Company due-diligence dossier - MAX (exhaustive)

The exhaustive due-diligence tier: more filings, a full year of Form 4 insider activity, wider web research (up to 8 angles), the widest source set, and a ~2,800-word cited dossier with a full source table. Send POST /v1/dossier/max with the required field ticker and pay $1.10 per call over x402 with USDC on an EVM chain. It returns a JSON object with dossier, company, ticker, sources, tables and 1 more.

For a decision that warrants real diligence. USDC or card (Stripe). Not cached.

  -H "Content-Type: application/json" \

From an MCP client

catalog.call {
  "slug": "dossier-max",
  "params": {
    "ticker": "AAPL",
    "focus": [
      "debt",
      "litigation"
    ]
  }
}

The hosted connector at https://agent402.tools/mcp needs a payment for dossier-max; the stdio package pays it from a wallet or from AGENT402_CREDITS_KEY. Local install: npx -y agent402-mcp.

Errors and behavior

• ticker is required. An input the tool rejects returns an HTTP 4xx whose body carries error, tool, expected, required and example, so the caller can correct it.
• A paid call that ends in any status of 400 or above is not charged over x402, MPP or a prepaid credits key: settlement is cancelled when the tool fails.
• Wallet-only: this tool runs a model, so it has no proof-of-work tier. A prepaid card-credits key (Authorization: Bearer a402_...) also pays it.
• Model-backed: the answer is generated by a model, so the same input can produce different wording.
• Long-running: payment settles after the work finishes, so only EVM exact payments are offered.
• A GET or HEAD to /v1/dossier/max returns the same 402 quote, so the price can be read without a body.
• An Idempotency-Key header makes a retried paid call replay the first 200 instead of charging again (an answer larger than 1 MB and a streamed response are not replayed).

Paid call (JavaScript agent)

import { wrapFetchWithPayment } from "@x402/fetch";
import { x402Client } from "@x402/core/client";
import { registerExactEvmScheme } from "@x402/evm/exact/client";
import { privateKeyToAccount } from "viem/accounts";

const client = new x402Client();
client.setSpendControls?.(false); // keep your own spending ceiling in code
registerExactEvmScheme(client, { signer: privateKeyToAccount(KEY) });
const payFetch = wrapFetchWithPayment(fetch, client);

const res = await payFetch("https://agent402.tools/v1/dossier/max", {
  method: "POST",
  headers: { "Content-Type": "application/json" },
  body: JSON.stringify({
    "ticker": "AAPL",
    "focus": [
      "debt",
      "litigation"
    ]
  }),
});
