On-chain cryptographic price pair attestations for Kaspa applications. Each response carries a price, a timestamp, a signer count, and one signature per attesting node. 13 nodes across three continents poll ten exchange sources and provide a median price.
Every response includes price_numerator and price_denominator — an exact integer ratio, alongside the float, for direct on-chain covenant consumption. Sources that disagree too far from the group are dropped as outliers and counted in outlier_rejected.
A Kaspa covenant checks the attestation's signature when it spends. If the signature is valid, the covenant accepts the price as the contract price — no oracle trust required. Proven on Kaspa mainnet, live today.
Each attestation request specifies a tier. The tier determines how many independent nodes sign the response. Latency is measured, not estimated — n=8 samples per tier, taken live from the public API.
| Tier | Grade | Signers | min | p50 | max |
|---|---|---|---|---|---|
| Free | D | 3 | 47ms | 48ms | 49ms |
| Standard | B | 5 | 63ms | 69ms | 70ms |
| Premium | A+ | 8 | 89ms | 101ms | 123ms |
| Institutional | A+ | 9 | 244ms | 251ms | 433ms |
Each node runs its own Oracle instance, polls exchanges independently, and retains an auditable history. Five percent of paid attestation fees flow into an on-chain reserve pool.
Entry point for all attestation requests. Selects the nearest nodes, enforces tier signer counts, collects signatures, and assembles the signed attestation.
AI agents and LLMs query price data in their native protocol. No REST integration required. Available on Premium and Institutional tiers.
Every node stores its complete attestation history locally. 68,000+ records available. Institutional access on request.
A Kaspa smart contract holds the reserve. Release requires two of three fund signers to agree — no single party can move it alone.
Nine on-chain applications that depend on verifiable price data.
Price swaps at the real market rate. The attestation provides the settlement price.
Borrow against collateral. The covenant liquidates automatically when the oracle reports a threshold breach.
Mint above peg, burn below. The oracle provides the real price; the covenant enforces the rule.
Settle bets on timestamped, signed, verifiable prices. No referee needed.
AI agents read verified prices, decide, and execute. L1 verification. No human in the loop.
Oracle reports a price drop — the policy pays instantly. Verifiably.
Tokenize real-world assets on Kaspa. Each oracle feed anchors the synthetic to the real market.
Auto-convert DAO treasury on price thresholds. Covenant-enforced, no multisig vote needed.
In-game economies priced against real markets — item values, in-game currency exchange rates, tournament payouts, all settled against a real price.

Subscribe: pay in KAS, get your API key automatically — no email, no waiting. The reserve pool is a real smart contract, not a personal wallet — release requires two of three signers.
An autonomous agent can request a single attestation and pay for exactly that one request — no subscription, no account, no human approval step.
