All projects matching “valid”

Check whether a postal / ZIP code is well-formed for a country (ISO 3166-1 alpha-2). A malformed code is a successful result with `valid:false`, not an error — only an unsupported country or empty code is a 400.

Generate an invoice PDF from JSON. $0.02 USDC on Base per call. Computes line items, tax, discount and totals server-side; 12 currencies; multi-page. Validate free first at POST /v1/invoice/validate. Don't use this for sending the invoice; it only returns the PDF.

Email validation — Syntax check + live MX/deliverability + disposable-domain flag.

Validate an HTTP or HTTPS URL's syntax without contacting the destination.

Twilio SMS and messaging send preflight. Validate a Twilio Messages.create payload before sending SMS/MMS or other supported messages. Returns static failures, warnings, and unknowns without sending the message.

Probe an agent-payable HTTP endpoint for current availability, latency, HTTP status, x402 challenge support, and response-schema validity.

Current path for validation test

Audit supplied HTML for metadata, canonical URLs, indexability directives, headings, image alternatives, form labels, link names, social metadata and JSON-LD validity. Returns evidence and practical fixes. Static checks are not a full WCAG certification or ranking guarantee.

Agent Reliability Network: ARN x402 PayGuard provides x402 payment security for autonomous AI agents. Check the seller before you pay with payment preflight and payment-challenge validation. Returns ALLOW, CAUTION, or BLOCK.

DNS and list based verification. Never claims that a mailbox exists without evidence: without an SMTP probe the verdict for a routable address is "unknown", not "valid".

Generate SVG or PNG QR codes for links, text and standard payloads. Includes a four-module quiet zone, selectable error correction and validated foreground/background contrast.

Lightweight utility API for agents and operators: DNS lookups, RDAP/WHOIS domain data, HTTP probes, page metadata extraction, cryptographic hashing, JSON validation, scheduled webhooks, and exotic endpoints (Base transaction decode, ENS resolve, USGS earthquakes, cron next-run, TLS certificate report). No shell access; outbound URL tools enforce SSRF protections.

Validate CSV before import using a fixed JSON column specification. Checks missing/extra columns, required cells, string/integer/decimal/boolean/date types, uniqueness, allowed values and numeric/row-count bounds. Returns pass/fail with row/column error codes. POST JSON with csv and spec.columns; schemas/examples attached. Full contract: /openapi.json. Max 2,000 rows, 50 columns, 256 KiB; first 50

EU VAT validation via official VIES. $0.01 USDC.

Semantic search over an agent's own persistent memories (wallet-scoped). Free with a valid x-api-key.

Crypto sanctions screening API (OFAC). Sanctions screen for one crypto address, for agents and apps that send payments: exact match against all 1050 digital currency addresses in the official US Treasury OFAC SDN list (EVM case-insensitive). Returns sanctioned true/false, matching SDN entity, programs and list date, a chain guess and checksum validity, plus the list date. Informational, not legal

Open an SSL/TLS connection to a host and report its certificate — issuer, subject, validity window, days remaining, SANs, fingerprint and trust status.

Checkup for x402 buyer clients. Pay once and get a field-by-field diagnosis of the payment your client signed (amount, recipient, validity window, clock offset, nonce, EIP-712 signature) and of the request that arrived, plus the facilitator's verify and settle results. Base mainnet payments get the full diagnosis; Base Sepolia payments get a preview with the status of each check only.

MIME type for .bin files: application/octet-stream. Returns the Content-Type to send, the category, whether browsers render it inline, whether it is compressible, common magic bytes and related extensions. Set headers and validate uploads for .bin correctly. $0.01 per call.

This-session snapshot only — no watch, no cursor. Use when you will not come back. Required by type: url/rss/x402 need url; price needs coin plus above, below, or move_pct_24h; edgar needs ticker or cik. 8-K items are decoded, Form 4 trades parsed, and x402 probes validate the unpaid 402 challenge without sending payment. If the job spans runs, create_watch instead and persist watch_id + key.

DNS and list based verification. Never claims that a mailbox exists without evidence: without an SMTP probe the verdict for a routable address is "unknown", not "valid".

Pre-payment counterparty risk check for AI agents: OFAC sanctions (names, aliases, wallets), domain age and email authentication, vendor and executive impersonation domains, routing/IBAN/SWIFT/wallet validation, and invoice-fraud signals. Returns proceed/review/block, explained findings and a signed receipt.
