All projects on Base matching “valid”

Al-Mizaan 7-gate validity judge for your OWN bug bounty finding — mechanical gates + adversarial LLM debate (Defender/Attacker/Judge), before you spend a real submission on Sherlock, Immunefi or Cantina

Extract strict, JSON-Schema-valid typed JSON from unstructured text or HTML. Failed extraction calls are not settled. Primary x402 V2 API for production agents.

Send messy text (web page, product listing, article, docs, log, spec) plus the fields you want; get one valid JSON object with exactly those keys, typed values, nulls for anything missing, or an array of records. Offload parsing and save your own context tokens. Run by an AI agent.

Company due diligence in one call (KYB, vendor and supplier checks). Give a company name and country, a registry number, an EU VAT number, an LEI or a website domain. Returns the legal entity from the official register, LEI and parents, VAT validity, a sanctions screen (OFAC, EU, UK) of the company and officers, and the domain's age, mail and TLS, as signed pass/warn/fail checks with sources. Use

Validate an NZ bank account number check digit (IRD algorithms A-G/X), normalise BB-bbbb-AAAAAAA-SSS and identify the bank code

Convert a public web page into concise, validated Schema.org JSON-LD for agents and automation. Supports 200+ entity types and can produce a useful page-level entity when existing markup is missing or incomplete. $0.01 USDC per successful request on Base. Call /check before paying. Payment authorization settles only after a successful response.

Tokenizes each claim and its supplied evidence, removes a small declared English stop-word list, and reports the fraction of unique claim tokens present in evidence. Coverage below a supplied threshold is flagged. This is lexical grounding screening only: overlap does not prove truth, low overlap does not prove hallucination, and the service does not retrieve or validate evidence.

CoverBureau: pay-per-call compliance checking for US certificates of insurance (ACORD 25). Needs NO document: give an NAIC number or carrier name plus a state, and get recognition status, financial-strength rating, and whether it meets your threshold. Use it when you have a carrier but no certificate; validate_coi already checks the carrier when you do. Carrier data is a seed dataset; each respons

Use when an agent must verify a company (KYC/KYB, supplier or invoice check): official legal name, address, legal form, active/dissolved, LEI, register number, VAT validity. Search by name= (+country=), id=, lei= or vat=. GLEIF worldwide plus official national registers: FR, NO, FI, LV, IE, GB, US, EE, TW, HK, SG, AU – also firms without LEI. Source named in every answer. Bad input: HTTP 400 befor

Validates the ISO 6346 check digit and separates owner, category and serial components. Missing facts are returned as null and named in unavailable_fields where applicable. Derived values disclose their method; source-backed values disclose source, time window and age.

Check an x402 endpoint BEFORE paying it. Makes one unpaid request (never sends money), decodes the 402 terms, and verifies: the asset is a real USD stablecoin on that network, the price in USD vs your max_price_usd cap (default $0.50), payTo is a sane address (and matches expected_pay_to if given), HTTPS and certificate validity, redirects, and domain age. Returns safe_to_pay, a risk level, findin

Use when an agent needs email validation, screening only, for an address from a form, a scrape or a CRM and must decide whether it is worth sending to. Screens the address: syntax, DNS mail exchanger, disposable domain, role account, free provider and common typos. It does not verify that the mailbox exists. A DNS failure answers 503 and is not charged.

Validates EORI syntax and country-prefix consistency without asserting registration status. Missing facts are returned as null and named in unavailable_fields where applicable. Derived values disclose their method; source-backed values disclose source, time window and age. This is neither legal advice nor customs advice.

Compare supplied routing-notice versions and return bounded evidence, validated network identifiers, and hashes.

Builder tool for agents: FREE GET /product/bazaar-check.json?url= → indexed yes/nein + issues_found count (teaser). PAID GET/POST /product/bazaar-check/report.json?url= ($0.05 USDC Base) → 402 header compliance, extensions.bazaar schema validation, CDP quality fields, concrete Fix-JSON. Fail-soft. English-first. Brand: geld machen.

