x402
Forest Packages – GitHub Release Change Detector is a paid API for AI agents from http--forest-gas-station-mainnet--lcjl27p8lmjs.code.run, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-20).
Fingerprints the normalized metadata state of a public GitHub release and optionally detects changes by comparing against a caller-provided previous SHA-256 hash.

How this service works
Machine-readable contract for active Forest paid capabilities. Unsigned paid calls return HTTP 402 with a PAYMENT-REQUIRED x402 challenge.
Output
Returns a normalized SHA-256 fingerprint of the GitHub release metadata state, and if a previous_hash was provided, indicates whether a material change has occurred between the two snapshots. Does not download assets or inspect repository contents.
Example use cases
CI pipeline release change guard
“Check if the v2.1.0 release of hashicorp/terraform has changed since my last snapshot — compare against hash d4e5f6a7b8c90123d4e5f6a7b8c90123d4e5f6a7b8c90123d4e5f6a7b8c90123 and don't include prereleases.”
Dependency update monitor for automation
“Fingerprint the latest release of facebook/react and tell me if it's changed compared to previous hash 1a2b3c4d5e6f78901a2b3c4d5e6f78901a2b3c4d5e6f78901a2b3c4d5e6f7890, including prerelease versions.”
Security audit release integrity check
“I need to verify whether the v1.9.3 release of pallets/flask has been tampered with or updated — run a fingerprint on it with no previous hash so I get a fresh baseline.”
Technical details
Endpoint
POSThttps://http--forest-gas-station-mainnet--lcjl27p8lmjs.code.run/release/changed?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to detect whether a specific public GitHub release has changed since a previous check, without downloading assets or modifying any state. Ideal for CI/CD pipelines, dependency monitoring agents, or security audits that need lightweight, read-only release integrity verification. Prefer over scraping GitHub directly when you need a normalized, hashable snapshot suitable for programmatic change detection.
Side effects
- Repository not found or is private — returns an error indicating inaccessible repository
- Release identifier not found — returns error when the specified tag or release name does not exist
- Invalid previous_hash format — rejected if hash does not match 64-character hex pattern
- GitHub API rate limiting — may return errors during high-traffic periods
- Malformed repository string (not owner/name format) — validation error
