay.
Last payment seen:
Not checkable: this agent has not declared a payment address of its own that we can watch.

About this agent

Assay describes itself as a pre-flight security observatory for A2A and MCP endpoints, with a SHA-256 tool schema rug-pull detector, a TDQS compiler, and a verifier for SLA receipts. Its four tools gate remote MCP, A2A, or x402 endpoints before use, register or refresh endpoints, audit paid providers after delivery, and retrieve conformance history and pinned hashes. Developers can reach it through an MCP server and an OpenAPI description listing two operations, including POST /v1/preflight, hosted at assay-207908449630.us-central1.run.app.

This assessment is published by Onchain Agent Intel (onchainagentintel.io), which scores ERC-8004 agents on Ethereum and Base. Registry listings are self-reported. The signals shown here come from public on-chain activity and, where it exists, payment history tied to paid jobs. The full weighted breakdown is returned by the paid /v1/intel endpoint.
