crypto-hash

Endpoints (193 live)

• GET /address/labels — Identify what an EVM address IS in one keyless call: contract/protocol identity (entity, name, category) from Open Labels Initiative attestations with trusted-attester consensus, plus on-chain truth (is_contract, code_hash), reverse ENS/Basename, sanctions (OFAC/UK/EU/UN) and scam-drainer flags. Cited provenance; unknown addresses answer with empty labels, never a 404. (0.02 USDC on Base)
• GET /screen/address — Check whether a crypto address appears on the official public sanctions lists (OFAC SDN, UK, EU, UN). Deterministic exact lookup; returns the matched record (list, program, entity name, reference, currency). (0.003 USDC on Base)
• GET /screen/entity — Fuzzy-screen a person or organization name against the official public sanctions lists (OFAC SDN, UK, EU, UN), including aliases. Returns scored matches with list, program, country, type, and reference. (0.005 USDC on Base)
• GET /wallet/balances — Native-coin balance + ERC-20 token balances (raw + human) for any address on Base, Ethereum, Arbitrum, Optimism, Polygon or BNB (default Base). On Base pass token symbols or 0x addresses (or a default common set); on other networks pass explicit 0x token addresses. (0.005 USDC on Base)
• GET /weather — Current US weather conditions (temp in C+F, humidity, wind, pressure, description) from the NWS for coordinates OR a US address (auto-geocoded). (0.003 USDC on Base)
• POST /crypto/verify — Verify an EIP-191 personal_sign or EIP-712 typed-data signature and recover the signer address from public inputs (message + signature). Verification/recovery only — never signs. (0.003 USDC on Base)
• GET /forecast — Official US weather forecast from the National Weather Service (NOAA): multi-day and hourly periods for any US coordinates or street address. Temperature in Celsius and Fahrenheit, precipitation probability, wind speed and direction, and plain-language conditions. Authoritative government public-domain data, commercial use OK. (0.003 USDC on Base)
• GET /enrich/email — Validate and classify an email DOMAIN from public DNS: MX hosts + mail-provider, SPF and DMARC policy, plus disposable / free-webmail / role-account flags and a deliverability signal. No SMTP probing of individual mailboxes (privacy + ToS). (0.005 USDC on Base)
• GET /geocode — Forward-geocode a street address or place name (WORLDWIDE) to coordinates + parsed address components via OpenStreetMap Nominatim (public, keyless). (0.002 USDC on Base)
• GET /extract — Fetch any public web page and return its main readable content as clean Markdown or plain text plus metadata (title), stripping nav/ads/boilerplate (trafilatura). Optional JS rendering via headless browser for SPAs; markdown or text output. Robots-respecting, public content only — the reader/scraper building block for RAG and agent pipelines. (0.002 USDC on Base)
• GET /crypto/convert — Convert token units (wei/gwei/ether or arbitrary decimals), between hex and int, and compute/validate an EIP-55 checksummed address. (0.001 USDC on Base)
• GET /search — Free-text web search for AI agents: ranked title/url/snippet results fused across multiple engines (Brave, Google, DuckDuckGo, Mojeek, Startpage, Yahoo), with freshness filters (past day/week/month/year), region/locale and SafeSearch. One call for grounded, up-to-date web results — no keys, no scraping setup. (0.003 USDC on Base)
• GET /crypto/hash — Compute keccak256/sha256, a 4-byte function selector, an event topic0, or an ENS namehash/labelhash from a string or hex input. (0.001 USDC on Base)
• POST /tx/raw — Pre-sign safety verdict for a raw EVM transaction. Decodes the calldata against a known-signature registry, shows known-pattern effects (approval delta, transfer target), dry-runs eth_call for revert, checks scam-blocklist and approval-hygiene, and returns allow, warn or block plus a 0-100 risk. Risk indicators, not advice. (0.02 USDC on Base)
• POST /convert — Pure-compute data format conversion (no network): JSON<->CSV, JSON<->YAML, JSON normalize/minify, Markdown->HTML (sanitized), HTML->Markdown/text, base64/hex, TOML->JSON. Operates only on the supplied data. (0.001 USDC on Base)
• POST /quant/risk — Portfolio risk metrics over an array of periodic returns: value-at-risk, conditional VaR, Sharpe, Sortino, max drawdown, Calmar, volatility, and more. Pure computation over your inputs. (0.003 USDC on Base)
• POST /breach/assess — Composite account-takeover risk score (0-100) fusing a privacy-preserving password exposure check with a domain's known breach history. The password is hashed locally (k-anonymity, never transmitted). Returns ato_risk_score, a category, per-signal reasons and the raw signals so the agent can re-rank. Risk indicators, not a guarantee. (0.01 USDC on Base)
• GET /validator/vet — Delegation-risk verdict for a Solana validator from public on-chain data. Give one of vote (vote-account) or identity (node) pubkey and get a verdict of safe, caution, avoid or not_found, a 0-100 risk score, per-dimension flags, reasons and weighted signals across delinquency, commission, commission-rug history, skip-rate percentile, vote-credit performance, agent version lag and superminority concentration. Deterministic, no LLM. Risk indicators, not financial or staking advice. (0.02 USDC on Base)
• POST /crypto/abi — ABI-encode a function call (selector + args) or encode/decode arbitrary ABI types — build and parse EVM calldata correctly. (0.003 USDC on Base)
• POST /breach/password — Check whether a password has appeared in known data breaches, using k-anonymity: the password is hashed locally and only a 5-character hash prefix is sent upstream, so the plaintext is never transmitted, logged or stored. Accepts a password, a SHA-1 hash or an NTLM hash. Returns compromised, breach_count and the hash prefix. Credential-exposure indicators, not a guarantee. (0.003 USDC on Base)
