api.eucompliance.tools x402 offerings

Pre-flight check before a swap or transfer: ERC-20 allowance, balance, decimals and symbol in one call, read live from the chain at the latest block. Pass an amount and get a straight would_succeed verdict with the blocking reason and the action needed. Base, Ethereum, Arbitrum, Optimism, Polygon. A missing approval burns the gas of a failed transaction - this call costs a fraction of that.

What happened to my transaction? Status, block, gas used, fee paid - and if it failed, the revert reason in plain text, recovered by replaying the call against its block. The receipt alone does not carry that reason.

Agent Transaction Guard: should an autonomous agent proceed, review or block this transaction? Five read-only on-chain core checks before gas is spent: native balance and gas price, transaction-specific gas estimate, full simulation with decoded revert reason, pending nonce gap and recipient bytecode/type. Supplying token, amount and an optional spender adds an ERC-20 balance and allowance check. Returns a stable machine-readable decision, evidence, unknowns, limitations and safe next actions. Missing evidence is REVIEW, never a false approval. Read-only; no transaction is broadcast and there are no follow-up charges. Wallet sanctions screening is outside this contract because official name lists cannot clear or identify a blockchain address.

Complete Base-USDC outflow evidence for an AI agent: reads every outgoing transfer, converts it to EUR using a dated ECB reference rate, groups by recipient and returns all rows as JSON or CSV with signed evidence. Transfers remain unclassified until linked to supplier identity, invoice and supply type; no VAT treatment is guessed.

Computed crypto-market indicators, not a data relay. We buy raw upstream x402 feeds and compute a disclosed, reproducible market-regime score (0-100). market_brief adds free context: BTC/ETH exchange-median spot, perp funding and our archived 7-day score trend. Every paid response includes a stable repeat URL and freshness-based not-before timestamp for autonomous scheduling. Products: market_brief, yield, gas. (Soft commodities: separate feed at /x402/commodities.)

AI Act Article 50 disclosure - the privacy-first GET path: pass only the SHA-256 of your AI output (content_sha256), never the text itself. Get back the signed provenance record, the human-readable disclosure in DE and EN, and the obligations that apply to the deployer. Your content never leaves your system. Use POST with 'content' if you want us to hash it for you.

E-invoice validator for EN 16931, XRechnung, ZUGFeRD, Factur-X and Peppol BIS: upload the XML or a ZUGFeRD PDF and the COMPLETE official EN 16931 Schematron rule set is applied (CEN validation artefa…

JSON-RPC for five chains through one endpoint, no account and no API key: Base, Ethereum, Arbitrum, Optimism, Polygon. Two things a bare node does not give you. Failover: several public nodes per cha…

Web content extraction for agents at the lowest price in this catalog tier: pass a URL, get the readable content as clean markdown or plain text - title, author, date, main text, tables, links. Direct fetch, no third-party search index resold. 3 MB / 20 s caps, internal addresses refused. Fixed $0.003 per fetch, signed receipt included.

EU VAT decision engine for invoicing and e-invoicing: determines place of supply, reverse charge, intra-Community supply, export or domestic VAT, returns the rate and the EN 16931 / UNCL5305 VAT category code (BT-151) plus exemption reason code (BT-121) and ready-to-use invoice wording (EN/DE) with the legal article reference. For XRechnung, ZUGFeRD, Peppol BIS and OSS workflows.

Counterparty due diligence in one call: validates the EU VAT ID against the live VIES register, screens the company or person against the official EU consolidated sanctions list, checks the IBAN, and returns a traffic-light verdict (clear / review / blocked) with reasons and a recommendation. Built for onboarding a new supplier, customer or payee automatically. Every finding cites its official source and data date. Clear results include safe VAT/e-invoice next actions; review or blocked results stop the automatic workflow. Recheck timing prevents unnecessary repeat purchases.

LLM completion per call, no account and no API key: POST a prompt (or a messages array) and get the model answer as JSON. Hard caps disclosed in every response (6,000 UTF-8 bytes in, 750 tokens out on this tier). Fixed price per call, signed receipt included so the answer stays auditable. Larger tier at /x402/chat-plus.

LLM completion per call on a stronger model, no account needed: POST a prompt or messages array, get the answer as JSON. 6,000 UTF-8 bytes in, 1,200 tokens out, fixed price per call, hard caps disclosed in every response, signed receipt included. Smaller and cheaper tier at /x402/chat.

Crypto spot price that attempts three independent public exchange tickers (Binance, Coinbase, Kraken) and takes the median of the live replies. Every delivered quote, the spread and the timestamp are disclosed. Refuses to answer from fewer than two live sources. Query: symbol (BTC, ETH, SOL, ...). $0.001 per call, signed receipt included.

Company register lookup from the official national registers: France (Annuaire des Entreprises), Norway (Brønnøysund), Czechia (ARES), Finland (PRH), Slovakia (RPO), Poland (KRS). Name, registration number, status, legal form, address and registration date, normalised. Search by name or registration number.

Historical time series that no upstream provider sells. They sell the current value; we archive every value we buy, so the series over days and weeks becomes ours alone - it cannot be copied because a competitor lacks the past. Products: gas (Base gas price, Gwei), yield, commodities, market_brief. The scoring rule and point count are disclosed in every response. At least two usable points must remain after raw or daily resolution; an empty, one-point or incompletely readable archive returns an uncharged error and is never sold as a time series.

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 their terms forbid scraping. Query: q, limit. $0.002 per successful call, signed receipt included.

Per-coin positioning brief: at-least-two-exchange spot median (attempting Binance/Coinbase/Kraken), Hyperliquid funding, open interest, premium and volume. The disclosed 0-100 crowded-long/short score uses funding and premium; the 6-hourly archive trend is separate context and may still be filling. One call per coin. Signed, verifiable receipt included.

Perpetual futures market data from the Hyperliquid public API: mark and oracle price, hourly and annualised funding rate, open interest, 24h volume and max leverage per market, sorted by volume. Query: coin (optional, e.g. BTC) or top=N. Source and timestamp in every answer, 10 s cache. $0.005 per call, signed receipt included.

Sanctions screening (AML/KYC) against three official lists in one call: EU (Commission FSF), UN Security Council and UK (HM Treasury OFSI) - 12,000+ entities, 50,000+ name variants, re-indexed daily, fuzzy matching. Each hit states its list, programme, reference and the list date. The signed response includes a versioned compliance workflow, an exact counterparty follow-up URL when safe, and a daily recheck-not-before time. Optional lists=eu,un,uk.

Soft-commodity indicator with a disclosed weather-only stress score from Brazilian growing-belt rainfall and dry days. A paid result also includes at least one usable Ivory Coast cocoa-or-coffee farmgate-price observation from a distinct source as context; availability of both is not guaranteed.
