Agent-Tools

agent-tools.nyxlabs.workers.dev · agent-tools.nyxlabs.workers.dev

Audit any x402 or MCP endpoint: fetches it unpaid, decodes the 402 (v1 body and v2 PAYMENT-REQUIRED header), validates scheme/network/asset/payTo/amount/timeout/EIP-712 extra, checks /.well-known/x402.json, /api/health and an MCP initialize call. Returns a JSON report with issues and fixes.

F

Conformance score: 22/100

Catalogue listing, not an A2A agent: a paid API listed by cdp_discovery. Scored on the 3 criteria that apply (9 of 40 points, scaled to 100); the A2A card criteria do not apply.

n/a Agent card n/a

Not applicable: a paid API listed by cdp_discovery. The host serves no A2A agent card at /.well-known/agent-card.json, so the card criteria are not scored.

fail Live endpoint 0/25

No response from the host observed: listed by cdp_discovery only, not confirmed by our own probe.

n/a Protocol version n/a

Not applicable: no A2A agent card served.

n/a JWS signature n/a

Not applicable: no A2A agent card served.

n/a Uptime track record n/a

Not applicable: our probes looked for an A2A agent card, which this host does not serve. That says nothing about the API's availability, so it is not graded.

n/a Skill declaration n/a

Not applicable: no A2A agent card served.

partial Verified Identity 5/10

Provider declared: agent-tools.nyxlabs.workers.dev (https://agent-tools.nyxlabs.workers.dev/). Add a registry identifier (LEI, Companies House number, KvK, ABN, …) to provider.legalEntity for full verified-business credit.
