Pay-per-call checks an AI agent runs before it moves money or trusts a counterparty. No API keys, no accounts, no signup. Each paid tool call settles in USDC on Base via the x402 protocol, straight from the agent's wallet ($0.001-$0.10 per call), through the Coinbase CDP facilitator, in about two seconds. **Start with the free `payment_info` tool.** It costs nothing, explains how payment works, and lists the price of every other tool. A client without wallet support can still call it. **20 tools in five groups:** - **Free** - `payment_info`: how to pay, what each tool costs, where payments settle. - **On-chain safety** - token safety verdicts (is this ERC-20 a scam, a honeypot, or safe to hold), wallet risk profiles, on-chain payment verification, canonical token checks on Base. - **Finance validators** - IBAN, VAT, BIC/SWIFT, LEI, ISIN: deterministic check-digit and format validation with enrichment. - **Web security** - TLS certificate checks, SPF/DMARC/DKIM email-spoofing posture, brand typosquat and homoglyph detection. - **Base chain data** - live gas oracle, block info, token supply, token activity, address portfolio. Every response carries an evidence record - what was checked, against which sources, how fresh it is, and what the answer does **not** establish - and is Ed25519-signed. **No LLM inference anywhere:** every response is a deterministic computation or a live read of external state, so the same input returns the same answer forever. These are informational signals. None is a compliance control, none discharges a legal obligation, and a valid signature proves a response came from this service unaltered - not that the answer is correct. **Docs:** [llms.txt](https://chainverdict.xyz/llms.txt) - [OpenAPI](https://chainverdict.xyz/openapi.json) - [Methodology](https://chainverdict.xyz/v1/methodology) - [Verify a response](https://pulse.chainverdict.xyz/verify) - [Full portfolio and price list](https://pulse.chainverdict.xyz/.well-known/portfolio.json) - [Website](https://chainverdict.xyz) **Example prompts:** - "What does this cost? Call payment_info." - "Get a token safety verdict for 0x... on Base." - "Profile the wallet 0x... before I pay it." - "Validate this IBAN and this VAT number." - "Is example.com's email spoofable? Check SPF/DMARC."
