nlweb-ask-endpoint

nlweb-ask-endpoint is a skill for Claude Code from OrcaQubits/agentic-commerce-skills-plugins. It costs 87 tokens per session (1,903 once invoked), scanned A, original, MIT.

A guide to NLWeb's /ask web endpoint, the HTTP address applications use to send natural-language questions and receive answers. It covers GET and POST requests, structured request data, streaming responses, response messages, and errors.

In plain words
What is it for?
Use it to build an NLWeb question route or a client that calls /ask, handles streaming, and reports errors.
Why use it?
It removes uncertainty about the request and response formats, especially when reading answers as they arrive rather than all at once. It also explains that some status messages are inside the stream, not normal HTTP headers.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

nlweb-ask-endpoint scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

NLWeb /ask Endpoint

Before writing code

Fetch live spec:

  1. Fetch https://github.com/nlweb-ai/NLWeb/blob/main/docs/nlweb-rest-api.md for the canonical /ask contract — request params, response shape, and streaming format.
  2. Fetch https://github.com/nlweb-ai/NLWeb/blob/main/docs/life-of-a-chat-query.md to trace a request end-to-end.
  3. Fetch https://github.com/nlweb-ai/NLWeb/blob/main/docs/nlweb-headers.md for the in-stream "headers" mechanism (license, data-retention, rate-limit messages are NOT HTTP headers).
  4. Web-search the latest release notes for the v0.55+ structured POST body shape (query.text, prefer.mode, prefer.streaming, meta.version) — this is newer than the GET-only legacy contract.
  5. Check webserver/routes/api.py in the live repo to confirm exact param names.

Conceptual Architecture

Routes

Route Method Purpose
/ask GET, POST Main NL query
/who GET Site relevance for a query (federated)
/sites GET List configured sites
/config GET Public config (safe subset)

Request Parameters

Verify exact names against the live routes/api.py. Stable subset:

Param Type Required Default Notes
query string yes NL question
site string no all Backend partition; in MCP can be array
prev string no Comma-separated previous queries (conversation context)
decontextualized_query string no Pre-resolved query; skips server-side decontextualization
streaming bool no true "0" / "false" / "False" disables
query_id string no auto Echoed in response
mode enum no list list | summarize | generate
scorer string no default e.g., nlwebscorer for the neural reranker
itemType string no Schema.org type hint (skip type detection)
response_format string no v0.55 structured-body field

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
