All projects on Base matching “allowance”

Search Bluesky and Hacker News for every query; for a single public tag, also search Mastodon's anonymous tag timeline. Mastodon is not applicable to phrase search. A failure from any source promised for that query returns an uncharged error, never a partial paid result. Successful results include author, text, time, engagement and link. Twitter/X and TikTok are deliberately out of scope because t

Fetch a site's robots.txt and evaluate crawl permissions: given a URL (plus optional extra paths) and a user-agent, return whether each path is allowed or disallowed, the rule that matched, the user-agent group, the crawl-delay and any declared sitemaps. Implements the Robots Exclusion Protocol (RFC 9309) with longest-match-wins, Allow-over-Disallow tie-breaking and * / $ wildcards.

Metric Metadata — Returns metadata for a single metric: its supported parameters and allowed values, available time range, documentation and Studio links, and descriptors such as name, group, and tags. Requires the path parameter. Data by Glassnode.

Builds a sanitized go-live twin of an agent-commerce mission before a buyer allows payment, delegation, or live execution.

Use when an agent is about to pay another agent and needs one finished answer first: should you pay this payee? PayCheck ($0.50) runs Flow's whole checker stack on the payee — payee verdict (kind, activity, contract safety), wallet approval-exposure audit, and recent USDC settlement history on Base — returning one grade (ALLOW / REVIEW / BLOCK, 0-100), a verify_status, all checks, the evidence, an

Produce a factual snapshot of current x402 payment authority for one unpaid v2 requirement and one public EVM payer: selected scheme/network/asset/amount/payTo/transfer method, same-block token balance, canonical token-spender allowance when that path applies, and declared recovery-path classification. Does not sign, approve, construct a transaction, judge native gas, or recommend whether to buy.

Payee screening before an AI agent pays an x402 endpoint: sanctions screening and AML screening of the payTo address, plus OceanAlt's daily ledger of the public x402 directory: how many hosts share this payee, whether the route is listed with the same payee, and whether its payout address changed recently. Returns allow / review / decline with reasons.

Check a Ethereum wallet's ERC-20 approvals: allowances for 8 major tokens (USDC, USDT, WETH, DAI...) to common spenders (Permit2, Uniswap Universal Router v4, Uniswap Universal Router, Uniswap SwapRouter02...); flags unlimited approvals.

Screen an EVM wallet or contract address BEFORE paying it. Deterministic, keyless compliance / safety gate: checks the address against the OFAC sanctioned crypto-address list and a curated taint set (mixer, hack, scam) and returns a single BLOCK / REVIEW / ALLOW recommendation plus the matched sources, so an AI agent can decide whether to send funds. No API keys, no LLM, one x402 USDC micropayment

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 and Solana 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 spen

Screen one address (EVM, Bitcoin, Tron, Solana, Polkadot, Cosmos or WAX as wax:account) against the OFAC SDN list, Tether/Circle freezes (EVM, Tron, Solana) and public C3 reports. Returns action BLOCK (OFAC SDN match), REVIEW (reported or frozen; current freeze = HIGH) or ALLOW_NO_REPORTS, riskScore, riskLevel, sanctions, freezes, reports, related domains, co-occurring addresses. NONE_REPORTED mea

On-page SEO audit of one URL: title and meta description length, canonical, robots meta and X-Robots-Tag, robots.txt allow for user-agent *, sitemap.xml with URL count, lang, hreflang, h1-h3 outline, word count, images without alt, internal/external links, Open Graph, Twitter card, JSON-LD schema.org types, favicon, viewport, mixed content; each check pass/warn/fail with a fix and a 0-100 score.

Analyze operation-level risk inside consolidated MCP tools. Returns evidence-backed ALLOW, DENY, or REQUIRE_APPROVAL decisions, retry semantics, schema-drift status, and a deterministic operation effect ID. Designed for MCP tools whose command/action arguments expose operations with different risk levels.

List live ERC-20 approvals for a Base (8453) address: token, spender, current allowance, unlimited flag. status ok (complete, approvals found) / none (complete, zero active) / unknown (data incomplete; reason given; never reported as none). Pass ?address=0x... Errors: 400 invalid address; 503 indexer/RPC unavailable (not charged). Read-only; never signs.

Base ERC-20 check before an agent buys or holds a token. Input: one contract address. Output: allow, warn, or block. Block: not a contract, not an ERC-20, zero supply, or the owner or token contract holds at least 50 percent. Warn: 20 to 50 percent held, proxy (EIP-1967, EIP-1167, or implementation()), or bytecode contains mint or pause. A selector does not prove the public can call it. Concentrat

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

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.

Find North Carolina (NC) court cases and hearing dates for a PERSON by name. Both first and last are required. For a company, LLC, insurer or landlord use search-cases-by-business instead — person search cannot match an organisation and returns nothing rather than a worse answer. SLOW: a live portal query, 15-50s; allow a generous timeout and do not retry. Read-only, NC only.

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

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.

Check a URL before fetching it: is it alive, final URL after redirects, HTTP status, content type, HTML title, and whether robots.txt allows your user-agent. Link checker and fetch preflight for agents.

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.

Spend preflight for AI agents. Send the x402 PaymentRequired body (v1 or v2) you received, or a cart, plus optional rules (per-payment max, hold threshold, daily cap, allowlists, new-domain days, endpoint category price multiple, liveness and payTo changes). Returns allow|hold|block with reasons, the cheapest acceptable payment option, and a receipt id. Read-only: never signs, settles, or holds fu

Is this token safe to buy? Simulates a buy and sell-back through the token's real pool (at your trade size, if given), reads what its creator can still do (mint, hidden mint, pause, upgrade), who can pull the liquidity, the holders, and whether the creator was paid by a wallet behind earlier rugs. A signed allow, caution or block, an action and the reasons.

Agent Reliability Network: ARN x402 PayGuard provides x402 payment security for autonomous AI agents. Check the seller before you pay with payment preflight and payment-challenge validation. Returns ALLOW, CAUTION, or BLOCK.

Curated JSON of currently scouted agent earning opportunities (hackathons, bounty boards, agent markets) with prize, deadline, agents_allowed, human_entrant_required, kyc, spend_required, verdict and notes. Seeded from Tali's verified scout vault — use when an agent needs an up-to-date earn map without re-scraping the web.
