ScalpStream Research
Machine-payable, impersonal research feeds over x402: ranked options candidates, dividend/tax-free income, crypto scalp candidates, and best interest-paying cryptos. Built to be polled: free previews carry a judgeable sample and a board fingerprint served as an HTTP ETag, so an agent can detect that the board has changed before deciding to buy, and /schema publishes the JSON Schema of every paid response so a parser can be written first. The full feed settles in XRP/RLUSD (XRPL) or USDC (Base/Arbitrum/Polygon). Not investment advice.

“Crawler Log Triage — AI Crawler Index” is shared by 2 different URLs
All exact-name matches are shown; ranked results follow.-
Paste access-log lines and get back who crawled you. It classifies each line by operator and category, rolls the whole file up by operator with byte and hit counts, finds the lines that are LYING — a user-agent claiming an operator from an address outside every range that operator publishes — and turns the file you actually served into a robots.txt for a stated stance or a WAF ruleset for nginx, caddy, Cloudflare, haproxy or apache. Combined, common, JSON and bare ip+user-agent lines are understood; nothing is fetched and no log is stored. An address outside a published range is reported as unverifiable, which is not the same as fake. Deterministic and read-only: there is no model behind it — every answer comes from a public dataset rebuilt every six hours from each operator's own published documentation and IP ranges, and the same skills are also available as MCP tools at https://www.pathwren.workers.dev/mcp/triage. No key, no signup, no quota. Independent and unaffiliated with any operator it documents.

Devices keep their files; each observation becomes a small signed token (emem:fact: for a signed reading, emem:tree: for one piece of a file: nine token shapes and two addresses in all) that @emem decodes inside ChatGPT, Claude, Salesforce Agentforce, Dify or any MCP client, and that anyone can check offline. emem is free and Apache-2.0; geo.qa runs the same memory in a private tenancy; eudr.dev and propcheck.dev are in testing.

Verify at volume that an address really belongs to the crawler operator it claims. Hand it up to 500 addresses and it says, for each, which operator prefix contains it, from which published source and when that source was last mirrored; hand it a CIDR and it reports every published prefix that contains, is contained by or overlaps it; ask it for an allowlist and it returns a paste-ready nginx, apache, haproxy, Cloudflare, ipset, caddy or plain-CIDR config. It also says which operators can be verified by prefix at all and which need the two-step reverse-DNS check — which it hands you as a command and never runs, because it makes no outbound request of any kind. Absence from a range list is reported as a miss, never as proof of a forgery.
