Readable content is extractable without JavaScript on 2 probed surface(s) with a strong main-content ratio (79% on the homepage).

How this affects the score

These are recorded points before the total is normalized to 100.

When this matters

Crawl-cost estimate

UnscoredObserved
What we found

A manageable sitemap (212 page URLs) helps agents estimate crawl cost.

Why this is unscored

Useful context, outside the readiness score. Adoption, payment support and retrieval cost are not readiness quality by themselves.

When this matters

Measured retrieval path

Tokens, bytes and elapsed time explain retrieval cost and tradeoffs. They are context and do not affect the readiness score.

Static content crawl depth

UnscoredObserved
What we found

Static same-site links led to substantive HTML content two crawl hops from the homepage.

Why this is unscored

Measured, but not yet weighted. It adds no points and its absence subtracts none. Scoring requires calibration of reliability, applicability and overlap with existing checks.

When this matters

Sites with linked public content

Bounded path traversal can explain missing content. Absolute clicks from the homepage is not a validated universal quality scale.

What we found

All 5 agent crawler probes passed. ChatGPT-User=200, ClaudeBot=200, Google-Extended=200, PerplexityBot=200, DeepSeekBot=200

Why this is unscored

A limited scanner observation, not proof of access from real agent infrastructure. It remains unscored until the probe can support that claim.

When this matters

Named client and network context; publisher-permitted retrieval

Current probes identify as HonestClaw with agent-token markers. They cannot verify real vendor access. A bot-protection vendor name alone is not a failure.

A batch/bulk operation is named, but no array request body is declared.

Why this is unscored

Measured, but not yet weighted. It adds no points and its absence subtracts none. Scoring requires calibration of reliability, applicability and overlap with existing checks.

When this matters

Detected interface; pagination only for collections, async only for long-running jobs, batch only for multi-item operations

Usable schemas and operation patterns can reduce ambiguity for clients. More endpoints or constraints alone do not establish that an operation is easier to use.
