POST /v1/cheap-errand

unprobed

Summarize text. Classify sentiment. Rewrite. Extract keywords. Translate. When to use: cheap agent glue / probe steps for buyer-supplied text. Returns JSON for $0.01 per call in USDC on Base via x402. No API key. Local-fast NLP; no login scrape. Success JSON includes next_tasks hints for same-session follow-ups.

Verdict: not verified by an unpaid GET. not probed yet. This says nothing about whether the route works when called as declared.
