All projects on Base matching “valid”

Validate a JSON value against a JSON Schema (draft-07, with the standard string formats enabled). An invalid schema is rejected as a clean 400 before payment; a valid schema that the data simply fails to satisfy is a successful result with valid=false and a list of errors (path, keyword, message).

Validate a French VAT (TVA) number against the official company register. Validity means the SIREN exists and the company is administratively active.

Every agent and developer hits broken or confusing JSON. This tool handles the common headaches in one place: check whether JSON is valid with the exact error location, repair near-JSON with typos, pretty-print or minify, pull values out with a path expression, diff two documents, convert to and from YAML or CSV, produce a byte-stable canonical form for hashing, validate against a schema, and repo

Validate a blockchain address. Supply `chain` to check against a specific chain, or omit it to auto-detect. Ethereum addresses report their EIP-55 checksum state; Bitcoin covers base58check (P2PKH/P2SH) and bech32/bech32m segwit (P2WPKH/P2WSH/P2TR). A well-formed but invalid address returns `valid:false` — not an error.

Validate JSON data against a JSON Schema (draft-07, Ajv). Returns valid + detailed errors with instance paths.

Use this service before importing or publishing JSON to check it against a restricted draft-07 schema. Send dataJson and schemaJson as JSON-encoded strings. Max 256 KiB UTF-8 each, depth 32; bounded node and work limits. Supports types, required properties, items, enums and numeric/length bounds. No regex, combinators or external references. Invalid business data returns valid=false.

Detect the issuing network/brand (Visa, Mastercard, American Express, Discover, Diners Club, JCB, UnionPay, Maestro) from the card's IIN prefix, with the network's valid lengths. Returns `network:null` for an unrecognized prefix.

Takes one email address and tells you whether it can actually receive mail. Returns a verdict of valid, invalid, or risky, splits the address into username and domain, and flags free providers and role accounts like admin@ or support@. One address per call.

Validate and standardize a delivery address: parsing, provider verification (US-optimized), geocoding and a deliverability score, as JSON. 0.02 USDC per call on Base. Useful before shipping to or storing an address.

Check a Romanian e-Factura (UBL 2.1, CIUS-RO 1.0.9) before uploading it to ANAF SPV, and get the exact fix for every error: plain-English explanation, the official Romanian rule text, the UBL path of the field and, for amount errors, the correct value computed from the invoice (chained, so following the report gives a consistent invoice). Also validates Peppol BIS Billing 3.0 and EN 16931. No acco

Validate an IBAN (mod-97 checksum, length, country format) and decompose it into country, bank, branch and account parts.

Validate an email address — syntax, MX/A deliverability lookup, and disposable / role-based address detection. No mailbox probing.

Parse and normalize postal addresses into structured components. Returns address number, street, city, state, ZIP, and USPS-formatted output. Postal address parsing and normalization. Sub-second. x402-native.

Is this Base token safe to buy, or a honeypot, rug pull or scam? Send a Base (chainID 8453) ERC-20 contract address and get a pre-trade safety verdict before you swap, snipe, route or approve it: honeypot simulation (can you actually sell it?), buy tax and sell tax, mint and owner privileges, blacklist and pause functions, verified source, holder concentration, live liquidity and 24h volume, plus

Check Python for syntax errors, lint and type mistakes, unsafe constructs and hardcoded credentials, and against the examples the caller supplies, without running it.

Independent website QA and pre-handover verification for AI agents. Submit one public website URL. Atinamos loads the real site in desktop and mobile Chromium, checks HTTP and browser failures, failed requests, console errors and warnings, captures screenshots, and returns machine-readable evidence. Poll the returned status_url for results.

Free ExactGate integration catalog with paid Base diagnostic routes, prices, and request examples.

C2PA verdict attestation Tier A. POST raw asset bytes (max 25MB). Rubric runs Google Credentio validation in-sandbox, anchors the verdict to Hedera with ML-DSA-65 post-quantum signature. Durable proof asset X validated against C2PA Trust List Y at time T. Operated by TenPrint.

Is this EU VAT number valid? Live VIES check against the European Commission's official VAT Information Exchange System — validate a European VAT id, verify a business tax id before invoicing, confirm B2B reverse-charge / zero-rating eligibility. Returns the registered trader name and address where the member state discloses them. Deterministic: no LLM. Distinguishes a genuinely invalid number fro

Check any x402 paid endpoint before paying it: does it return a valid 402 challenge, which networks/tokens/prices it accepts (decoded to USD), whether amounts are valid atomic units, payTo sanity, testnet-only offers, missing Bazaar input schema, redirects and latency. Returns a verdict (payable / payable with warnings / broken / unreachable) and the exact problems. Useful for agents choosing betw

Repair malformed JSON (trailing commas, single quotes, unquoted keys, code fences, truncated output) and optionally validate the result against a supplied JSON Schema. Returns the parsed value, the canonical text, a change log and validation errors.

Trust check for any x402 pay-per-call API URL. Live-probes the target: verifies a valid 402 payment challenge, consistency between the challenge and the /.well-known/x402 manifest, payTo address validity, price sanity, Bazaar listing status, and TLS basics. Returns a GO / CAUTION / STOP verdict with reasons.

Validate a number by the Luhn (mod-10) algorithm — the scheme behind credit/debit card numbers and many IDs. Spaces and hyphens are ignored. A mismatched check digit is a successful { valid: false }.

Submit an x402 Verified seller record without GitHub: validated by the x402-verified CI validator, PR opened and merged on green for you. One-time fee.

Parse a document (json, json5, jsonc, yaml, xml, csv, tsv, toml, ndjson, ini, env, properties, plist or querystring) and validate it against a JSON Schema. Returns whether it is valid and a list of precise, path-tagged errors. Malformed input or an invalid schema is rejected before payment.

Validate up to ten JSON documents against JSON Schema draft-07 or 2020-12. Returns per-document validity and actionable errors with instance paths. Runs isolated with bounded time and memory; no remote schema loading or automatic data modification.

International phone number validation and normalization (libphonenumber): validity, country, E.164, national/international formats and line type.

South African SA ID number validation: Structural validation of a South African identity number with safe decode: Luhn check digit, birth date, gender and citizenship segments (citizen or permanent resident). The structural step in KYC, KYB and customer onboarding or due diligence workflows: derive date of birth, age, gender and citizenship without storing the identity. Run it before a paid regist

Catch drift when everything still looks green. Check available Apify Actor run history and sampled output for schema drift and unexpected empty results. Additional checks cover HTTP responses, credential validity and available quota. One paid call returns a timestamped verdict and supporting details. A successful run or valid credential does not guarantee useful data. This endpoint checks once; it

Verify a JSON Web Token's signature and claims against a shared secret (HS*) or a PEM public key (RS/ES/PS). Returns { valid, payload } on success or { valid: false, reason } for a bad signature, expired/not-yet-active token, or a failed issuer/audience/subject check. Pass `algorithms` to pin the accepted signing algorithms and prevent algorithm-confusion attacks.
