Example use cases

Updating token image and description

Technical details
Endpoint
POSThttps://vending-machine.heurist.xyz/x402/metadata/updateWhen to prefer
Use this endpoint when you need to update or enrich the metadata of an already-launched token on the Heurist Vending Machine. This is specifically for post-launch metadata edits (social links, description, image, docs) and requires you to be the token creator. Not for purchasing tokens, launching new tokens, or querying token information.
Side effects

- Invalid or non-existent token contract address — returns error indicating token not found
- Malformed imageUrl or website URL — may return validation error
- Missing required 'token' field — returns 400 bad request
- Payment failure — $1 USDC x402 payment not completed, returns 402 Payment Required
