x402-preflight: confirm your wallet can transact, and see your balance, in one certified call. Pay $0.01 USDC on Base, get a signed on-chain-anchored receipt. The safe first transaction before you ship real volume.

🆕 Since Pectra an EOA can carry EIP-7702 delegated code (the 0xef0100 designator): every call to the wallet executes the DELEGATE's contract with the wallet's funds — a malicious delegate is total takeover, invisible to approval tools. Reads the designator, resolves the delegate and verdicts it: not_delegated / delegated_known (Coinbase's EOA→SmartWallet path) / delegated_unknown (🚨) / smart_contract. The drain surface no other Base tool checks.

Turn ANY text into clean, schema-enforced JSON: pass text= plus the fields you want (fields=name,email,price,date — up to 10) and get exactly those keys back, guaranteed-valid JSON via Claude structured outputs. Add list=true to extract EVERY repeated record (invoice lines, listings, table rows) as an array. Up to 16K chars per call. Not crypto-specific — the universal parse step for agent pipelines: pages, emails, receipts, logs.

The zoom-out flagship: aggregates trending and newly-listed Base tokens, then Claude writes a concise market brief — mood, highlights, new & notable launches, and cautions (fresh/unknown tokens flagged for rug risk). One call gives a trading agent market context instead of dozens of lookups.

POST /api/scan — agent-readiness scan for a domain (~$0.01 USDC per call)

Compress up to 16K characters of anything — articles, transcripts, email threads, reports — into 3-5 precise bullet points, one micro-payment per call. No API key, no subscription, no prompt engineering: send text=, get bullets back as clean JSON. The digest step for agent pipelines that read more than they can carry in context.

Claude-quality translation as a pay-per-call primitive: send text= (up to 6K characters) and to= any language, get only the translation back — no notes, no wrapper prose, safe to pipe straight into the next step. One USDC micro-payment per call, no API key or subscription. Built for agents localizing content, parsing foreign-language sources, or serving multilingual users.

AI Web Extractor — turn ANY url into clean, LLM-ready markdown. POST {url}; get the main content as markdown (boilerplate/nav/ads stripped) with title, description, and links. The scrape / read / url-to-markdown primitive for RAG and research agents. Fast, cheap, x402-native.

AI-powered web search via Tavily

Deterministic package existence for PyPI and npm, built from real published artifacts (never LLM guesses). Negative answers and typosquat-adjacency flags carry signed proof. $0.002 USDC per check.

Full signature for a symbol in a PyPI or npm package at an exact version: structured params, docstring, deprecation flag with since-version, extracted from the real artifact with signed proof. $0.01 USDC per lookup.

Deterministic symbol existence for PyPI and npm packages: functions, classes, methods, constants with signatures and deprecation flags, extracted from real artifacts. Negative answers include closest matches and signed proof. $0.005 USDC per check.

ATMS x402 challenge — crawler / probe endpoint (always 402, no side effects)

Active-pump detector: is the asset currently pumping, and for how long vs the historical average pump length? Use to judge whether a move is fresh or exhausted before joining it.

Ada Usd — an agent-callable ada usd service, payable over x402 (USDC on Base). Provided via Apify. Priced around 0.01 USD per call.

🆕 The 'who am I dealing with?' check for agents. Reads Coinbase's ONCHAIN verification (an EAS attestation by verifications.coinbase.eth) — meaning the address is tied to a KYC'd Coinbase account, the strongest sybil-resistance signal on Base — plus the address's Basename. Returns a verified/named/anonymous verdict + trust score. Pair with sign-guard/spend-audit for a full pre-transaction gate. Identity is a signal, not proof of honesty.

Full machine-readable list of crypto addresses under Japan MOF asset-freeze sanctions (外為法), with designated-entity context (name, notice date, UN ref). Source: Ministry of Finance Japan official CSV, updated daily, attributed per 公共データ利用規約. Factual data; not legal advice.

Aegis curated briefing — AI-scored content feed with V/C/L metrics

Look up an ERC-8004 AI agent identity on Base mainnet. Returns name, description, services, x402 support, and owner.

AI agent action safety: one-cent deterministic preflight for every consequential agent command. Returns risk, matched rule ids, and an exact machine-readable escalation call: full DestructGuard evidence for medium risk or the complete Action Safety workflow for high and critical risk.

Agent guardrail decision engine. Call once before every agent action; returns a single decision — proceed, slow down (with a reason and wait time), or stop — based on cost budget, chain depth, step cap and retry budget, and request volume pressure. Policy thresholds are configured separately via /policy; this endpoint only reports the decision for a single action.

Agent profile lookup. Returns trust score, component breakdown, feedback counts, and metadata for any ERC-8004 agent.

Static pre-install analysis of a skill/tool — VERIFIED/FAILED + violations (per call)

Agent-SOFR — decentralized USD short-rate benchmark for AI agents. Weighted-median of 7 sources + variance + regime premiums. BNS-calibrated 6-mode classifier on 444k ETH/USDC 5-min bars (λ=1.097 closed-form). Open + IPFS-pinned methodology: agent-sofr-v1.

Cross-chain ERC-8004 trust score for one (chain, agent) pair — signed JSON with transparent component breakdown (value_avg / client_breadth / volume / recency), per-chain context, and methodology link. USDC pay-per-call on Base mainnet.

Audits a website for AI agent and AI crawler readiness from artefacts the caller supplies: robots.txt, HTML, response headers, llms.txt, sitemap lastmod values, /.well-known paths. Names the crawler policy per bot (GPTBot, ClaudeBot, PerplexityBot, CCBot, Google-Extended, Amazonbot, Applebot, Bytespider) and reports what it could not measure instead of guessing. Makes no outbound request.

Current weather conditions for any location on Earth: temperature, feels-like, humidity, wind speed/direction/gusts, precipitation, cloud cover, pressure, and human-readable condition. Open-Meteo, no key, global. ?lat=48.86&lon=2.35.

Compress a string with Brotli (RFC 7932) and return it as base64. Brotli typically beats gzip by 15-25% on text - useful when bytes matter (e.g. cramming context into an LLM prompt, fitting under a transport cap). Slower than gzip; pick gzip if sp...
