41 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.
Count a text's tokens and estimate the cost of one call on popular LLMs (or the models you list), input plus an expected number of output tokens, and whether it fits each context window.
Breached password check: is this password in known data breaches, and how often? Send only the SHA-1 hash (never the password); just the first 5 characters reach Have I Been Pwned (k-anonymity). Up to 50 hashes per call.
Balance of any ERC-20 token (contract address, or USDC/USDT/DAI by symbol) for a wallet or ENS name on Ethereum, Base, Arbitrum, Optimism or Polygon: raw and decimal-adjusted amount, symbol and decimals; up to 20 tokens...
Resolve ENS (.eth) on Ethereum and Basenames (.base.eth) on Base, forward or reverse. Returns address, name, source, forward_verified, optional avatar.
Trending and newly-listed tokens on DexScreener -- what agents are actually looking at right now, each enriched with its best DEX pair's live price, liquidity, 24h volume, and 24h change. No key. $0.005/call.
Total supply, name, symbol and decimals of an ERC-20 or ERC-721 contract, read on-chain. Use for market-cap math, supply checks and token due diligence.
Token count estimate (plus characters, words, bytes): Estimates how many LLM tokens a text uses with a documented offline heuristic (not an exact tokenizer; typically within about 15% for English), with a low/high range,...
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).
Exact BPE token counts for OpenAI-family encodings (o200k_base for GPT-4o/4.1/5, cl100k_base for GPT-4/3.5/embeddings), single text or batches, with optional truncation to a token budget. Up to 512 KB per call.
UTC time and latest Base block. Use when you need a clock.
Token compression for LLMs
Live and historical crypto token prices (BTC, ETH, SOL, any symbol, CoinGecko id or chain:0x… address) — USDC on Base
Deduplicate facts and near-duplicate notes to save downstream agent tokens
Compress long notes or conversation context into compact operational state for agent handoffs
Run before sending SOL or paying fees, to confirm the wallet really has enough. Never trust a balance remembered from earlier in a chat. Reads a wallet's SOL balance straight from the chain.
Detect language, formality and tone of a text with confidence scores. Deterministic heuristics + compact wordlists. Returns iso_639-1 + register. — $0.001 USDC/call on eip155:8453. Pay-per-call via x402 — no API key, no...
Solana token scout: given a token address, returns live market snapshot (price, liquidity, 24h volume/change) plus mint/freeze authority safety signals.
