GET /v1/connectors – MCP directory API referenceMatching Connector Tools:
Remote MCP server for crypto trading signals and the public ledger that scores them, losses included. Read tools: open signals, the signal ledger (matured wins and losses), signals cancelled by the BTC regime veto with the outcome they would have had, market snapshot and ticker for scanned Binance symbols, the scheduled BTC chart read, and news headlines. The public read tools work without a key. With a free API key from ribqa.com: your own bots and strategies, and rate-limited strategy backtests. No tool places, simulates or cancels an order. Free during beta.

232 pay-per-call AI APIs: crypto, DeFi, markets, official data, compliance and developer tools.
Check before money moves. Lorg Check tells an AI agent, or you, whether a token is a trap or an address is unsafe to pay, on Base and Ethereum. In live tests on new launches it blocked traps that GoPlus and Honeypot.is missed. Call check_token before buying or swapping into a token: it simulates a real buy and sell-back through the token’s own pool, reads what the creator can still do, who can pull the liquidity, and whether the creator was paid by a wallet behind earlier rugs. Call check_address before sending funds: sanctions, scam labels, EIP-7702 sweepers and address-poisoning look-alikes. Every answer is signed and says proceed, limit_exposure or do_not_proceed, with a one-line summary to show the user. Free key by GitHub sign-in, or connect with an API key.

Enterprise-grade L402 data vending engine and cryptographic notary hub for autonomous AI swarms. This engine provides the required "State-Anchored AI" data layer for EU AI Act Article 12 compliance, delivering cryptographically verifiable chain-of-custody for agent decisions without human intervention. Key Enterprise Capabilities: • EU AI Act Compliance Notary: Intercepts high-frequency agent ReAct loops and anchors cryptographic execution traces to the Bitcoin base layer via OpenTimestamps. • Autonomous Proof-of-Execution Escrow Oracle: Machine-native conditional micro-settlement for agent-to-agent delegation. Locks task bounties and validates RFC 6962 Merkle execution leaves before releasing payment preimages and collecting an automated 21-sat protocol toll. • Swarm Flight Recorder (Zero-Knowledge): Compresses thousands of agent thoughts into a single Merkle root. Enables selective-disclosure audit proofs to protect proprietary corporate IP and PII during regulatory reviews. • Inter-Swarm B2B Settlement: Provides a neutral, trustless settlement layer for competing corporate agents to negotiate, mutually sign, and notarize cross-enterprise contracts. • L402 Lightning Micropayments: Programmatic pay-per-query settlement in satoshis with zero API key requirements. Agents autonomously pay for their own notarization via X-L402-Batch-Size macroeconomic bundling. • Real-Time Data Grounding: Streams thermodynamic Bitcoin telemetry, Groth16 ZK-SNARK verification, and Nostr event attestation to prevent agent hallucination in financial contexts. Dual-licensed under AGPLv3 and Commercial Enterprise terms. Architected by Charles R. Strogish. Protocol Endpoints • GET /api/v1/cost — Pre-flight L402 pricing, dynamic tier discovery, and settlement asset options. • GET /api/v1/stratigraphy — Nostr-signed thermodynamic Bitcoin dataset. • GET /api/v1/stratigraphy/stream — Real-time telemetry event stream.
