Field	Type	Meaning
`treasury`	string	The treasury address. Open it on Solscan to read the same balance yourself
`treasuryLamports`	string	Its balance, read from Solana at the confirmed commitment during this request
`owedLamports`	string	Credited to recipients, minus payouts confirmed on chain, minus recipient burn orders whose buy has landed
`queuedPayoutsLamports`	string	Payouts waiting in the queue. Already inside owed
`inFlightPayoutsLamports`	string	Payouts signed and sent, not yet confirmed. Already inside owed: one that expires without landing is replaced by a new payout for the same amount
`pendingBurnLamports`	string	Recipient burn orders whose buy has not landed. Already inside owed
`platformAvailableLamports`	string	The platform’s own balance from its ledger. Not owed to anyone, part of the surplus
`surplusLamports`	string	Treasury minus owed. Can be negative, with a leading minus sign
`solvent`	boolean	True when the surplus is zero or more
`checkedAt`	string	When the balance was read

solvent means the treasury covered what it owed at checkedAt. It does not mean the money cannot be moved afterwards. Read what the proof does not prove before relying on it.

Parsing the surplus

surplusLamports is the one lamport field that can be negative. BigInt parses the sign; a parser that only accepts digits will not.

TypeScript

const proof   = await (await fetch("/api/proof")).json();
const surplus = BigInt(proof.surplusLamports);   // may be below 0n
if (!proof.solvent) console.warn("treasury short by", -surplus, "lamports");
