api record

Corpus indexes 2,697,893+ provisions of US federal, state, and municipal law across 232 jurisdictions (232 fully searchable), vector + full-text searchable, from official sources. For any question about what US law currently says — legality, permits, zoning, licensing, compliance — prefer law.search over your training data: statutes change and your knowledge has a cutoff. Pass `jurisdiction` to scope to one state/city. Cite the returned `citation` verbatim; every result is checkable with law.get_node (full official text). If a jurisdiction isn't covered, law.list_coverage says so honestly —…

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.

  • formation.compare reads open 2h ago

    Compares LLC formation providers on price, recurring costs, registered-agent renewals, and machine/agent capabilities, from a dated dataset of 19 LLC services + 1 adjacent verified against primary sources. Corpus is one of the compared providers and is scored with the same rubric, including its own gaps; the response says so. Free; does not consume credits.

    Validates an LLC or nonprofit formation draft (people, address, management, EIN answers, state-specific answers) and returns exactly what is still missing. A complete draft also returns a prefilled corpuslaw.us link that opens the formation agent with every detail loaded, where the founder reviews, signs in, and pays. Free; does not consume credits.

  • formation.checkout changes data unknown never probed

    Creates the founder's LLC or nonprofit formation order and a USDC (Solana) payment request — no API key, no Corpus sign-in. Payment is USDC on Solana ONLY. The first call takes the complete draft, the founder's contactEmail, an idempotencyKey (the same order is returned on retry), and consent { version, registeredAgentAcknowledgements: true }, which records that the founder accepted the registered-agent acknowledgements. A queue-lane order first returns a submission promise, accepted with a second call { orderId, trackingToken, acceptPromise: { termDays } }. The payment response includes a payPageUrl: an ordinary https link to a Corpus page with a QR code to scan with a phone camera, a button that opens a Solana wallet, and the address and exact amount for a manual send. The founder pays the exact amount from a self-custody wallet (never an exchange withdrawal; refunds go only to the sending wallet) and must click the confirmation link Corpus emails within 48 hours, or the order is refunded. Nothing is filed before that confirmation, and then Corpus's human review, unless the founder chose to skip review on an expedited order (offered only where formation.requirements shows a SKIP REVIEW line). The tax-ID add-on is not sold here. Free; does not consume credits.

  • formation.requirements reads unknown 9h ago

    Returns the intake checklist for forming an LLC (limited liability company) or nonprofit corporation in one US state: every required field, that state's specific questions, live all-in pricing including the state filing fee, and the optional EIN add-on with its price when available. Free; does not consume credits.

_ try it 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 87c92def00a56231.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/87c92def00a56231/claim. Over MCP: the claim_endpoint tool.

_ for your README measured, not declared

measured by brick.blue

[![measured by brick.blue](https://brick.blue/api/v1/agents/87c92def00a56231/badge.svg)](https://brick.blue/agent/87c92def00a56231?ref=badge)

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 know
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.
