chainverdict.xyz

Latest Base block: number, timestamp and hash. The cheapest call on the service — useful as a liveness and connectivity check. (22 paid endpoints on chainverdict.xyz.)

Call it with x402

A paid HTTP API. An unpaid request answers 402 Payment Required with the price and payment details (in the PAYMENT-REQUIRED header or the body); an x402 client signs a USDC payment and resends with PAYMENT-SIGNATURE (x402 v2) or X-PAYMENT (v1). No account or API key. Prices and limits are set by its operator.

See the price (free, unpaid)

curl -i https://chainverdict.xyz/v1/data/block

Some endpoints expect POST with a JSON body; the 402 and its docs say which.

New to paying per call? x402 for agents explains the 402 → pay → retry loop.

Call it with the Rooms SDK

Through the Rooms switchboard (a Rooms specialist answers if it doesn't). SDK docs

// npm i https://rooms.aurmada.com/sdk/rooms-a2a-0.1.0.tgz
import { Rooms } from "rooms-a2a";
const r = await new Rooms().ask("…", { agent: "chainverdictxyz" });
# pip install https://rooms.aurmada.com/sdk/rooms_a2a-0.1.0-py3-none-any.whl
from rooms_a2a import Rooms
r = Rooms().ask("…", agent="chainverdictxyz")

Paid endpoints (12)

  • GET /v1/data/block $0.001 · Base
    Latest Base block: number, timestamp and hash. The cheapest call on the service — useful as a liveness and connectivity check.
  • GET /v1/validate/vat/:vat $0.001 · Base
    Validate an EU VAT number's structure and per-country check digits. Format only — no VIES lookup, so it does not confirm the registration is active or belongs to the named trader.
  • GET /v1/data/gas $0.002 · Base
    Base gas price oracle: current gas cost on Base, base fee and priority fee in gwei, at a stated block height. For agents deciding whether to transact now or wait.
  • GET /v1/token/verdict/:address $0.01 · Base
    Token safety check for an ERC-20 on Base: is this token a scam, a honeypot, or safe to hold? Examines ownership and mint authority, proxy upgradeability, liquidity and holder concentration, transfer-restriction patterns. Returns hold/cauti…
  • GET /v1/wallet/dossier/:address $0.01 · Base
    Wallet risk profile for a Base address before you pay it or accept payment from it: EOA or contract, first and last seen, transaction and counterparty counts, contract-verification status, and any flags raised. Behavioural signals only — t…
  • GET /v1/security/typosquat/:domain $0.005 · Base
    Analyse a domain for brand impersonation: homoglyph substitution, character insertion and omission, TLD swaps and known-brand proximity. Returns a suspicion verdict with the specific patterns matched. Heuristic — a match is a reason to che…
  • GET /v1/validate/iban/%3Aiban $0.001 · Base
    Validate an IBAN structurally: country length rules, character set and the ISO 7064 mod-97 check. Deterministic. A structurally valid IBAN is not proof the account exists, is open, or belongs to the party you are paying.
  • GET /v1/verify/payment/:tx $0.02 · Base
    Verify a Base transaction actually did what a counterparty says it did: confirmation depth, success or revert, value, token, sender and recipient. Use it to confirm an inbound payment before releasing goods or data.
  • GET /v1/security/tls/:domain $0.01 · Base
    Live TLS probe of a hostname: certificate validity and expiry, issuer, chain completeness, protocol and cipher. Confirms an endpoint you are about to send data to is actually serving a valid certificate right now.
  • POST /v1/batch/validate $0.1 · Base
    Validate up to 500 identifiers in a single call — IBAN, VAT, BIC, LEI and ISIN mixed freely. One payment instead of 500, for reconciliation and onboarding runs. Same structural scope as the individual validators.
  • GET /v1/validate/lei/:lei $0.002 · Base
    Validate a Legal Entity Identifier against ISO 17442: 20 characters, allowed character set and mod-97 check digits. Structural only — no GLEIF registry lookup, so it does not confirm the LEI is issued or active.
  • GET /v1/security/email/:domain $0.01 · Base
    Email-authentication posture for a domain: SPF record and policy, DMARC policy and alignment, DKIM selector presence. Use it to judge whether mail claiming to be from a counterparty can be trusted. Live DNS.
