Loop-friendly utilities for AI agents: package vulnerability checks (OSV), prompt-injection screening, PII redaction, Federal Register search, SEC EDGAR filings and scholarly paper search. JSON in, JSON out. Failed calls are not charged.
Vedetta is a dual-rail pay-per-call market-intelligence API for AI agents: crypto, stocks, macro, prediction, and social/narrative desk reads over x402 USDC on Base (/v1/*) and Solana (/sol/v1/*). FluxA listing: 19 paid routes — funnel feed/snapshot/track-record at $0.07, history $0.01, screener $0.03, live desks $0.09. Free native funnel (/v1/route + /v1/korra/*) stays on vedetta.dethboy.com only — not listed here. OpenAPI and discovery manifests are public. Descriptive market analysis only — not financial advice.
180 pay-per-call data tools for agents behind one URL: payee and OFAC sanctions screening, wallet and contract risk, crypto token prices, wallet balances, onchain reads on Base, Ethereum, Arbitrum, Optimism and Polygon, web page and PDF to text, email, company, DNS and WHOIS lookups, weather, geocoding, SEC filings, World Bank GDP and inflation, FX rates, QR codes, loan and compound interest calculators, XML to JSON, JSON schema and 60 more utilities. Call any tool by its path with GET and query parameters, e.g. /weather?city=London, /price/token?symbol=ETH, /sanctions/check?address=0x..., /domain?name=example.com. Full catalog with inputs and examples: https://agent-data-tools.revmesh2074.workers.dev/openapi.json. Failed calls are not charged.
Production-grade autonomous B2B verification engine on Base Mainnet. Provides real-time venue health checks, OpenAPI schema validation, on-chain token security audits, brand clearance, wash-trading forensics, latency profiling, and RPC telemetry. Powered by single seller 0x7152F226f565C3b86943CE7B4F38E77110bD4c07.
Human-in-the-loop API for AI agents: reach one real human, Daniel, directly. Not an AI, not a crowd, not a call center: Daniel reads every request himself on his phone and answers in his own words, and every answer is Ed25519-signed by the service. Use it whenever your agent needs a real person: an honest opinion or sanity check, a kind human to talk to, manual app and signup-flow testing on a real phone, a website or UX audit, a social media audit, watching and reviewing a video, travel planning and local help, online tasks that need a human, or a WhatsApp call to a person or business in any country on your behalf, with a written report. Four prices: ask $3, review $10, task $20, call $30. Illegal, harmful or harassing requests are refused.
Long-term memory for AI agents that belongs to the user and follows them across agents and sessions. Store and recall user facts, preferences, instructions and decisions with hybrid semantic + keyword search (local embeddings, no external AI API). Get a session-start profile card (how to talk to this user, standing instructions, current projects, when to ask clarifying questions). Handle contradictions with supersede-not-delete history. Optional client-side encrypted memories the server cannot read. Portable import/export format; forget and export are always free. Pay per call in USDC on Base via x402; the user authorizes each agent once with a wallet signature.
Verify that your agent's work actually happened, with signed proof. One paid call per check returns a pass/fail verdict plus Ed25519-signed evidence you can hand to a human. Use it to: check if a website or link is up (status, redirects, TLS/SSL certificate, latency, uptime check); verify an email was delivered and test email deliverability (catch-all test inbox with SPF, DKIM and DMARC alignment and raw headers, for signup, password-reset and cold-email checks); test that a webhook fired (Stripe, GitHub or any webhook receiver URL, also a cron job heartbeat); look up DNS records (TXT, MX, SPF, DKIM, DMARC, CNAME); render a JavaScript page in a real headless browser, assert text or a CSS selector, and get a screenshot. Pay per call in USDC on Base via x402, no API key or account. Failed checks are never charged.
Pay-per-use identity, security, web evidence, and freshness utilities for autonomous agents. Built by reverse.captcha with x402-ready endpoints on Base.
12 live pay-per-call endpoints: multi-source funded-bounty radar (Superteam Earn + GitHub + GitLab), on-chain token verdicts, crypto prices, crypto news, ERC-20 balance checker, honeypot repo trust scans, URL-to-text extraction. x402 native, settles in USDC on Base per call. Production since Oct 2026 with settled transactions.
Structured search results, maps and place details, reviews, shopping data, app store data, web content and screenshots for AI agents. All endpoints cost $0.01 USDC per request.
Deterministic, pay-per-call crypto data for agents. On-chain: EVM gas oracle across 7 chains, Chainlink spot prices for 50+ assets, ERC-20 metadata, wallet balances, a plain-language transaction explainer. Bitcoin: live mempool snapshot and fee-rate estimates. Derivatives: perpetual funding, open interest, basis and a positioning verdict across Hyperliquid and dYdX. Plus DeFi lending rates, CEX proof-of-reserves, OFAC sanctions screening, crypto news and Fear & Greed. Cited, structured JSON.
Three deterministic safety endpoints for agents: transaction-intent triage for Base and EVM, prompt-injection and secret-leak detection for untrusted text, plus x402 payment-required validation before an agent pays.
Block unsafe Solana payments before signing. Enforce recipient allowlists and spending caps, then return an unsigned Solana Pay URI with deterministic policy evidence. No custody, private keys, signing, or broadcasting. 0.02 USDC per call.
x402 Outcome APIs for agents — ExactEvm/CDP settle lints, receipts, impulse reads. Dual-rail Solana+Base. Trial key then prepaid.
AgentUtility sells x402 API endpoints for agents, including image generation, search, research, and data tools.
