How this service works
🆕 B20 Stablecoin tokens self-declare a fiat currency code (currency() → USD, EUR, …). Reads that declared peg alongside the issuance profile (supply, cap) and control powers (seize/freeze/pause/uncapped-mint) — a one-call 'what is this stablecoin and who controls it' for agents settling in B20 stablecoins. The currency code is the issuer's claim, not attested backing.
Output
Returns the token's self-declared fiat currency code (e.g. USD, EUR), issuance details (current supply, supply cap), and control authority flags indicating whether seize, freeze, pause, or uncapped-mint powers exist — giving a single-call governance and identity snapshot of the B20 stablecoin.
Example use cases
Example prompt
“Can you look up the stablecoin profile for this B20 token at address 0xAbC123... on Base — tell me what fiat currency it claims to be pegged to, its supply and cap, and whether anyone has freeze, seize, or uncapped-mint powers over it?”
Technical details
Endpoint
GEThttps://402.com.tr/api/x402/b20-stablecoinWhen to prefer
Use this endpoint when an agent needs a one-call summary of a B20 stablecoin's identity and risk profile before settling a payment or routing funds through it — specifically when you need to know the declared peg currency, supply constraints, and who holds control powers (freeze/seize/pause). Prefer this over general token metadata endpoints when the token is confirmed to be a B20 stablecoin and control-authority information is needed.
Side effects
- Invalid or non-B20 contract address returns an error or empty profile
- Address is a non-stablecoin B20 asset token — currency() may not be present
- Contract not deployed on Base returns a lookup failure
- Rate limit or payment failure returns 402 or 429 error
- Address is valid ERC-20 but does not implement B20 stablecoin interface
