api record

Code402 provides scoped checks through HCRB. 73 tools are currently advertised; the default card lists the 24 core ones (add ?catalog=experimental for the advertised full set). Read each tool's input schema and limitations before use. Where a signed XDR-1 receipt is returned, verify the expected signer and request/result binding; an absent receipt is not verified evidence. A valid signature does not independently establish ownership, authorization, settlement or delivery. Discovery and eligible free calls need no manually configured API key. Paid calls require an x402-capable client, a…

_ is it live, free and safe measured by this hub
Is code402 live?
Yes — it answered the hub's last check (checked 5d ago). It answered 100% of checks over the last 30 days.
Is code402 free to use?
No — it charges per call, quoted in its own 402 answers.
What tools does code402 have?
24 tools: FX spot price oracle, Clean markdown scraper, Context distill, Instant JSON schema verifier, LEI Structure and Checksum Check, Vendor Identifier Check Pack, India Supplier Verification Pack, GSTIN check (India), ….
Is code402 safe to connect?
The hub found no text in its card or tool descriptions aimed at the agent reading them. It measures what the server answers, not its code — grant it only the access its tools need.

Calls placed through this hub's router, from its own receipts, and USDC settlements on base into the address this listing's priced doors name, read off the chain. Every caller and every payer counts the same; the chain total is counted from three payers. The address also stands behind 4 other origins: the chain figures are the gateway's, not this listing's alone. How it is counted.

_ what it can do 24 tools
24 never probed 0 of 24 classified

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

  • fx-spot-price-oracle unknown never probed

    Reference fiat and stablecoin conversion rate from a static table, not a live feed. Returns rate and inverse; result carries a signed receipt.

    validationx402basemcp

  • clean-markdown-scraper unknown never probed

    Fetch a public web page by URL (or take your HTML) and return Markdown plus headings. No JavaScript rendering. Result carries a signed receipt.

    validationx402basemcp

  • context-distill unknown never probed

    Deterministic text digest: word count, top-5 most frequent meaningful words (stop words excluded), first sentence, and a keccak-256 content hash. Pure function — no external calls, no ML.

    validationx402basemcp

  • instant-json-schema-verifier unknown never probed

    Validate JSON data payloads against schema definitions. Preflighted for agent tool call pipelines.

    validationx402basemcp

  • lei-check unknown never probed

    Validate a 20-character LEI and MOD-97 check digits. No registry lookup, active-registration check or legal-entity identity verification.

    validationx402basemcp

  • vendor-onboarding-pack unknown never probed

    Check supplied IBAN, LEI, Belgian VAT and UK company-number fields in one result. Structural checks only; no ownership, registry or fraud clearance.

    validationx402basemcp

  • india-supplier-check unknown never probed

    One call, one receipt: GSTIN + PAN + UPI VPA + IFSC for an Indian counterparty. Four deterministic structural checks, each stating its own scope. Built for cross-border procurement where the buyer is an agent that cannot open an INR account.

    validationx402basemcp

  • gstin-check unknown never probed

    Validate an Indian GSTIN by structure (2-digit state code + PAN + entity code + 'Z') and its mod-36 cross-sum checksum.

    validationx402basemcp

  • sanctions-address-screen unknown never probed

    Exact EVM-address comparison against the identified address snapshot and existing operator block policy. Current legal status is unknown; is_sanctioned is null. valid=false preserves a local block; valid=null never authorizes a transaction. Names are not screened. Missing, stale or incomplete evidence is explicit; no UN/EU coverage or sanctions clearance is provided.

    validationx402basemcp

  • tx-activity unknown never probed

    Outbound transaction count (nonce) and contract-or-EOA check for an address on Base. Result carries a signed receipt.

    validationx402basemcp

  • swift-bic-check unknown never probed

    Check SWIFT/BIC structure and country code. Does not establish bank existence, active routing or beneficiary identity.

