Schema compliance
tools/list structure, inputSchema validity, and a functional smoke test — the components of the 0-100 score.
- tools/list schema valid
- inputSchema is valid JSON Schema
- Smoke test not run this round
- Cold-start: cold 187ms → warm 177ms (penalty 10ms)
Tools
Tools the server advertised in the latest measurement — measured, not catalog-claimed.
seo_project_listLists every programmatic-SEO project this API key can act on, with id, name, slug, custom domain and page count. Call this FIRST in any session — every other tool needs a projectId from here, and ids cannot be guessed or carried over from another account. FREE — this call costs nothing.
seo_project_createCreates a new programmatic-SEO project and returns its projectId. Call this when seo_project_list comes back empty — every other tool needs a projectId and a new account has none. The project is created EMPTY: it still needs a data source and a content spec before seo_content_generate will run, so call seo_project_get afterwards and read readinessNote. FREE — this call costs nothing.
namestringrequireddomainstringtemplatestring
seo_project_getReturns one project's settings and whether it is configured enough to generate content (needs both a field mapping and a content spec). Use this before seo_content_generate to avoid starting a run that will immediately fail. FREE — this call costs nothing.
projectIdstringrequired
seo_rows_listReturns a page of rows (individual generated pages) with slug, target keyword and status. Statuses are PENDING (no content yet), GENERATING, GENERATED (draft), REVIEWED (approved), PUBLISHED (live), FAILED, FLAGGED_DUPLICATE. Content bodies are NOT included — this is a listing, not an export. Costs 3c per call.
projectIdstringrequiredstatusstringlimitinteger
seo_job_statusReturns the most recent background job for a project: type, status (QUEUED/RUNNING/COMPLETED/FAILED/CANCELLED), progress counters and the last log line. Poll this every few seconds after any tool that starts a job. Do NOT re-call the start tool while status is RUNNING; it will be refused. FREE — this call costs nothing.
projectIdstringrequired
seo_research_startASYNCHRONOUS. Starts a keyword-research run that mines and qualifies keywords into PENDING rows. It spends real AI budget, so call it once and then poll seo_job_status until status is COMPLETED. Returns immediately with a jobId — the keywords do NOT exist yet when this returns. Fails if a research run is already in progress. Costs 750c per call.
projectIdstringrequiredbriefstringrequiredtargetCountinteger
seo_content_generateASYNCHRONOUS. Starts the content-generation queue over every PENDING row in the project. It also spends real AI budget per generated page. Requires the project to be configured (check readyToGenerate via seo_project_get first). Returns a jobId immediately; poll seo_job_status. Generated pages land in GENERATED status and are NOT live until approved and published. Costs 75c per call.
projectIdstringrequired
seo_audit_startASYNCHRONOUS. Scans all generated pages for broken text, unfilled placeholders, truncated copy and missing images, recording findings per page. Returns a jobId; poll seo_job_status. This only REPORTS problems — it does not fix them. Costs 30c per call.
projectIdstringrequired
seo_publishSYNCHRONOUS. Takes approved pages live. IMPORTANT: only rows in REVIEWED status are published — GENERATED drafts are deliberately skipped, because approval is a human gate in this product. The response reports how many were skipped and why; if publishedCount is 0 and skippedNeedsReview is high, the pages need approving in the dashboard first. Costs 15c per call.

Availability history
Each block is one measurement round. Green: working response. Amber: responded but the server was returning errors (5xx). Red: no response at all.
Era history
Each cell is one probe run. Faded cells are incomplete probes — one leg did not answer, so the era is inconclusive.
Response time history
The two probe legs separately: modern server/discover and legacy initialize.
Event log
Derived by comparing consecutive probes — changes in era, protocol version, build and reachability.
