Server-provided instructions

Untrusted server output shown for inspection. It is not Koskamo guidance and is excluded from knowledge search.

Deterministic data tools: Indian identifier validation (GSTIN, PAN, TAN, CIN, LLPIN, IFSC, PIN code, UPI ID, vehicle registration), AI-visibility (GEO) audits, AI crawler robots.txt matrices and llms.txt checks. Each tools/call is paid with x402 (USDC); an unpaid call returns the payment requirements as an error result.

india_id_validate — Validate and decode one Indian identifier
Advertised by the server during the last successful anonymous check.
Advertised read-only

Validates and decodes one Indian business or payment identifier offline: GSTIN, PAN, TAN, CIN, LLPIN, IFSC, PIN code, UPI ID and vehicle registration numbers. Detects the type automatically, normalises copy-paste noise, verifies check digits where the algorithm is public (GSTIN), and decodes embedded fields such as state, PAN holder type or company type. Aadhaar numbers are refused. Use it to clean or pre-check form and invoice data. Price: $0.005 per call, paid with x402.

india_id_validate_batch — Validate up to 50 Indian identifiers
Advertised by the server during the last successful anonymous check.
Advertised read-only

Batch version of the Indian identifier validator: up to 50 values per call (GSTIN, PAN, TAN, CIN, LLPIN, IFSC, PIN code, UPI ID and vehicle registration numbers), mixed types allowed, one flat price. Returns one decoded result per item plus counts by type and validity. Use it for cleaning vendor lists, invoices or onboarding data. Batches containing Aadhaar-like numbers are rejected without charge. Price: $0.02 per call, paid with x402.

geo_audit — AI visibility (GEO) audit for one URL
Advertised by the server during the last successful anonymous check.
Advertised read-onlyOpen-world

Audits how visible one web page is to AI search engines and AI assistants: which of the major AI crawlers robots.txt allows or blocks, llms.txt and llms-full.txt presence, sitemap, and on-page signals (title, meta, canonical, structured data, headings, content readable without JavaScript). Returns a 0-100 score, grade and prioritised recommendations. Use it to check or monitor a site for generative-engine optimisation. Price: $0.02 per call, paid with x402.

ai_crawler_matrix — AI crawler access matrix from robots.txt
Advertised by the server during the last successful anonymous check.
Advertised read-onlyOpen-world

Reads a domain's robots.txt (RFC 9309 matching) and reports, for each known AI crawler and AI agent (OpenAI, Anthropic, Google, Perplexity, Apple, Meta, Amazon, Common Crawl and others), whether it may fetch the site root and up to five extra paths, with the deciding rule and any Content-Signal preferences. Use it to see whether a site is open to AI search but closed to AI training. Price: $0.01 per call, paid with x402.

llms_txt_check — llms.txt presence and structure check
Advertised by the server during the last successful anonymous check.
Advertised read-onlyOpen-world

Checks whether a domain publishes /llms.txt and /llms-full.txt and validates llms.txt against the llmstxt.org structure: single H1 title, blockquote summary, H2 sections with markdown link lists, soft-404 detection and size. Respects robots.txt. Use it before or after publishing an llms.txt file. Price: $0.005 per call, paid with x402.

Connect from your client

Each snippet registers the same endpoint; pick the client you use.

This server is operated by the named third party. Listing and endpoint checks are not an endorsement or a security audit. Review the operator's permissions, terms, and data handling before connecting. How listings are checked and corrected.
