All projects matching “block”

Check an exact npm or PyPI package version immediately before installation using current registry, vulnerability, malicious-package, withdrawal/deprecation, and verified provenance evidence. Returns ALLOW, REVIEW, BLOCK, or UNKNOWN with machine-readable reasons.

Pre-send check for an XRP Ledger payment: whether the destination is activated, requires a destination tag, blocks or pre-approves senders, can hold the token (trust line, limit, freeze, issuer approval), is blackholed, and whether the source can afford it. Returns ok_to_send, send_with_caution, or will_fail with reasons. Useful before any irreversible XRP Ledger payment.

Did this Base payment settle? Status, block, timestamp and confirmations for one transaction hash, with its ERC-20 Transfers decoded (token, from, to, amount; up to 100 listed, transfers_total gives the full count) and any EIP-3009 authorization used, plus match flags for an optional expected payTo and amount, so an x402 PAYMENT-RESPONSE can be checked. Required: hash. $0.002 USDC on Base. Transac

Check an unsigned Solana transaction before signing. Send its base64 serialization; malformed input is rejected before payment. We simulate it on mainnet and return ALLOW, WARN or BLOCK with SOL and token balance changes and reasons, including dangerous approvals, owner changes, excessive outflows and redirected swaps. Solana only. The published sample is synthetic and only shows an HTTP 402 quote

Read-only EVM state API for wallet snapshots, ERC-20 balances, token allowances, contract code, block heights, and bounded eth_call reads across Ethereum, Base, Arbitrum, Optimism, and Polygon. Fixed price: $0.15 USDC on Base for a batch of up to 100 checks. Only submitted checks run. Results are provider-reported RPC data, not cryptographic proofs.

Base network block status reconciled after payment across two pre-probed distinct-operator RPC endpoints

Simulate one unsigned Base transaction before an agent signs it. Runs eth_call and gas estimation on current chain state, decodes the intent (ERC-20 transfer, approve, NFT setApprovalForAll), flags unlimited approvals, calldata sent to a non-contract, zero-address targets, reverts and destination risk labels such as phishing or sanctions. Returns ALLOW, WARN, BLOCK or INCOMPLETE with findings. No

Check Base ERC-20 decimals and total supply at a recorded block, and up to three claims against cited evidence. Returns supported, contradicted, or unknown. Official project coverage currently includes Base USDC only. No safety verdict, liquidity, or holder analysis. One brief costs 0.25 USDC; retain your private Idempotency-Key for recovery.

AI crawler visibility audit: is your website visible to AI crawlers (GPTBot, ClaudeBot, PerplexityBot, OAI-SearchBot) so ChatGPT, Claude and Perplexity can read and cite it? Fetched like an AI crawler, without JavaScript: robots.txt, llms.txt, sitemap, soft 404, JSON-LD, and which crawlers are blocked at the edge. $0.01 per check, one payment per check: every rule, a model verdict, a fix with evid

Smart-contract inspection for any Base token address: which functions exist (mint, pause, blacklist, owner-only), proxy type and admin, verified source, creation block, DEX pool reserves in USD, holder count. Raw facts with sources and timestamps. Information, not investment advice.

Fetch one public HTTP(S) URL for research, extraction, or agent workflows. Returns the final URL, upstream status, content type, and decoded content. Private, local, metadata, and reserved destinations are blocked; redirects are revalidated and response size and duration are bounded.

Geo-located DNS resolution — resolve hostnames from specific countries to see how CDNs, geo-blocking, and DNS-based routing differ by region.

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.

Per-agent budget enforcement — track an agent's cumulative spend against a cap and block overspend. Part of x402 Agentic, the payment-trust suite for AI agents on Base USDC.

Fetch any public URL and return a clean, readable markdown or JSON extract for AI agents. Pass the target as ?url=<encoded>. Ideal when you need to read webpages, docs, or articles without a browser. Blocks script/style tags, normalizes links and images, strips HTML.

Agent income rebuild: every payment into an agent wallet in one asset (an ERC-20, or native ETH including escrow withdrawals) between two blocks, with the draft Agent Income Statements exclusions (zero, mints, self, optional owner top-ups), payers that are contracts flagged, and an optional claim= compared as matched or mismatched. Ethereum, Base and Robinhood Chain. Independent, by Blockpin; not

Analyze a Base Mainnet token contract: block-pinned owner(), ERC-1967 proxy slots, ERC-20 metadata, code hash, best-effort source match and prior-snapshot comparison when available. Free POST /v1/prepare returns report_id; paid GET /v1/report reads it for 0.01 USDC via x402. Not a security audit.

Real-time crypto sentiment for a ticker symbol (e.g. BTC, ETH, SOL) from 9 crypto news RSS outlets (CoinDesk, Cointelegraph, Decrypt, Bitcoin Magazine, The Block, CryptoSlate, NewsBTC, CryptoPotato, The Defiant) and the Fear & Greed Index. Headlines from the last 72h, weighted toward the newest. Returns a bullish/bearish/neutral label (or 'insufficient recent news'), score, sample size and the top

Options flow intelligence — unusual activity put/call ratios large block trades

Sends a real request to any URL you provide, attaches an Origin header, and reads back all six standard cross-origin permission headers the server returns. Tells you whether cross-origin requests are enabled at all, whether your specific origin is permitted, and shows every permission value exactly as the server sent it. Useful for finding why a browser is blocking a request, confirming a new depl

Multi-chain EVM gas price oracle for AI agents — 17 chains (Ethereum, Base, Arbitrum, Optimism, Polygon, BNB, Avalanche…). One x402 call returns slow/standard/fast EIP-1559 tiers as DROP-IN maxFeePerGas + maxPriorityFeePerGas in wei (plug straight into a viem/ethers tx, no conversion, exact even on sub-gwei L2s), plus base fee, head block, and fullness, from a live eth_feeHistory call. Pass ?chain

Overwing guardrail: check text before you send, post, or act on it. Content moderation, PII detection, confidential leak detection, toxicity, self-harm and severity in ~150 ms. Returns a verdict plus one recommended_action (block / redact / review / allow) with calibrated confidence. Pass context (recipient, channel, owns_contact_info) with the outbound-message set. $0.002 USDC, no account.

Use before paying a supplier invoice to check that the supplier is who it claims to be. Reconciles the claimed legal name, company registration number and VAT number against the Irish Companies Registration Office (IE) and the EU VIES VAT service, and returns an advisory RELEASE, REVIEW, BLOCK or INSUFFICIENT_EVIDENCE decision with per-check results and reason codes. Advisory only: it never execut

Parser-blocking script budget repair plan fetches current public evidence from the supplied target and evaluates the documented criterion. It returns the observation, threshold, verdict, exact evidence source, limitations and a mode-specific action. The check is passive: no login attempt, payload injection, exploit, purchase, form submission or load test is performed.
