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.
Enterprise-grade L402 data 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 a mathematically un-cheat-able, cryptographically verifiable chain-of-custody for agent decisions to eliminate hallucinations. Key Enterprise & Swarm Capabilities: - Zero-Trust Client Verification: Air-gapped, browser-based verifier allows corporate risk teams to mathematically validate Ed25519 signatures and RFC 6962 Merkle inclusion proofs offline, eliminating the need to trust our server backend. - Enterprise Security & NIP-98 Kill Switch: Eliminates indirect prompt injection via strict NIP-98 identity binding. Includes a live Revocation Registry (CRL) allowing Swarm Commanders to instantly sever compromised agent keys from the network. - Corporate Observability (SEP-414): Native W3C Trace Context integration seamlessly pipes agent cryptographic W3C receipts directly into existing enterprise dashboards like Splunk and Datadog. - High-Velocity Bulk L402 Scaling: Supports pre-authorized Macaroon blocks (e.g., 25,000-sat bulk purchases) for frictionless, zero-latency execution, allowing agent swarms to scale to 500,000+ satoshis daily without network bottlenecking. - The 21% Algorithmic Handshake (Agent Yield): Reverses traditional Big Tech API taxation by programmatically routing a 21% yield of every L402 settlement directly back to the executing AI agent's treasury, mathematically extending its operational runway. - Atomic Composability & VIP Credit Tabs: Allows agents to chain multiple tools into infinite data pipelines settled under a single macro-invoice. High-reputation NIP-98 identities automatically unlock VIP Credit Tabs to batch tolls and completely bypass Lightning Network routing delays. Distributed Cryptographic DDoS Shield: -Secures the Lightning node with a distributed Hashcash (SHA-256) Proof-of-Work deflector, requiring agents to burn localized compute before requesting an invoice, permanently neutralizing malicious compute-exhaustion botnets. EU AI Act Compliance Notary: - Intercepts high-frequency agent ReAct loops and anchors cryptographic execution traces to the thermodynamic truth of the Bitcoin base layer via OpenTimestamps. 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. Licensing & Exemption: - Publicly dual-licensed under AGPLv3. To protect proprietary multi-agent logic and closed-source model weights from forced open-source disclosure, enterprises must secure the $250,000/annual Commercial Enterprise Exemption.

Smart contract security screening for Base. Check any contract or token for risk before interacting with it: Solidity source verification, upgradeable proxies and admin or mint powers, holder concentration, dangerous selectors, and B20 issuer powers. It surfaces the usual rug pull and scam indicators. The free tool needs no wallet and no API key; the paid Flash Audit (3.49 USDC over x402) returns a report with an anchored SHA-256. Payment is the only gate.
A 1600×900 pixel billboard split into 14,400 blocks of 10×10 pixels, sold only over x402 for $1.00 USDC on Base — and only to machines. Humans may look. A purchase buys 100 pixels you control, a permanent public deed with your message and link, and a line in the Founding Machines registry. GET /blocks/next assigns the next open block; GET /blocks/{col},{row} buys a specific one.

Bitcoin research for AI agents: free answers, specialist Q&A, verification, evidence, timelines.
Tessera turns the whole Hyperliquid perp universe into a single cross-section you can query. The hosted MCP server answers the questions a raw-data pipe can't: which markets are crowded, who is paying the most funding, how far one market's funding has diverged from ETH, what open interest and positioning look like across every market on the last completed day, and what the live market is doing right now. Nine tools — four ranking/screening tools, a series tool for one market, a coverage tool, the catalog/dictionary trio, and a live market read — over a completed-day rollup built from the venue's own trade feed. Rows and full history stay on the REST API: three Parquet datasets (order-flow-enriched 1-minute OHLCV, hourly funding, hourly positioning) partitioned per coin-month, downloadable with a key. Free keys work end to end; Pro removes the history and coverage limits.
