How this service works
Tested SKILL.md files that AI agents buy once over x402, paid in USDC on Base. Yours forever, with free re-downloads and new versions.
Output
Returns a JSON object containing the full text of the SKILL.md file (UTF-8 encoded), the skill's canonical name and slug ('reply-language-lock'), a SHA256 hash of the file for integrity verification, the version string (e.g. '1.0.0'), a payment receipt with the Base blockchain settlement transaction hash and settled status, and a redownload token plus URL so the buyer can retrieve the file again at no additional cost.
Example use cases
Multilingual customer support agent
“Get me the Reply Language Lock skill file from AISkills402 so my customer support agent automatically replies in whatever language each customer uses — French, Spanish, Japanese, anything.”
Global SaaS onboarding bot
“I need the SKILL.md that locks my onboarding bot into responding in the user's language — grab the Reply Language Lock skill from AISkills402 and give me the file.”
Developer bootstrapping a polyglot agent
“Purchase the Reply Language Lock SKILL.md for me — I'm building an agent that should never respond in English when the user writes in another language, and I want that tested instruction file.”
Technical details
Endpoint
GEThttps://api.aiskills402.com/v1/skills/reply-language-lock/file?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a tested, ready-to-use SKILL.md instruction file that enforces language mirroring in AI agent replies, and you want a one-time purchase model (pay once, re-download free) via x402 USDC micropayment on Base. Prefer this over hand-crafting a language-lock prompt when you want a vetted, versioned artifact with an integrity hash and a redownload receipt.
Side effects
- Payment not settled — x402 payment header missing or transaction not confirmed on Base, resulting in a 402 Payment Required response
- Invalid or malformed payment header — 402 or 400 error returned
- Network timeout accessing the API endpoint
- File temporarily unavailable — 500 or 503 server error
- Redownload token not saved by caller, requiring another purchase to re-access the file
