How this service works
Reserve-attestation freshness and composition check for a named stablecoin issuer — loud staleness flag when no recent attestation date can be found, reserve composition cited to source where disclosed.
Output
Returns the most recent attestation date for the named stablecoin issuer, a staleness flag if no recent attestation can be found, a breakdown of reserve composition (e.g. Treasuries, cash equivalents, commercial paper), and citations to the source documents where the composition was disclosed.
Example use cases
Verify stablecoin safety before large transfer
“I'm about to move a bunch of USDC to a new wallet. Can you check if Circle has a fresh reserve attestation and what their reserves actually consist of? I want to make sure it's still fully backed.”
Monitor reserve disclosure for portfolio holdings
“I hold several stablecoins in my portfolio — USDT, USDC, and BUSD. Can you pull their latest reserve attestations and flag any that are stale or have changed their composition significantly?”
Assess emerging stablecoin credibility before adoption
“There's a newer stablecoin PYUSD that some platforms are offering. Before I consider using it, can you check if they've published a recent reserve audit and what assets are actually backing it?”
Technical details
Endpoint
GEThttps://stablecoinpulse.theaslangroupllc.com/api/reserve-checkWhen to prefer
Use this endpoint when you need to verify whether a specific stablecoin issuer has published a recent reserve attestation and what assets back their token. Prefer this over generic market dashboards when the core concern is reserve transparency, audit freshness, or detecting undisclosed composition changes for a single named issuer.
Side effects
- Unknown or unsupported issuer name — returns error indicating the issuer is not tracked
- Attestation data unavailable — returns staleness flag with null attestation date
- Source document not publicly accessible — composition returned without full source citation
- Rate limiting or payment failure — 402 or 429 response if payment is insufficient or request quota exceeded
