58 services carry this tag in their source record. Tags come from the provider, not from us — a tag is a claim about what the service does, not proof that it does it well.
Decode EVM calldata before signing: function signature candidates (openchain DB), decoded args, and plain-English warnings for approve/setApprovalForAll/permit/unlimited amounts.
Decode JWT: paste a JSON Web Token and get the decoded header, payload claims, human-readable iat/exp/nbf times, expired or not-yet-valid status, seconds until expiry and security warnings such as alg=none. No signature...
skypeek (Tanod) live FAA airport delays: ground stops, ground delay programs, closures, arrival and departure delays at US airports. Not for flight planning. Use when an agent needs live US airport delays, FAA ground sto...
Base32 (RFC 4648) encode or decode text. mode: encode (default) or decode.
Base58 encode or decode text (Bitcoin/IPFS alphabet). mode: encode (default) or decode.
Base64 encode or decode text. mode: encode (default) or decode. Handles URL-safe base64 on decode.
Decode a JWT without verification: header (algorithm), payload claims (subject, issuer, expiration), expiry status, and time remaining. (Decoding only - signatures are NOT verified.)
Decode a barcode or QR code from an image. Send a base64 PNG or JPEG (or a data: URL); returns the decoded text and the symbology. Reads QR, DataMatrix, and 1D barcodes (EAN/UPC/Code39/Code128/ITF/Codabar). Deterministic...
Payment flow verification for agents integrating x402: confirms your wallet and payment channel work before you spend on a real endpoint. Category: infra.
The current time, or a given time, in one or more IANA time zones, with UTC offset, abbreviation, whether daylight saving time is in effect, and the weekday. Give a local time with from_tz to convert it, handling DST cor...
Hex encode or decode text. mode: encode (default) or decode.
Encode text to HTML entities or decode them back. mode: encode (default) or decode.
Decode a Base transaction's calldata into a human-readable function call and arguments — ERC-20 transfer/approve and the EIP-3009 transferWithAuthorization used by x402 settlements. Recognizes x402 settlement transaction...
Check whether a Base transaction settled x402 payments (USDC transferWithAuthorization, EIP-3009): for each, the payer, the payTo address, the amount in USDC, the authorization nonce, the facilitator that sent it, and th...
Convert between unix epoch and human time: pass ?value=<seconds|ms|ISO-string> and get back epoch (s + ms), ISO-8601 UTC, and the value in a target timezone (?tz=America/Santiago, default UTC). Units are auto-detected (1...
Encode or decode base64. POST {"mode":"encode","input":"..."} or {"mode":"decode",...}. Supports standard and url-safe alphabets via {"urlsafe":true}. Decoding validates the input and reports an error rather than returni...
Base64 encode or decode a string.
ABI-encode a function call (selector + args) or encode/decode arbitrary ABI types — build and parse EVM calldata correctly.
UTC time and latest Base block. Use when you need a clock.
Base transaction explained from the chain: success or reverted, block and time, from, to, ETH value, method selector, gas used and fee, contract created, and every ERC-20 transfer decoded with token symbol and amount. In...
Profile of a Base address: wallet (EOA), EIP-7702 delegated wallet or contract; transaction count; ETH and USDC balances; its primary Basename; the token it is, if it is an ERC-20; and the x402 seller it receives payment...
Check whether a phone number is valid and possible, find its country and type (mobile, fixed line, toll free and others), and format it as E.164, international and national (libphonenumber metadata).
Decode a JWT header and payload (signature not verified).
Parse and classify an IPv4/IPv6 address (private, loopback, CGNAT, documentation, ...). Canonical and expanded forms, integer and hex values, version, scope per the IANA special-purpose registries (private, loopback, lin...
