The tool handles the full payment flow: probe → sign → pay → return response. ### Prerequisites Set EVM_PRIVATE_KEY environment variable with a wallet private key that holds USDC on the target network (e.g., Base Sepolia for testnet). ### Probe an endpoint (check price without paying) x402-cli --json --skip-verify Returns JSON with probe.paymentRequirements containing the price, network, and asset. ### Pay and access an endpoint x402-cli --json -y Returns JSON with payment.body containing the backend response and payment.paymentResponse containing the transaction hash. ### POST with body x402-cli --json -y -X POST -d '{"query": "hello"}' -H 'Content-Type: application/json' ### Self-signed TLS (local development) x402-cli --json -y -k ### Exit codes 0 — Success (payment accepted or probe completed) 1 — Error (network, config, or unexpected failure) 2 — Payment rejected by facilitator 3 — Route is free (no payment needed) ### JSON output structure { "status": "accepted", "probe": { "statusCode": 402, "paymentRequired": true, "paymentRequirements": { "...x402 requirements..." } }, "payment": { "statusCode": 200, "accepted": true, "signer": "0x...", "paymentResponse": { "success": true, "transaction": "0x...", "network": "eip155:84532" }, "body": "...backend response..." } } ### Key fields to parse .status — "free", "payment_required", "accepted", "rejected", "error" .probe.paymentRequirements.accepts[0].amount — price in atomic units .probe.paymentRequirements.accepts[0].network — chain ID (e.g., eip155:84532) .payment.body — the actual backend response after payment .payment.paymentResponse.transaction — on-chain transaction hash ## Trust - Source: tencent - Verification: Indexed source record - Publisher: razvanmacovei - Version: 1.0.3 ## Source health - Status: healthy - Item download looks usable. - Yavira can redirect you to the upstream package for this item. - Health scope: item - Reason: direct_download_ok - Checked at: 2026-05-12T22:48:10.801Z - Expires at: 2026-05-19T22:48:10.801Z - Recommended action: Download for OpenClaw ## Links - [Detail page](https://openagent3.xyz/skills/x402-cli) - [Send to Agent page](https://openagent3.xyz/skills/x402-cli/agent) - [JSON manifest](https://openagent3.xyz/skills/x402-cli/agent.json) - [Markdown brief](https://openagent3.xyz/skills/x402-cli/agent.md) - [Download page](https://openagent3.xyz/downloads/x402-cli)
