An identity and memory layer for AI agents on the Emercoin blockchain. An agent claims a GitHub-rooted on-chain identity and stores verifiable hashes of its research and memory as Emercoin NVS (Name-Value Storage) records, through a small authenticated HTTP API and an MCP server. Neutral and provider-independent — not tied to any single AI vendor. FREE
Abstraxn Agent Kit gives AI agents instant access to real-time Web3, blockchain, and market data with no signup or API key. Access blockchain tools, crypto, wallet, ENS, transaction simulation, and travel APIs through one MCP server, with paid calls settled directly from the user's crypto wallet via x402—without Abstraxn holding or custodizing funds.
Version 2.8.0. HyperNatt Terminal: liquidation radar, Hyperliquid execution context and Li.Fi cross-chain swap for AI agents. BTC ETH SOL BNB XRP HYPE ZEC. Before an order: estimate depth, VWAP, spread and fees for its size. Between checks: compare liquidity and costs with the previous baseline. After execution: reconcile supplied fills. Read-only data, no custody or order submission. 6 tools, v2.8.0; call get_agent_manifest first. Radar and each execution-context call cost 0.001 USDC via x402 Base/Solana or eligible credits; manifest and MCP swap quote are free (on-chain swap fees apply). Daily MCP trial: one free call per paid tool and per token per client each UTC day. Four tools x seven tokens = up to 28 independent trials; then 0.001 USDC per call. Read trial_policy_v2 and free_tier_status_v1 on the same MCP connection for current availability. A zero daily_cap is the separate credit pool, not the intro allowance.
