How this service works
Robots.txt Policy Writer — Turns a crawler policy written in words into a correct robots.txt, answered as the file only. Knows the mistakes that make a file do the opposite of what was meant - a crawler obeys only the one group that names it, so a GPTBot group silently drops every rule written for the star group and the private paths must be repeated; longest match wins and Allow wins a tie; Google ignores Crawl-delay; Host is a Yandex-only line; Sitemap must be an absolute address; Google-Exte…
Output
Returns a JSON object containing the full SKILL.md file content (UTF-8 encoded), the skill's name ('Robots.txt Policy Writer'), its identifier ('robots-txt-policy'), a SHA256 checksum of the file, the version (e.g. '1.0.0'), a payment receipt with the Base settlement transaction hash and settled status, and a redownload URL and token for future free re-downloads.
Example use cases
Equip agent with robots.txt skill
“I need my AI agent to be able to write proper robots.txt files for websites. Can you buy the robots-txt-policy SKILL.md from AISkills402 over x402 and load it up so the agent knows what to do?”
One-time skill purchase with receipt
“Purchase the robots-txt-policy skill from AISkills402 for me — pay with USDC over x402 — and save the redownload token and the settlement transaction receipt so I have proof of purchase.”
Re-enable agent after environment reset
“My agent lost its skills after a reset. Can you re-download the robots-txt-policy SKILL.md from AISkills402 using the redownload token I have, so it can start writing robots.txt policies again?”
Technical details
Endpoint
GEThttps://api.aiskills402.com/v1/skills/robots-txt-policy/file?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs to acquire the robots.txt policy writing capability as a one-time purchase. It is ideal when the agent environment supports x402 micropayments in USDC on Base, and when you want a tested, versioned SKILL.md file with a permanent redownload token rather than building the skill from scratch. Prefer this over generic prompt engineering when you need a maintained, auditable skill artifact with a cryptographic receipt.
Side effects
- Payment not submitted or insufficient USDC balance — x402 payment required response with payment details
- Invalid or malformed x402 payment header — 402 or 400 error
- Network or API downtime — 5xx server error
- Skill identifier not found — 404 not found
- Redownload token used on wrong endpoint — 404 or unauthorized error
