v0.11.12

Summary

• Propagate the ATXP payment lifecycle id through ATXPAccount retry headers.
• Publish @atxp/client 0.11.12 with the lifecycle header fix.

Validation

• npm test -w packages/atxp-client -- atxpAccountHandler.test.ts
• npm run build -w packages/atxp-client

v0.11.11

What's Changed

• Propagate payment lifecycle IDs through x402 and MPP payment retries.
• Include the lifecycle payment request ID in resource-server settlement and follow-up charge payloads.
• Expose request context helpers for carrying the payment request ID through ATXP server middleware.

This release includes the changes from PR #175.

v0.11.10

Release v0.11.10 with the MPP resource capture changes and release workflow fixes.

v0.11.9

Changes

• Carry destination resource metadata in MPP challenges so accounts can attribute MPP payments to the correct product destination.
• Preserve resource metadata both at the MPP challenge level and inside the serialized request payload for Tempo and Solana MPP challenges.

v0.11.8

• Support for settlement over X402 and MPP in addition to the ATXP protocol.
• Server now issues payment challenges for ATXP+X402+MPP[0][1] combined

[0] MPP challenges over MCP use a non-standard error code (-30402 instead of -32042) for this release for back-compatibility with previous ATXP clients. We intend to drop support for older client versions in a future release to standardize on the -32042 error code. ATXP SDK clients from v0.11.X onwards work with either.

[1] The ATXP server's X402 challenge over MCP uses a custom format and should only be expected to work with the ATXP client.
