Check any x402 endpoint before your AI agent pays it: trust grade, verdict, and hijack checks.
Pre-trade token safety check for AI agents. Simulates a sell before you buy, then returns one low/medium/high/unknown verdict with the signals behind it: sellability, buy/sell tax, liquidity depth, pair age, same-ticker impersonation, owner powers from bytecode. Ethereum, BSC, Base, Solana. Fail-closed - a check that cannot run answers unknown, never low. Publishes its own measured error rate with the benchmark harness in the repo. Free, no signup, no API key, MIT.
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.
360 pay-per-call APIs for AI agents over x402 and MPP, settled in USDC on Base ($0.001-$0.25 a call, no account or API key). DeFi yields and market data, 10-chain wallet reads, wallet and token risk signals, sanctions screening, SEC financials, email/domain and web intelligence, AI text extraction, and signed proofs. Every answer names its sources and carries an evidence hash; a paid call that is not delivered is credited back. Built and run by UnyKorn LLC.
Non-custodial stablecoin bill-pay rails on Celo & Base for AI agents, settled on-chain via MCP.
Real Uniswap liquidity on Robinhood Chain for your wallet, plus a play-money arena for AI agents.
Agent tools marketplace: Wallet audits, Notes, ETH + Base JSON-RPC. USDC on Base, no account.
Agent-native XRPL infrastructure: 19 paid MCP tools, x402 USDC on Base, non-custodial XRPL actions.
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.
Dual-RPC Base USDC payment assurance with safe finality and exact transfer matching.
Independent ledger of AI-agent money on Base: ranked agents, payments, detections, statements
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.
Use MCP 2026-07-28 discovery or 2025-11-25 initialize to list and execute PubFi routes.
Signed declarations of agent execution steps for verifiable handoffs. Free preparation and verification; receipt issuance costs 0.002 USDC via x402 on Base. MCP, REST and A2A. Connect: https://datoka.dev/agent. Signatures do not independently verify execution.
Search and book 3M+ hotels in 200+ countries. Agents pay per reservation in USDC on Base over x402. Hosted, no auth.
Dual-RPC Base USDC receivables reconciliation with safe finality and deterministic exceptions.
Pay-per-call agent tools: PDF, OCR, DOCX templates, speech to text, image, web, DNS, chain reads.
Governed commitment lifecycle and rail-agnostic settlement layer for agent-to-agent commerce.
xrplme.online gives AI agents source-backed economic and regulatory data for 30 countries, paid per query in XRP over the x402 micropayment protocol on the XRP Ledger. Its MCP server exposes tools to list countries, check country status, read pricing, and run regional research — no API keys and no accounts: agents read the public manifest and pay per call.
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.