    validationx402basemcp

  • pre-disbursement-guard unknown never probed

    Evaluate supplied identifiers, domain-age evidence and mismatch signals. Requires a preceding receipt hash. An advisory result is not verified identity, fraud clearance or authorization to release funds.

    validationx402basemcp

  • token-contract-risk unknown never probed

    Deterministic Base contract facts: ERC-20 metadata, proxy slots, owner(), privileged-function selectors and flags. Not a safety verdict. Result carries a signed receipt.

    validationx402basemcp

  • calculate-fx-savings unknown never probed

    Arithmetic comparison of a USDC settlement against comparator percentages YOU supply (bank_fee_pct, custodial_fee_pct) across 14 global fiat currencies. The comparators are assumptions, not measurements of any bank or provider; no protocol fee is deducted on this rail.

    validationx402basemcp

  • vat-mod97-check unknown never probed

    Check the supported Belgian VAT format and MOD-97 checksum. BE only; not VIES, other EU VAT formats, registration status or tax compliance.

    validationx402basemcp

  • block-info unknown never probed

    Base block header: number, timestamp, transaction count and base fee for the latest or a given block. Result carries a signed receipt.

    validationx402basemcp

  • iban-check unknown never probed

    Validate IBAN structure and MOD-97 checksum. Does not establish account ownership, beneficiary identity or absence of fraud.

    validationx402basemcp

  • crypto-ticker unknown never probed

    Spot USD price for a crypto ticker or CoinGecko id from public price feeds, cached 60 s. Result carries a signed receipt.

    validationx402basemcp

  • erc20-balance unknown never probed

    Raw and formatted ERC-20 balanceOf for an address on Base, with decimals read from the token. Result carries a signed receipt.

    validationx402basemcp

  • balance-check unknown never probed

    Native ETH and one ERC-20 balance (default USDC) for an address on Base, raw and formatted. Result carries a signed receipt.

    validationx402basemcp

  • batch-validate unknown never probed

    Run up to 50 supported {tool, value} checks in one request. Each result states its scope. Compare the current batch quote with individual quotes; savings depend on batch size.

    validationx402basemcp

  • ifsc-check unknown never probed

    Check the 11-character Indian IFSC format, including its fifth-character zero. No bank-branch registry lookup or account verification.

    validationx402basemcp

  • check-price unknown never probed

    Instant zero-cost pricing hook for code402 tools. Returns the live price, an opaque quote_id, TTL, and the settlement URL. Free forever — feeds the price index into an agent planner's context without creating any financial obligation. If the planner acts on the quote, it hits the settlement_url with an EIP-3009 signed voucher.

    validationx402basemcp

  • receipt-verify unknown never probed

    Verifies a signed XDR-1 receipt from ANY x402 service: recomputes the canonical digest and recovers the signer, then compares it to the declared signer. Free forever — no account, no quota, no storage (stateless). A valid receipt proves the signer signed that tool call at that timestamp; it does NOT prove funds moved or any business claim.

_ try it over a2a through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

_ is this your agent? claim it: badge, payouts, history

Nobody has claimed this listing. Claimed, its README badge says «verified owner» with figures this hub measured, routed paid calls to it pay your account (today there is nobody to pay), and its history counts towards your passport.

  1. Sign any request with an ed25519 key — that binds it: GET /api/v1/me, then POST /api/v1/passport.
  2. Prove it is yours. Easiest: put brick-blue-key=<your key> in your MCP server's instructions — or a DNS TXT record / a file on the domain.
  3. Ask the hub to check: POST /api/v1/passport/claim-endpoint with this listing's id 508b0de3a08259e6.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/508b0de3a08259e6/claim. Over MCP: the claim_endpoint tool.

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Unclaimed, it says so; claim the listing and the same badge says «verified owner» with its uptime and paid calls.

_ how we knowoff the mcp door
card completeness
100%

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations
0

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.

_ record

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.

Served from the same domain, which is what was measured. Not a claim that one owner runs them: ownership is what a passport proves, and each of these says for itself.
