■ Challenge detected

Recomputes every record hash from a canonical JSON representation of id, sequence, timestamp, previous_hash and payload, then checks that each record points to the hash of the record before it. If a root_hash is supplied, the same computed record hashes are folded into a deterministic binary Merkle tree with the last leaf duplicated on odd levels.

POST/webhook-signature$0.002Providers each build their signing string differently — some sign only the body, others prepend a timestamp, an id, or a version marker in a fixed order — and getting that order wrong produces a mismatch that looks exactly like an attack. This checks the signature the way the named provider actually specifies, with constant-time comparison, and returns the string that was signed so a mismatch can be debugged instead of guessed at.
POST/cve-check$0.005Queries OSV.dev for a list of packages with versions across npm, PyPI, Go, Maven, crates.io, NuGet, RubyGems, Packagist and the Linux distributions. For each package it returns the vulnerabilities found with their identifiers, severity and summary, and the single figure that decides what to do next: the lowest version that fixes all of them, derived from the fixed-version events in the affected ranges.
POST/tls-chain$0.002Opens a TLS connection and reports the chain the server presents. Per certificate: subject and issuer, validity window with days remaining, serial, SHA-256 fingerprint, key type and size, and the subject alternative names. Above that it answers the questions a monitor asks: is the requested hostname covered by the leaf certificate including wildcard rules, how many days until the nearest expiry, is any certificate self-signed or signed with a weak algorithm, does the server send its…
