Look up a transaction on Base by hash. POST {"hash":"0x..."} and receive its status, block number, from and to addresses, value, gas used and effective gas price. Returns a clear not-found rather than an empty object when the hash is unknown.

Read the head of the Base chain, or a specific block. POST {} for the latest block, or {"number":12345678} for one by height. Returns number, hash, unix timestamp, gas used and transaction count. Useful as an authoritative chain clock.

Ichimoku Cloud signal (tenkan/kijun cross, cloud position, bullish/bearish/neutral) for a crypto pair (top 200 coins) on live candles from Binance.US, Kraken, Gate or MEXC.

Use when a PDF is too large to email, upload or attach — Ghostscript compression an agent sandbox cannot run on its own. Send it either as JSON {pdf_base64} or as the raw PDF body (Content-Type: application/pdf), up to 30 MB. Optional query param mode=light|balanced|max (default balanced). Returns JSON with original_size, compressed_size, reduction_percent, warnings and pdf_base64 (the compressed file).

Confluence trading signal for a crypto pair (top 200 coins): Ichimoku, RSI, MACD, EMA 50/200, Bollinger Bands and volume (OBV) in one call, each with its vote, plus a combined bullish/bearish/neutral signal and confidence. Live candles from Binance.US, Kraken, Gate or MEXC.

Filter up to 25 records against up to 10 yes/no criteria you supply. Each record comes back with keep / review / drop, a reason naming the criterion it failed, a 0-10 score and the per-criterion probabilities. Never drops a record it could not read or could not judge: those come back as review or keep, flagged. Built on a decision model rather than a chat model, so it is a flat per-call price with no token accounting on your side.

IOC feed from Telegram CTI channels. Filters: ip (exact lookup), type(ip|domain|url|md5|sha1|sha256|cve), severity, min_confidence, since, tlp, tag, channel, limit, offset. Returns items[] with iocs[], ttps[], confidence, severity, tlp, tags[].

Server time in several formats at once. POST {} and receive the current UTC instant as ISO-8601, unix seconds, unix milliseconds and RFC-2822. Useful for agents that need an authoritative clock they did not compute themselves.

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 returning silent garbage.

Compute cryptographic digests of a string. POST {"input":"...","algorithms":["sha256"]} and receive one hex digest per requested algorithm. Supports sha256, sha512 and keccak256. Deterministic, no storage, no upstream calls.

Why is my x402 endpoint broken? Diagnose and debug an x402 payment endpoint (or MCP server) when payments fail: checks the 402 challenge, accepts[] (network, payTo, amount, asset), resource URL, Solana settlement readiness, which wallets and agents can pay, Bazaar/OpenAPI discovery and the browser paywall. Returns every check with a fix hint. Read-only: never pays.

Verify a Rubric decision attestation (DAR/0.1): Merkle inclusion proof, HCS anchor ref, service signature status, drift flag. Pass agentId instead for a chain-check continuity report. Not found means no charge. $0.10 either mode.

Deterministic three-service GEO visibility composition with verified procurement accounting.

Current gas conditions on Base. POST {} and receive the legacy gas price and the EIP-1559 base fee of the latest block, in wei and gwei. Useful for agents deciding whether to transact now or wait.

Is this x402 endpoint safe to pay? Check it before your AI agent pays: go / caution / no_go, the recommended payment option, and why (payment would fail, over your budget, price above advertised, not HTTPS, unknown token). Never pays the endpoint. Cached 10 min.

Is this transaction, approval or signature safe to sign? Check it before your AI agent or wallet signs it: pre-sign verdict (green/orange/red + reason codes) for EVM transactions, token approvals and Permit/Permit2/EIP-3009/Seaport signatures. Screens the spender or recipient wallet for OFAC sanctions and scam, phishing or theft reports, and flags unlimited allowances, plain-wallet spenders and risky tokens. Bulk: 100 checks for $0.80 via /v1/credits.

Generate cryptographically random UUIDv4 identifiers. POST {"count":10} and receive that many unique v4 UUIDs, 1 to 100 per call. Uses the platform CSPRNG. No storage.
