}Latest parsed reserve attestation for one stablecoin issuer as JSON: as_of date, total reserves, composition by asset category, attestor, source_url, current on-chain supply (DefiLlama) and the reserve ratio. Use it when an agent needs machine-readable backing data instead of reading the issuer's PDF. Pass symbol (USDC, USDT, ...) or issuer; period=YYYY-MM selects an earlier month. Issuers without a third-party attestation return supply only with confidence 'none'. Paid: $0.02 per call; without credit you get a PAYMENT_REQUIRED result. Set sample=true for a free example response.
| Argument | Type | Description |
|---|---|---|
| issuer | string | Issuer name or registry id when the symbol is unknown, e.g. "circle" or "paxos" |
| period | string | Report month as YYYY-MM. Default: the newest parsed month. See history_available. |
| sample | boolean | Set true to return an example response at no charge (sample mode). Default false. |
| symbol | string | Token symbol, case-insensitive: USDC, USDT, PYUSD, RLUSD, ... (see stablecoin_list_issuers) |
