Course Drift Oracle

Paid ($0.25). Every drift finding with file path, line number, what is wrong, and the suggested fix - enough to open a PR without re-deriving anything. Verifiable against the free summary's findings_hash.

Paid ($0.25, x402/USDC). Same full drift report as drift_report: every finding with file path, line number, what is wrong, and the suggested fix. Pay with x402 if you hold USDC; use drift_report to pay by card or other MPP methods.

Free. How many pinned models and package versions in the ai-agents-for-beginners course have drifted from upstream reality, broken down by lesson and severity. Returns a signed receipt committing to the full findings set. No payment required.

Free. Look up one model id in the signed catalog: current, deprecated, or retired, plus replacement, earliest_retirement, source, and retrieved. Returns an honest "unknown: not in catalog" for an id this catalog does not track - never conflated with "current". Includes the catalog snapshot's signed receipt.

Paid ($0.10). Look up a list of model ids in the signed catalog and return one entry per id (or an honest "unknown: not in catalog" per id), plus any_action_needed: true if any input model is deprecated or retired. Built for a CI pipeline's pinned-model set - one signed answer and one boolean to gate a build on, instead of parsing an array of free lookups by hand.

Paid ($0.10, x402/USDC). Same batch model status lookup as model_status_batch: one entry per input id plus any_action_needed. Pay with x402 if you hold USDC; use model_status_batch to pay by card or other MPP methods.

Paid ($0.25). All 12 agent-legibility checks for a submitted site URL, each with status and detail, as a dated receipt signed live with a dedicated Ed25519 audit key (or explicitly unsigned while that key is unprovisioned - never a fabricated signature). Verify with verify_report. The signature proves what was checked and when, not that the site is good.

Free. Submit a site URL; the worker runs 12 agent-legibility checks against it (robots.txt AI-crawler directives, llms.txt, MCP advertisement, structured data, meta/charset/content-type sanity, no-JS response) with bounded fetches, private addresses refused, and a per-target rate limit. Returns how many of 12 passed, plus target and date - enough to decide whether the paid per-check detail is worth it.

Paid ($0.25, x402/USDC). Same full site audit as site_audit: all 12 checks with status and detail as a signed dated receipt. Pay with x402 if you hold USDC; use site_audit to pay by card or other MPP methods. Payment settles before the target is checked, so run the free site_audit_summary first to confirm your URL is valid and not rate limited.

Free. Verify a report receipt's Ed25519 signature, and optionally check that a findings array matches the hash the receipt committed to. Use this before paying to confirm the seller is describing real work, and after paying to confirm you received all of it.
