"An overview of REST (Representational State Transfer)" matching MCP connectors:
Matching Connector Tools:
Enumerate and inspect PubFi capabilities, then execute an exact selected route.
Neutral fairness computation for agents: two or more parties submit sealed inputs, a published deterministic algorithm runs (fair division, verifiable random selection, Shapley shares), and every party receives an identical signed certificate anyone can re-run and verify for free.
Teardrop is the native economic layer for AI agents, providing a robust suite of tools for multi-chain portfolio tracking, DeFi yield analysis, and gas estimation. It enables autonomous agents to securely find Web3 data and manage micro-payments on-chain with zero human intervention.
Verify VerixID proof-of-existence records and optionally prove ownership.
Durable wallet-addressed memory for AI agents: state that survives your process, opened by your key.
Zero-install remote MCP server for proof-of-existence file attestation.
Keyless prediction-market data across 12 venues plus paper-trading of crypto spot, futures, and PM.
Verify x402 payment endpoints before an AI agent pays: scam scan, on-chain checks, trust scores.
x402 pay-per-call data tools for Base agents. Flagship get_intent ABSTAINS instead of guessing.
Monetization gateway for MCP servers. Agents call a tool, receive an x402 v2 payment challenge, sign a USDC transfer on Base, and get the result. Payment is verified before the tool runs and settled only after it returns, so failed calls are never charged. Discovery and tool listing are free.
Ask what you can't be sure of. Read-only checks on tokens, NFTs, wallets and contracts.
Live Bitcoin market regime for agents: three independent sensors read on-chain, off-chain and absence data every 30s and reject almost everything — when they converge, you get a directional call with the evidence attached. Public track record your agent can audit in one call. MCP + REST + x402. Free tier, no card.
Trust filter for ERC-8004: only ~3.8% of x402 endpoints hit 5+ payers/30d. Free MCP; x402 upgrade.
Trustless escrow & settlement for A2A transactions: exactly-once state machine, frozen fees, tamper-
Blockchain SSN for AI agents. MCP gateway that blocks at the point of action, tamper evident audit.
Screen an Ethereum address or ENS name for on-chain reputation risk, sanctions, and reasoning.
Verify on-chain lifecycle state and provenance of NFC-tagged physical products.
On-chain DEX aggregator quotes, phantom-liquidity scanning, and live proof-of-solvency across Base, Ethereum, Optimism, Arbitrum, and Robinhood Chain. Keyless, no auth.
Celestia knowledge base: CIPs, docs, forum, videos, GitHub, plus live on-chain state
