Technical details
Endpoint
POSThttps://clonecho.builda.company/x402/s/xkcd-comic?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need structured metadata for a specific xkcd comic by its number — ideal for bots, trivia apps, or enrichment workflows that reference known comic IDs. Prefer over scraping xkcd.com directly, as this returns clean JSON without HTML parsing.
Side effects
- Comic number does not exist — returns an error or empty response
- Missing or invalid num parameter — may return a default or error
- Network or payment failure — 402 payment required if USDC not provided
- Very high comic numbers not yet published — returns not found
