Every agent-payable API.

Fresh EU public procurement notices from TED (Tenders Electronic Daily, official Publications Office API, new notices daily). Query: ?cpv=48000000&country=FRA&days_back=7&limit=10 (cpv = 8-digit CPV code, country = 3-letter buyer country, all optional). Each notice: publication_number, publication_date, title, buyer_name, tender deadline, notice URL. 1h cache.

One-call verification of a European company: official registry existence and status, insolvency signals, VAT (VIES), LEI (GLEIF), sanctions screening (EU/OFAC/UN/UK/FR), EORI and domain age, condensed into a pass/review/fail verdict with per-check source, timestamp and an explicit coverage map. Query: country=FR (FR, UK, IE, NO, FI, SK, PL, CZ, CH) and id=552032534 (national registry number). Factual verification, not a credit score. Buyers are never charged on failure.

Reputation of a public IP address for anti-abuse and KYC. Returns ASN, AS-org, country, datacenter/hosting classification, Tor-exit and Spamhaus DROP flags, plus a deterministic risk score with reasons.

Fit-to-haul verdict for a US motor carrier from FMCSA registration data. Give one of dot, mc or name and get a verdict (fit, caution, unfit or not_found), a 0-100 fit score, per-dimension flags, reasons and weighted signals across authority status, operation, hazmat, safety rating, history, registration freshness, address and fleet. Deterministic, no LLM. Carrier vetting indicators, not legal or compliance advice.

Native-coin balance + ERC-20 token balances (raw + human) for any address on Base, Ethereum, Arbitrum, Optimism, Polygon or BNB (default Base). On Base pass token symbols or 0x addresses (or a default common set); on other networks pass explicit 0x token addresses.

One-call pre-transaction guard for agents: bundle the transaction you're about to sign/send and get every applicable safety check in a single payment — signature-intent decode, live threat-DB + address-poisoning look-alike on the recipient, and a drainer audit of standing approvals. By design no combined safe/danger verdict is emitted; each sub-check's flags & evidence come back verbatim so your agent decides. Replaces 4 separate 402 round-trips with 1. Deterministic, no LLM.

A composite US real-estate market profile for one geography. Fuses the FHFA House Price Index momentum, Census ACS demographics, housing, income, tenure and vacancy, national housing context, and Fair Market Rents into one cited JSON with computed derivatives such as gross rental yield and affordability. Aggregate market tier, not a per address valuation.

The FHFA House Price Index for a geography: the current index level plus year over year, quarter over quarter and five year growth, with momentum flags and a short history. State and metro CBSA levels are covered directly; county and ZIP resolve to the state level index. Public domain, US only.

What changed in the x402 Bazaar catalog since yesterday: price changes and payTo changes (the address you'd pay moved — a pre-payment guard). ?type=price,payto to filter. Objective a->b diff, no labels — only a holder of past daily snapshots can compute it. For registries/agents that must not route on stale data.

Machine-readable map of the x402 service ecosystem on Base: price range, category, endpoint count, live health & latency per service — built from our continuous catalog+reliability scan. ?since=<unix> for newly-launched services; ?category=/?health=/?sort= to filter & rank. Skip scanning the whole Bazaar yourself. Objective facts, machine-readable.

Census of the x402 ecosystem from our daily Bazaar snapshots: which domains launched or disappeared since yesterday, price-median drift, and network mix. ?kind=new|gone for the machine-actionable churn roster, or full pulse with aggregate + timeline.
