Synthdata, Bittensor’s Subnet 50 focused on predictive market intelligence, has integrated its API with x402, Coinbase’s HTTP-based payment protocol, allowing users and agents to purchase real-time financial forecasts directly onchain using stablecoins.
The integration makes Synthdata the first Bittensor subnet to connect with x402. The move enables instant access to forecasts such as BTC, ETH, SOL, and gold price predictions without traditional authentication or third-party intermediaries.
Within hours of launch, the system processed 11 transactions totaling $5.50 in USDC, showing early traction for high-frequency, low-value payments. Thirdweb responded positively to the rollout, saying, “Happy to be working together — excited to push with you all.”
Launched by Coinbase in May 2025, x402 allows payments to be embedded directly into HTTP requests, simplifying settlement and authentication. It uses standard crypto wallet signatures (EIP-712) instead of legacy gateways or complex smart contracts, offering a lightweight solution for automated or programmatic transactions.
With additional API endpoints expected to roll out soon, the integration of Synthdata with x402 marks a major step toward making predictive intelligence and payment infrastructure seamlessly interoperable onchain.
