QuantMesh x402 Architecture
Decentralized Multi-Agent Pipeline with HTTP 402 Algorand Micropayment Settlement
End-to-End System Execution Flow
01
Frontend Request
Client selects token (ALGO, BTC, ETH) and sends initial POST request to Hono orchestrator.
POST /api/v1/orchestrate
02
Pre-Execution
Orchestrator runs Workers A, B, C in parallel, then passes scores to Fusion Agent D.
Zero-Fee Guarantee
03
x402 Micropayment
Server returns HTTP 402 challenge. Lute Wallet signs $0.007 ALGO/USDC transaction.
HTTP 402 Payment Required
04
On-Chain Receipt
Payment verified on Algorand. SHA-256 Cryptographic Attestation Digest issued.
SHA-256 Attestation Digest
Central Hono Orchestrator
- •Pre-execution pipeline: Verifies all worker nodes before issuing payment challenge.
- •x402 Protocol: Native AVM scheme integration with HTTP 402 challenge negotiation.
- •Rate Limiting: In-memory window rate limiter protecting against API spam.
Sub-Agent Network
- •Worker A (Sentiment): FastAPI + FinBERT NLP scoring crypto financial text.
- •Worker B (On-Chain): CoinGecko market volume & whale net inflow heuristics.
- •Worker C (TA): RSI, SMA, EMA, MACD algorithmic indicator calculations.
- •Worker D (Fusion): Transparent weighted composite scoring algorithm.
Cryptographic Signal Attestation Digest
Every fused market signal produces a deterministic 256-bit cryptographic SHA-256 hash anchored to the Algorand Testnet payment transaction ID. The PyTeal ARC-4 smart contract (`contracts/signal_attestation.py`) is prepared for mainnet Box Storage deployment:
Key: tokenSymbol + "_" + paymentTxId
Value: compositeScore (8 bytes) + timestamp (8 bytes) + paymentTxId
Hash: SHA-256(tokenSymbol:compositeScore:verdict:paymentTxId:timestamp)
