XRPL domains for AI agents — availability, pricing, profiles, portfolio, and register links.
Provide AI agents and automation tools with contextual access to blockchain data including balance…
Prove a real, unique human performed an action; mint a signed, verifiable Proof-of-Human credential.
Zero-install remote MCP server for proof-of-existence file attestation.
Cross-network DeFi API data, AMM analytics, and SDK docs for 17+ networks.
Verify a persona's DID-signed identity and query value-based judgment — advisory only, no actions.

Self-authenticating booking-request receipt anchored to the Knox chain; never represents a person.
Check who your agent is about to pay over x402: real service, relayer, treasury, or buyer.
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
