The canonical agent card declares NO securitySchemes: the gate on the A2A surface is payment, not identity - an x402 micropayment (EIP-3009 USDC transferWithAuthorization) carried in a PAYMENT-SIGNATURE header per a2a.html, with a 100-requests/day free tier per the pricing document. The MCP surface needed no credential for initialize, tools/list or tools/call and issued no session id. The legacy card at /.well-known/agent.json declares an apiKey scheme in the Authorization header, but no page says how such a key is issued and the canonical card dropped it. No OAuth or OIDC discovery document is served. schemes: - name: anonymous type: none applies_to: ['MCP initialize, tools/list, tools/call', 'GET /a2a/v1', 'GET /a2a/v1/acp/grow, /acp/signals, /acp/oracle', 'POST /a2a/v1 tasks/get and agent/info'] observed: 'HTTP 200 with no credential and no WWW-Authenticate on every call made in this pass (2026-09-19).' - name: x402 type: x402-payment in: header parameter: PAYMENT-SIGNATURE also_allowed_by_cors: [X-Payment, X-402-Payment, X-Payment-Address, X-Payment-Amount, X-Payment-Token, X-Payment-Network] format: EIP-3009 transferWithAuthorization signature for a USDC transfer (CAIP-10 payTo eip155:10143:0x734B0e337bfa7d4764f4B806B4245Dd312DdF134; Base eip155:8453 also listed) purpose: Pay per A2A request (default $0.001 USDC; per-skill prices in the pricing document) beyond the 100/day free tier; unlocks "priority access". scoped: false verified: declared-only - no HTTP 402 challenge was observed; message/send was not exercised sources: [a2a/grokandmon-com-agent-card.json, well-known/grokandmon-com-x402-pricing.json, 'https://grokandmon.com/a2a.html'] - name: apiKey type: apiKey in: header parameter: Authorization purpose: 'Declared only on the legacy /.well-known/agent.json card (securitySchemes.apiKey, security [{apiKey: []}]); absent from the canonical card; no issuance page exists.' issued_at: not published scoped: false sources: [a2a/grokandmon-com-agent-card-legacy.json] discovery: oauth_authorization_server: {url: 'https://grokandmon.com/.well-known/oauth-authorization-server', status: 200, real_document: false, result: spa-shell} oauth_protected_resource: {url: 'https://grokandmon.com/.well-known/oauth-protected-resource', status: 200, real_document: false, result: spa-shell} openid_configuration: {url: 'https://grokandmon.com/.well-known/openid-configuration', status: 200, real_document: false, result: spa-shell}
