x402 Compute

x402-compute 1.2.0 adds Multi-Provider Payments (MPP) support and updates payment/management flows. - Introduced MPP/Mppx payment options: Users can now provision and manage GPU/VPS with Tempo or Stripe/card (when enabled) in addition to x402 (USDC on Base/Solana). - Updated documentation and quick start to cover MPP usage with `mppx` CLI and environment variable setup for management API keys. - Clarified protocol usage: `X-Payment` for x402, `Authorization: Payment` for MPP. - Added instructions for extending instances via MPP and handling responses with management API keys. - Adjusted wording to reflect support for both x402 and MPP methods throughout workflows and API descriptions.

x402-compute 1.1.0 introduces optional OpenWallet/OWS-based authentication and expands management options. - Added OpenWallet (OWS) support as an optional authentication and agent key management layer. - New script: ows_cli.py for running OWS wallet, sign-message, and key commands. - Auth/environment setup now includes OWS options; direct signing still supported. - Documentation expanded: see references/openwallet-ows.md for OWS usage and details. - No breaking changes to existing direct wallet/private key provisioning or payment flows.

- Updated environment variable documentation for clarity, grouping EVM and Solana payment options under explicit "Option A" and "Option B". - Changed recommended authentication in metadata: now prefers COMPUTE_API_KEY over raw private keys for management. - Updated credential configuration to prioritize API key usage. - No code changes or functionality updates; documentation only.

x402-compute 1.0.6 introduces support for daily instance provisioning and updates workflows for short-duration compute. - Adds support for `--days` flag to provision instances by day, enabling short-term "daily" and "cheaper use-and-throw" compute. - Updates documentation with examples for provisioning and extending instances by days, in addition to by month. - Workflow examples now include provisioning for 1 or 3 days, and extending instances by 1 day or 1 month. - No code or file changes; changelog reflects updated docs and usage patterns only.

x402-compute v1.0.5 Release Date: 2026-02-20 Overview This release adds full Solana payment support to all compute scripts and fixes an authentication issue that caused 401 errors during paid retries. Changes Added - Full Solana payment support for extend_instance.py - The --network solana flag is now fully supported for extend operations - Builds and signs a Solana VersionedTransaction - Uses SPL transferChecked instruction for USDC payments - Automatically creates the recipient USDC token account if it does not exist - Payment flow now matches provision.py Fixed - Fixed 401 Unauthorized errors during paid retry requests - Removed stale compute authentication headers (X-Auth-*) from paid retries - Fix applied to both provision.py and extend_instance.py Removed - Removed all legacy AWAL mode references from extend_instance.py Technical Notes - The 401 issue was caused by nonce reuse - The nonce from the initial 402 response was already recorded by the backend - Re-sending X-Auth-* headers on the paid retry caused authentication failure - The x402 X-Payment header alone is sufficient for authentication - On-chain USDC payment verifies the payer - No additional auth headers are required during the payment step

- Added Solana network support for provisioning and managing compute instances. - Introduced scripts/solana_signing.py for internal Solana x402 payment signing. - Updated environment variables to support Solana keys (SOLANA_SECRET_KEY, SOLANA_WALLET_ADDRESS, COMPUTE_AUTH_CHAIN). - Clarified workflows and script usage for both Base (EVM) and Solana modes. - Removed deprecated AWAL bridge script.

v1.0.3 Changelog: - Bumped x402-compute skill version to 1.0.3. - Added one-time password fallback support docs and script (`get_one_time_password.py`). - Added AWAL support for `provision.py` and `extend_instance.py`. - AWAL mode now requires `COMPUTE_API_KEY` for compute management auth. - Added `awal_bridge.py` helper for AWAL CLI integration. - Improved `provision.py` handling for `201 Created` success responses. - Improved AWAL error messages when `COMPUTE_API_KEY` is missing. - Updated plan-list script to support current API pricing fields. - Updated list/details scripts to show plan and region correctly from API response. - Added SSH-key-first guidance with explicit key generation example (`ssh-keygen ... ~/.ssh/x402_compute`). - Synced skill updates to SGL docs skill folder. - Updated old worker hosted skill manifest/installer to include new script and guidance. - Added compute UI "Password" action in Your Fleet cards with one-time credential modal. - Created external changelog file outside skill folder (as requested).

x402-compute v1.0.2 Changelog Fixed: - Registry metadata fix: Removed X402_USE_AWAL and X402_AUTH_MODE from required env vars(they are optional) - Added credentials.primary: PRIVATE_KEY declaration to properly indicate the primary credential

x402-compute v1.0.1 Fixed: - instance_details.py now displays VPS credentials (root password, IPv6) when available - Previously, the API returned vultr_default_password but the script wasn't showing it - Added a note in the provisioning workflow to clarify that users should wait 2-3 minutes after provisioning for Vultr setup to complete before fetching instance credentials. - No other changes or feature updates included in this version.

x402-compute 1.0.0 – Initial release - Provision and manage GPU/VPS cloud instances with USDC payment on Base or Solana networks via x402 payment protocol. - Supports operations like listing compute plans, provisioning or destroying GPU/VPS servers, extending instance lifetime, and checking status. - CLI scripts provided for browsing plans, provisioning, instance management, and payment handling. - Requires local wallet credentials or integration with Coinbase Agentic Wallet for signing transactions. - Security guidance included for handling private keys and wallet setup. - Detailed environment variable and workflow documentation is provided in SKILL.md.
