Answer-engine brief

Canonical answer for DealAnalyzer

Pricing
Direct answer
DealAnalyzer is a deterministic x402 API for AI agents. Full deal underwriting — DCF, returns, sensitivity & waterfall in one call.
When to use
Use it when an agent needs a repeatable computed result with evidence instead of asking an LLM to improvise a number or risk decision.
Inputs
dcf, returns, waterfall, sensitivity
Outputs
service, requestId, valuation, returns, sensitivity
Pricing
$0.25 per call, paid over x402 in USDC on Base. No API key is required.

What it does

Premium deal underwriting in one deterministic call: a DCF valuation (enterprise value, equity value, implied share price; Gordon-growth or exit-multiple terminal), equity returns (IRR/XIRR, NPV, MOIC, payback), a discount-rate × terminal-assumption sensitivity grid, and the LP/GP distribution waterfall on the proceeds. Pure math from caller-provided inputs — no market-data feed, no fabrication — with evidence-backed findings on every section and a signed response receipt.

  • DCF valuation: enterprise value, equity, share price
  • IRR/XIRR, NPV, MOIC + a sensitivity grid
  • LP/GP waterfall on the DCF proceeds

Top-level request fields. Nested shapes are shown in the example above and the OpenAPI spec.

FieldTypeRequiredDescription
dcfobjectYesRequired. DCF valuation inputs.
returnsobject—Optional. Equity cash-flow stream for IRR/XIRR, NPV, MOIC, payback.

How to call it over x402

  1. 1. Send the request. The first unpaid call returns HTTP 402 with an x402 payment challenge — $0.25, USDC on Base, and the recipient.
  2. 2. Pay per call. Your x402 client signs the USDC payment and retries automatically — no API key, no account, no subscription. New to x402?
  3. 3. Read the result. HTTP 200 returns the computed values plus evidence-backed findings.

With the x402 fetch client (Node / TypeScript)

import { wrapFetchWithPayment } from "@x402/fetch";
import { privateKeyToAccount } from "viem/accounts";

const account = privateKeyToAccount(process.env.AGENT_WALLET_KEY);
const pay = wrapFetchWithPayment(fetch, account); // USDC on Base

const res = await pay("https://hermesplant.com/api/agent-services/dealanalyzer/analyze", {
  method: "POST",
  headers: { "content-type": "application/json" },
  body: JSON.stringify({
  "dcf": {
    "cashflows": [
      120,
      140,
      160,
      180,
      200
    ],
    "discountRate": 0.11,
    "exitMultiple": 9,
    "netDebt": 300,
    "shares": 100
  },
  "returns": {
    "cashflows": [
      -1000,
      0,
      0,
      0,
      0,
      2100
    ],
    "discountRate": 0.11
  },
  "waterfall": {
    "contributedCapital": 1000,
    "carryPercentage": 0.2,
    "catchUpPercentage": 1,
    "preferredRate": 0.08,
    "years": 5
  }
}),
});

const result = await res.json();

Inspect the 402 with curl

curl -i -X POST https://hermesplant.com/api/agent-services/dealanalyzer/analyze \
  -H "content-type: application/json" \
  -d '{"dcf":{"cashflows":[120,140,160,180,200],"discountRate":0.11,"exitMultiple":9,"netDebt":300,"shares":100},"returns":{"cashflows":[-1000,0,0,0,0,2100],"discountRate":0.11},"waterfall":{"contributedCapital":1000,"carryPercentage":0.2,"catchUpPercentage":1,"preferredRate":0.08,"years":5}}'
# → HTTP/1.1 402 Payment Required  (x402 challenge: price, USDC asset, Base network, recipient)
# → sign the USDC-on-Base payment and retry to receive HTTP 200

Prefer no wallet? Get a free API key (250 calls/mo) and send it as X-API-Key instead of signing an x402 payment — the same call, no crypto, ideal for looping over many records.

Prefer zero code? This endpoint is also exposed as a tool on the Hermes Plant MCP server, so an MCP-capable agent can call it with its own x402 wallet.
