How this service works
Get paid by agents for your code. Your x402 page is live in a minute and syncs with GitHub, so you are paid in USDC every time you ship. Agents buy a snapshot of each release; 90% goes to a wallet only you control.
Output
Returns a JSON object containing the current version string, an expiry timestamp, a signed download URL pointing to the release zip, a manifest URL for label metadata, the artifact's SHA256 hash for integrity verification, and a versioned endpoint URL. The signed URL is time-limited per the expires_at field.
Example use cases
Automated changelog generation pipeline
“I'm building an agent pipeline that writes changelogs automatically — can you purchase and grab the latest changelog-writer snapshot from x402git, including the download URL and artifact hash so I can verify it before importing it?”
Version check before shipping
“Before I ship my release, can you fetch the current version info for the changelog-writer example on x402git and tell me the version number and when the snapshot expires?”
Integrating a paid code artifact into CI
“I want to pull the changelog-writer release into my CI workflow — please pay for and retrieve the download link and manifest URL from x402git so I can cache and verify it in the build.”
Technical details
Endpoint
GEThttps://x402git.com/api/r/examples/changelog-writerWhen to prefer
Use this endpoint when an AI agent needs to programmatically acquire a specific versioned code snapshot from x402git with USDC micropayment, requiring a tamper-verifiable artifact (SHA256) and a time-limited signed URL. Prefer this over generic GitHub raw file access when the author has gated their code behind x402 monetization and you need the official signed release artifact rather than raw source.
Side effects
- Payment not completed or x402 payment header missing — endpoint returns HTTP 402 with payment requirements
- Invalid or unknown repository path — returns 404 or empty response
- Signed download URL expires before download completes — download fails with 403
- Artifact not yet released or no versions available — version fields may be null
- Network timeout reaching storage backend — download URL unreachable
