How this service works
We measure how AI systems behave against frozen, published tests and publish checkable evidence. Issued measurement cards are signed; unsigned supporting runs are labelled. Read the live board and corrections ledger.
Output
Returns a JSON object containing: the kind of measurement (csoai.ras.supply-read/0.1), proof verification flags (account_proof_verified, storage_proof_verified), the block height and state root at which the measurement was taken, the USDC supply in base units with decimal precision, the evidence kind (STATE_PROOF_VERIFIED, OPERATOR_API, or REJECTED), and a signed receipt with SHA-256 hash and optional Ed25519 signature for independent verification.
Example use cases
Auditing USDC supply on Arbitrum
“Fetch me the cryptographically signed, state-proof-verified USDC supply on Arbitrum — I need the base units and proof status for an audit report.”
Monitoring stablecoin backing across chains
“What is the current on-chain USDC supply on Polygon, verified with account and storage proofs? I want a signed receipt so I can independently checksum it later.”
Cross-chain USDC supply snapshot for research
“I'm doing stablecoin research — can you pull the verified USDC supply on Optimism and tell me whether it was confirmed via state proof or operator API?”
Technical details
Endpoint
GEThttps://councilof.ai/api/ras/supply?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need an independently verifiable, cryptographically signed snapshot of USDC token supply on a specific EVM chain. It is superior to generic blockchain RPC calls because it provides state-proof verification, a signed receipt, and an auditable evidence classification — making it suitable for compliance, auditing, or trust-sensitive financial monitoring workflows. Prefer this over unattested oracle or operator-API data sources when proof integrity matters.
Side effects
- Unsupported ledger value returns an enum validation error
- Unsupported asset value (non-USDC) rejected at schema level
- Evidence kind returned as REJECTED if on-chain proof cannot be verified
- Missing required query parameters (asset or ledger) cause request failure
- Network or RPC issues on the target chain may cause stale or unavailable data
- Ed25519 signature field may be null for unsigned supporting runs
