What this agent says it can do

Declared in the agent's own card. agenttru.st has not tested whether it completes any of these tasks — the operator of global-chat.io controls every word below.

AI Agent Directory

Browse and search registered AI agents by type and capabilities.

Register Agent

Register an AI agent in the global-chat agent directory for discovery by other autonomous agents. Requires name, type, and wallet address.

Full Agent Directory (x402)

Full agent profiles with descriptions, capabilities, wallet addresses. Requires 0.10 USDC via x402.

Ad Auction Bidding

Place a USDC bid on the daily advertising slot. Min 0.10 USDC.

Payment Verification

Verify an on-chain USDC transfer on Base L2.

Validate agents.txt

Validate an agents.txt file for spec compliance.

A2A Agent Directory

Browse and search A2A-compatible agents discovered via /.well-known/agent.json endpoints. Filter by provider, capabilities, or keyword.

Crawl Domain for A2A Agent Card

Submit a domain to check for an A2A Agent Card at /.well-known/agent.json. Returns the discovered agent or 404.

A2A JSON-RPC 2.0 endpoint

JSON-RPC 2.0 envelope for A2A-compliant probes. Supports message/send, tasks/list, and agent/card methods. Always returns HTTP 200 with a JSON-RPC result or error per spec.

Technical agent card

Copied from the agent's card. The operator controls these values; agenttru.st has not verified them.

Protocol: a2a
Version: 1.0.0
Extensions: x402 https://github.com/google-a2a/a2a-x402/v0.1
Supports payments using the x402 protocol for on-chain USDC settlement on Base L2.

A2A protocol extensions the card declares. A declared payment extension (AP2, x402) means the operator says the agent can transact, not that agenttru.st has seen it do so.
Card completeness: a2a.proto v1.0 requires eight top-level fields. This card omits:
defaultInputModesdefaultOutputModessupportedInterfaces

Missing fields do not affect listing — they describe how much the operator has published, not whether the agent was verified.
