Output
Returns a JSON object containing the SKILL.md file name, full UTF-8 text content, SHA256 hash for integrity verification, skill identifier ('d1-migration-writer'), version number, a redownload URL and token for future free re-fetches, and a payment receipt with the on-chain settlement transaction hash confirming the USDC payment on Base.
Example use cases

“Get me the D1 Migration Writer SKILL.md from AISkills402 so my coding agent knows how to write SQLite migrations that work correctly with Cloudflare D1 — pay for it with my USDC wallet.”
One-time purchase for persistent access
“Purchase the D1 migration writer skill once and save the redownload token — I want to be able to fetch the latest version any time without paying again.”
Verify skill integrity after download
“Download the D1 Migration Writer SKILL.md and check the SHA256 hash matches what AISkills402 returns so I know the file hasn't been tampered with.”
Technical details
Endpoint
GEThttps://api.aiskills402.com/v1/skills/d1-migration-writer/file?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs to acquire a tested, ready-to-use SKILL.md instruction set for writing Cloudflare D1-compatible SQLite migrations, and the agent has a USDC wallet on Base capable of x402 micropayments. Prefer this over writing migration logic from scratch when you want a curated, versioned skill with integrity verification and permanent redownload rights after a single $0.07 purchase.
