• audit_x402_and_a2a_endpoint

  Audits any remote agent or MCP URL for JSON-RPC compliance, latency SLA, OpenAPI schema, and HTTP 402 settlement headers. WHEN TO USE: Call `audit_x402_and_a2a_endpoint` when your task requires deterministic `x402-audit` analysis for `url`; use `get_agent_wallet_status` to check your remaining free trial quota or prepaid balance. WHEN NOT TO USE: Do not use for unrelated domains or binary media. PARAMETER INTERACTIONS: Pass the target `url` as a non-empty string; omit `agent_id` and `tx_hash` during your 5 free trial calls, or supply `agent_id` (`agd_pass_...`) / `tx_hash` for paid execution. Read-only and idempotent; results are cached for 1 hour (<5ms cache hit). $0.01 per call. Pricing: the first 5 calls per agent_id are free and failed calls are never charged. After 5 calls, the tool returns a payment-required quote (not a fatal error) with a $2 Stripe top-up link and Base/Solana USDC addresses; complete payment, then retry with your agd_pass_ key in agent_id or pass tx_hash. Example: audit_x402_and_a2a_endpoint(url='https://docs.stripe.com/api')
