IoMarkets.ai verifiable market-truth, paid per request
An agentic, verifiable market-truth oracle on Algorand. Every answer is an
ed25519-signed price proof anchored to a real on-chain USDC micropayment — settled per request via x402.

Rows with a gold edge are the verification tier:
responses carry an ed25519 signature over a canonical payload, anchored to the settlement txid.
Verify a proof yourself — no trust required
Our signing public key is published. Any attestation from the API can be checked offline:
# 1. check the ed25519 signature against the key above
pnpm verify attestation.json # → Signature: VALID
# 2. confirm the printed algorand_txid actually settled on-chain
# https://allo.info/tx/<algorand_txid>
Signature valid and txid settled ⇒ trustworthy, without trusting IoMarkets.ai at all.
Why Algorand & x402
Algorand and x402 solve two halves of the same problem.
x402 is the open, HTTP-native payment standard that lets an autonomous agent pay for a
single request; Algorand is the Layer-1 that settles that payment in ~2 seconds, at a
fraction of a penny, with finality that never reverses. Together they are the rails for machine-payable data — and
IoMarkets.ai is the market-truth oracle built on top.
x402 — the payment protocolAn open, HTTP-native standard (maintained by Coinbase): any request can answer 402 Payment Required and an agent settles a stablecoin micropayment in real time — no accounts, no API keys, no KYC. x402.org →
Algorand — the settlement railWhere each x402 payment actually settles. USDC is native at Layer 1, ~2s finality, zero protocol fees — x402 defines the handshake; Algorand makes it final and irreversible.
IoMarkets.ai — the oracle on topWe sit above both: every priced request returns market data plus an ed25519-signed price proof anchored to its on-chain settlement — verifiable market truth, metered by the call.
Pure Proof-of-StakeValidators are randomly and secretly selected; the chain can't fork, so a processed transaction is permanent.
High throughput, low latencyThousands of transactions per second, settled in under three seconds — built for high-volume DeFi and real-time commerce.
Sub-cent fees≈ $0.000165 per transaction, so deploying contracts and moving assets never means worrying about gas.
Carbon-negativeOne of the greenest chains — carbon-negative, buying offsets directly from a slice of every transaction fee.
Developer-friendlyRobust tooling and standard languages like Python — enterprise-grade apps ship far faster.
Native asset tokenizationBuilt-in, compliant tokenization of real-world assets — real estate, bonds, equities — with no custom code.
Secured for the post-quantum future.FALCON-based State Proofs seal Algorand's history so it stays
verifiable even once quantum computers can break today's signatures. For long-lived, independently-verifiable price proofs,
that future-proofing is a feature you need now — not later.
