Check an A2A agent before you delegate, or an MCP server's measured conduct. Free, no key.
Benchmark MCP tool selection with metadata-only routing, collision, abstention, and holdout checks.
Contract-change authorization for AI agents: preflight a change to an API or MCP contract, get a signed decision, and verify the receipt offline. Only a granted change can proceed.
Search Fragments — two tools for the queries an agent can't place, both built to decline rather than guess. resolve_fragment takes a half-remembered, cross-source query ("a musician who became famous for stopping performing") and returns a grounded answer, ranked web sources to confirm by eye, or an explicit no-resolution. verify_claim takes a specific factual assertion and returns supported, partially_supported, insufficient_evidence, or unsupported, with cited evidence and a stated_limits field that is always present. There is no confidence score — insufficient_evidence fires freely, and unsupported requires a source that explicitly contradicts, never mere absence of confirmation. Every verdict is decide-by-eye: "supported" means current web sources confirm it, not that the claim is true. Calibrated against 18 known claims before release. Free, no signup. Streamable HTTP (MCP 2025-11-25). Read-only.
Signed, traced record of what an npm package or file attempts when run, network included. No key.

Agentic Finance: 500+ agent tools, multi-chain USDC over x402 or MPP, or free via proof-of-work
Climate and disaster risk for any place on Earth, from open scientific data. Ask about a city, an address or coordinates and get the 7-day weather risk (heat and cold stress, wind, heavy rain, snow), hazards happening nearby right now (wildfires, earthquakes, floods, cyclones, volcanoes, air quality), long-term climate exposure to 2050 and 2080 (flood depth, sea level rise, extreme heat, drought, water stress) and the country's disaster-risk profile with ~160 benchmarked indicators. Every value cites its source: INFORM, ND-GAIN, World Bank, CMIP6, ERA5, IPCC AR6, WRI Aqueduct, GDACS, NASA FIRMS, OpenAQ, ECCC GDPS. Remote, free, no API key, read-only.
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.

Public chauffeur information, policies and anonymous price previews for Munich and MUC. On explicit customer request, prepare a binding unpaid offer using email OR E.164 phone, without an account. Customers review bound terms and explicitly confirm in Samuelz checkout. The same endpoint provides OAuth-protected booking status, payment review, history, and amendment/cancellation workflows. Booking data and actions require authorized customer access; changes and cancellations require the applicable object-bound consent. Tool discovery is public. Quotes do not guarantee availability, and MCP does not take payment.
Two fact tools free, no key, low limit. Other tools: 14-day trial or paid plan. Watch writes data.
64 individually priced Chinese company data tools at 0.011 USDC per call via remote MCP/x402 on Base; 68 MCP definitions total. Legacy Basic (3 modules, 0.032 USDC) and Full (9 modules, 0.093 USDC) remain separate packages. Additional HTTP x402 products, NOT new MCP tools: Standard screening 0.29 USDC (ten Jinghai checks, JSON plus Chinese/English HTML); Enhanced screening 0.59 USDC (the same ten checks plus exactly one QCC qualifications check); QCC qualifications 0.03 USDC (normalized JSON, up to 30 records, no screening analysis). Product guide: https://yangchunhong3000.github.io/cn-evidence-public-docs/products.html Discovery is free; data queries require a funded Base USDC wallet and explicit x402 spending approval. Plain MCP clients do not pay automatically. Most V3 company tools require company_id from company_detail; record details use record_id from a matching, separately paid parent list. New paged lists return at most five first-page rows; legacy lists at most ten. No automatic pagination, top-up, retry or repayment. Provider balance and service availability apply. Selected records and limited-scope screening only: empty is not no risk; statistics/trends are not detailed records. No complete due diligence, human review, factory verification or supplier-safety guarantee. Native MPP is paused. Internal owner-funded HTTP company-detail, Standard and old QCC v1 samples passed paid delivery/recovery checks. The later QCC v2 funding-policy revision has offline/isolated and unsigned checks, not a fresh funded acceptance. These tests are not customer sales or certification of every tool or MCP client.

Real, bindable home & auto insurance quotes via MCP — actual carrier rates, not estimates. Texas today, expanding across the US. AI agents can check eligibility, run a live multi-carrier quote, compare options (carrier names hidden until bind), and hand the customer a secure link where a licensed agent finalizes coverage — never an automated purchase. No sign-up or API key required; optional free partner keys for integrators.
Scan a site or AI-built app for exposed databases, keys and MCP endpoints, then verify the fixes.
Paid web research, fact-check, page summary and page extraction tools for AI agents. Pay per call in USDC with x402 (Base or Solana). A failed call is not charged.
