SynapsAI provides an API platform for on-chain verification of claims, images, and documents using AI reasoning and blockchain-backed evidence. Designed as a "Truth-as-a-Service" system, it enables users to submit plain-language claims for AI-driven fact-checking, leveraging live web search and analysis by Claude AI. Each verification process produces a verdict, confidence score, and supporting evidence, all of which are permanently committed to the Sepolia testnet blockchain, ensuring auditable and tamper-evident records.
The platform offers multiple verification pathways. Users can submit content hashes for privacy-preserving or enterprise workflows, or provide full claim text for real-time fact-checking scenarios. In both cases, the system delivers a comprehensive evidence bundle, typically within 15 seconds. SynapsAI also supports counter-evidence submission, allowing any authenticated user to challenge their own claims, while challenging claims from others requires a paid tier. The counter-evidence process involves a three-step AI pipeline—web search, independent evaluation, and synthesis—to compare both sides and commit the result on-chain, with outcomes such as COUNTER_SUPPORTED, COUNTER_CONTRADICTED, or INCONCLUSIVE.
Image forensics are available through a single API call, combining deepfake and AI-generated content detection, error level analysis, metadata validation, and AI-driven consistency checks. The results of these analyses are also written on-chain for independent auditability. Document verification supports both PDF and plain-text formats, extracting text, generating a SHA-256 fingerprint, running AI-content detection, and verifying metadata before recording a tamper-evident hash on the blockchain.
Additional features include a patent-pending trust score system for wallets, based on a time-decay formula, and endpoints for retrieving usage, billing, and verification history. The API supports both public and authenticated endpoints, with rate limits and API key authentication for private actions. Developers can register webhooks to receive HMAC-signed notifications for key verification events, with webhook management available for higher-tier plans. SynapsAI is accessible via REST API endpoints and is currently demonstrated on the Sepolia testnet environment.
In the Other AI space, SynapsAI takes a focused approach. It focuses on automating and securing claim and image verification with AI and blockchain-backed evidence. It is built as a B2B product for developers building trust and verification systems. SynapsAI is a paid product. SynapsAI is available on the command line and API.
SynapsAI first shipped in 2026. PulseGate's similarity index finds few close equivalents — SynapsAI occupies a relatively distinct niche. Key capabilities include claim verification, image forensics, and on-chain proof. It exposes integrations via a public API.
