How this service works
🆕 The dilution half of B20 rug risk (b20-safety covers seizure). Reads supply cap vs minted supply (how much can still be minted) plus the on-chain SupplyCapUpdated history — an issuer that RAISED the cap diluted, or set up to dilute, holders. Uncapped mint is flagged as the worst case. Pair with b20-control to see who holds the mint role.
Output
Returns the token's supply cap, current minted supply, remaining mintable amount, a flag if the token is uncapped (worst-case dilution risk), and a historical log of SupplyCapUpdated on-chain events showing any past cap increases by the issuer.
Example use cases
Example prompt
“Can you check the supply cap and dilution risk for this B20 token on Base — address 0xAbC123...? I want to know how much more can be minted, and whether the issuer has ever raised the cap.”
Technical details
Endpoint
GEThttps://402.com.tr/api/x402/b20-supplyWhen to prefer
Use this endpoint when evaluating dilution risk for a B20 token — specifically when you need to know whether an issuer can or has inflated supply by raising the cap or having no cap at all. Pair with b20-control to identify who holds the mint role. Prefer this over generic token info endpoints when the B20 standard's SupplyCapUpdated history is needed for rug risk analysis.
Side effects
- Invalid or non-B20 token address returns an error or empty response
- Token contract does not implement supply cap methods — may return null or unsupported error
- Network/RPC issues on Base chain causing timeout
- Address is a valid ERC-20 but not a B20 token, resulting in missing data fields