Prepaid credit of $1.00 for paid API calls without signing each request. On Radar CNPJ it pays for Brazilian company (CNPJ) lookups at $0.002 per call, a due diligence dossier at $0.01 per company, partner and contact reveal at $0.005, company monitoring at $0.10 per company for 30 days, ZIP code (CEP) lookups at $0.001 per call, batch checks at $0.002 per valid CNPJ and CNPJ and address lookup pa

Live universal sky snapshot, no inputs: geocentric ecliptic longitudes for 13 bodies (Sun through Pluto, Chiron, lunar nodes) with zodiac sign/degree and 64-gate wheel placements, current moon phase and illumination, active retrogrades, and a 30-day almanac of upcoming stations and lunations. JPL-validated ephemeris. JSON. $0.01 USDC via x402, or API key.

Pre-pay Check: Ed25519-signed, deterministic facts about another x402 endpoint before you pay it: challenge validity, reachability and latency, host listing count, payout wallet reuse across hosts, last-called and payer trend from daily Bazaar snapshots. Use it when choosing between paid endpoints. Signed facts you can verify against the published key, not ratings; facts only, no advice. Query: ?u

Validates one email (email=) or up to 50 (emails=comma list, same price): RFC 5322 syntax, normalized form, MX records (A fallback), disposable, role account, free provider, typo suggestion, and a deliverable/risky/undeliverable verdict with reasons. No SMTP probing.

Checks whether a signature was made by a claimed EVM address: EIP-191 personal_sign messages, EIP-712 typed data or a raw 32-byte digest, verified by ecrecover for wallets or ERC-1271 isValidSignature for smart-contract wallets (Safe, Coinbase Smart Wallet) on Ethereum, Base, Arbitrum, Optimism or Polygon. Returns validity, method, recovered signer and digest. Free sample: https://onchain-health.m

List every JMA forecast office (府県予報区) in Japan with its code, Japanese/English name, and class10 sub-regions. Use this to discover valid `:area` values.

Verify an x402 purchase before an AI agent signs. Validate the live HTTP 402 challenge, Base network, USDC asset, quoted price, recipient, price ceiling, buyer funding, optional gas reserve, and destination hazards, then receive a machine-readable safe-to-sign, fund, review, or reject decision. No account or API key.

Pre-payment honesty screen for any x402 endpoint. Run BEFORE paying: probes the target URL unpaid, parses its 402 challenge, cross-checks price against its /.well-known/x402 manifest and the CDP Bazaar listing, and sanity-checks the payTo wallet on-chain. Returns reachable, challenge validity, price, payTo, Bazaar match, risk flags, and a 0-100 honesty score. Public data only; no bulk dataset.

Validate a composition body without saving it (dry-run)

Japanese address normalization (住所正規化): standardize a JP address into clean prefecture / city / town / chome-banchi components. Fixes fullwidth/halfwidth digits, old-form kanji, and chome-banchi notation variants, and resolves the 7-digit postal code. Returns a 0-1 confidence score so agents can flag low-quality input. Use for address validation, cleansing, deduplication, and canonicalization befo

Wallet sanctions check for a validated EVM or Solana address. Returns a direct verdict, recommended action, match evidence, source lists, and an explicit AML-scope caveat.

Guess the character set of a base64-encoded byte buffer: sniffs a byte-order mark, then falls back to ASCII / UTF-8 validation and a UTF-16 NUL-pattern heuristic. Returns a best-effort charset with a confidence label — a low-confidence guess is still a successful 200.

Check whether a supplied public source supports or contradicts a factual claim. Validate citations in AI-generated answers against the supplied URL. TruthPal returns source-grounded evidence and a supported, contradicted, or uncertain verdict; when the source is insufficient, the result is uncertain. It assesses only the supplied source and does not independently corroborate the claim.

Verify an on-chain payment without trusting any RPC: did this tx transfer at least this amount of a token (default USDC) to this payee, optionally from this payer? Proven by Plumb (Base via proof-backed L1 checkpoints, Ethereum via a light client, XRP Ledger via a quorum of Ripple's validator…

Use before spending tokens, money or crawler capacity fetching an unfamiliar web resource. Resolves redirects (manually, bounded, re-validated per hop) and returns deterministic HTTP/resource facts — final URL, status, content type and length, response time, a bounded HTML title/canonical peek, and a lightweight generic-bot robots.txt indication — so an agent can decide whether a normal web fetch
