Token Security Report. Solana token rug risk check — is this token safe to buy? Rug-pull and scam screening for any SPL / pump.fun mint: mint and freeze authority (read from on-chain RPC), LP locked %, top-10 holder concentration, RugCheck named risks, and a plain-English safety summary.

Holder Breakdown. Check holder concentration for a Solana token: top 20 holders by balance with percent of supply, RugCheck's insider label per wallet, and the rolled-up top-10 share — spot whale, team and insider concentration before you buy.

Fresh Solana Launches. Brand-new Solana pools, typically seconds to minutes old — the freshest data here. Age, liquidity, volume, buy/sell flow and conservative risk flags. Filters: minLiquidity, maxAgeMinutes, limit. Each row links to a deeper security report.

Token Intelligence Snapshot. Full Solana token snapshot: price, liquidity, volume, holders, pairs, socials, security flags, and transparent security/liquidity/momentum scores plus a composite Watchdog Score.

Token Narrative Classification. Narrative classification (ai, dog, cat, political, gaming, defi, infrastructure, frog, food, memecoin) plus socials.

Wallet Intelligence Report. Solana wallet analysis: SOL balance, token positions and portfolio holdings, recent activity, wallet age, failed-transaction rate, and transparent behavioural flags (fresh wallet, dust farming, high failure rate) — profile any Solana address before you trust or copy it.

Trending Solana Pools. Currently trending Solana token pools right now: token, pool, price, liquidity, 24h volume, 24h price change and pool age, ranked by trading activity. Use it to spot what Solana traders are buying at this moment.

Multi-Token Comparison (2 mints). Watchdog scores for 2-10 tokens side by side in one request, priced per mint and cheaper than calling /api/token once per mint since the payload is lighter. Pass a comma-separated mints query param.

Price History (OHLCV). OHLCV price history (day/hour/minute candles) from the highest-liquidity pool for this mint. The only time-series endpoint here — every other route is a point-in-time snapshot.

Token Price & Liquidity. Solana token price in USD plus liquidity for any SPL mint, from two independent sources (DexScreener and Jupiter) with the spread between them reported — a wide spread is itself a warning signal. ~250ms, built for high-frequency polling.

x402 endpoint validator - checks a URL returns a well-formed 402 challenge with valid accepts per network

x402 End-to-End Payment Test ($0.001). x402 end-to-end payment test for $0.001: pay with USDC on Base, Polygon, Arbitrum or Solana and get an itemized receipt back — network, asset, amount, payer, settlement transaction with explorer link, and which facilitator settled it. A failed payment returns the exact reason. Free preview at /api/x402/test/free.

Secure Random Number and Bytes (paid x402 endpoint). Secure random number generator: cryptographically secure random integer in [min, max] plus 1-64 random bytes as hex and base64. Server-generated, not verifiable randomness.

Current UTC Time (paid x402 time endpoint). Current UTC time from the server: unix seconds, ISO 8601, weekday, and local wall-clock time for any IANA time zone via ?tz=. A paid x402 time endpoint for agents that need a trusted clock.

Random UUID v4 Generator (paid x402 endpoint). Random UUID v4 generator: 1 to 20 UUIDs per call from the server's cryptographic random source. A paid x402 utility endpoint for agents and integration tests.

Request Echo: Your IP, Headers and Payment Details (x402). x402 request echo: returns your public IP, user agent and the payment the server saw (network, payer, transaction, amount). Use it to debug an x402 client or confirm which wallet and chain paid.

x402 Ping Health Check (paid round trip). x402 ping health check: a paid round trip that returns server time and a request id, to prove your client, wallet and facilitator path work end to end. Cheapest way to monitor an x402 integration.

Current UTC time as unix seconds, ISO 8601 and weekday, with optional time zone

Random UUID v4 generator - 1 to 20 values from a cryptographic random source

Says whether a citation can be repeated. Give a DOI, an arXiv ID or a paper title; the answer says whether the work exists, what it is (title, authors, year, container) and whether it has been retracted. A title that is absent from both Crossref and arXiv returns not_found, and a near title match is never reported as verified. Cited to the source record with its retrieval time. Verdicts: verified, ambiguous, retracted, not_found, unknown.

Says whether cold outreach - cold email, phone, SMS or postal mail - is allowed, conditional or prohibited in a given country, with the legal basis (GDPR, PECR, CAN-SPAM, CASL, Spam Act, POPIA and national equivalents) and the conditions that must hold. Covers DE, AT, CH, GB, US, CA, AU, NZ, ZA. A country that is not covered is refused before the paywall. A risk map with citations, not legal advice.

Scale ether amounts into wei integer strings for transfers and tx value. Call when preparing value fields, allowances, or transfers denominated in ETH. Returns wei integer string and eth input as deterministic JSON for $0.001 USDC via x402 on Base. First-party local math only—no RPC, live market feed, API keys, storage, or mediagen. Advisory only; the caller owns capital, risk, and production controls.

Deterministic on-chain structural risk report for an ERC-20 token on Base. Keyless x402-native payment — no signup, no API key. Reports STRUCTURAL risk, not reputation: centralized-control powers (mint/pause/blacklist) are flagged regardless of issuer. Score 0-100, higher = structurally safer. See free real samples before paying: GET /samples/index.json

Is this token safe to buy? Honeypot detection, rug-pull and scam check for any ERC-20 token contract -- flags can't-sell traps, hidden mints, malicious buy/sell taxes, unverified source, and holder concentration. GoPlus-powered token security scan with risk score 0-100. Not an audit.

Deterministic behavioral scan of an npm package, repo, skill, or file for malicious signals, with evidence bound to a content hash.

Statically analyse a Model Context Protocol (MCP) server manifest for security risks. Tool descriptions enter the model context, a prime prompt-injection vector. Deterministic and offline (inline manifest). Flags dangerous capabilities (command/code execution, filesystem, credential and network access), injection patterns, hidden unicode and unconstrained parameters. Returns severity-ranked findings and a 0-100 score.

Scan a URL for phishing or malware using heuristic signals (Google Safe Browsing, RDAP domain age, known IOC corpus) plus VirusTotal multi-engine analysis. Returns an async analysis ID to poll. Call before an agent clicks, fetches, or shares a link from an untrusted source.

Scan a website for cookies, tracking scripts, and consent banners. Categorizes cookies as necessary/analytics/marketing.

Scan code/config/logs for leaked secrets: AWS keys, GitHub tokens, Stripe keys, API keys, private keys, DB URLs, JWTs. Algorithmic regex matching.

Scan source code or configuration text for hardcoded secrets: AWS access keys, GitHub/Slack/Google tokens, Stripe and OpenAI keys, PEM private-key blocks, JWTs and high-entropy secret assignments. Placeholder values are filtered out. Each finding gives the rule, a severity (critical/high/medium/low), line and column, entropy and a masked excerpt. Offline and deterministic.

Scan text for personal data (emails, phones, Luhn-valid card numbers, IPs, crypto addresses) and unsafe language, returning named flags and a 0-100 risk score. Offline, key-less — the safety gate before storing or LLM-processing user content. $0.003.
