stocks.metrics

Key fundamental metrics and 52-week price statistics for a US-listed company. Pass ticker; returns headline valuation, margin, and per-share figures — P/E, P/B, P/S, PEG, EV/EBITDA, gross/operating/net margins, ROE, ROA, current ratio, debt/equity, dividend yield, beta, 52-week high/low, and YTD/52-week price returns — plus the full Finnhub metric map under `metric`. Computed ratios you would otherwise derive yourself from raw filings. Market & fundamental data by Finnhub.

Overview

The metrics API is a pay-per-call stocks endpoint built for AI agents and autonomous software. Key fundamental metrics and 52-week price statistics for a US-listed company.

There is no signup and no API key. An agent (or any HTTP client) hits the endpoint, receives an x402 "402 Payment Required" challenge, signs a sub-cent USDC payment on Base or Solana, and retries — the data comes back on the paid request. That makes it a drop-in metrics data source for an agent tool-use loop, an MCP host, or a backend that needs stocks data on demand without onboarding to yet another vendor portal.

Code samples

cURLbash
# 1. Probe with no auth → 402 envelope with PaymentRequirements
curl -sS 'https://2s.io/api/stocks/metrics?ticker=example'

# 2. Sign + retry with PAYMENT-SIGNATURE:
curl -sS 'https://2s.io/api/stocks/metrics?ticker=example' \
  -H 'PAYMENT-SIGNATURE: <base64-json-payload>'

# Or use the canonical runner (handles probe → sign → retry):
#   EVM_PRIVATE_KEY=0x... node --env-file=.env.local \
#     --experimental-strip-types scripts/x402-pay.ts \
#     'https://2s.io/api/stocks/metrics?ticker=example'

console.log('endpoint:', result.endpoint)

// 1. Add @2sio/mcp to your MCP host config (Claude Desktop example below).
//    EVM_PRIVATE_KEY funds x402 payments per call.

FAQ

Do I need an API key to use the metrics API?
No. stocks.metrics is x402-native — there is no signup and no API key. Your client makes the call, receives a 402 with payment requirements, signs a USDC payment, and retries. Funds come from a wallet you control.
How much does the metrics API cost?
$0.0010 USDC per call, charged per request. There are no monthly fees, seats, or minimums — you pay only for the calls you make.
Can I try the metrics API for free first?
Yes. Add ?trial=1 (or the header X-2s-Trial: 1) to get a free real call per endpoint per hour, so you can verify the response shape before wiring payment.
Which networks and tokens are supported?
USDC on Base (via EIP-3009 transferWithAuthorization) or Solana (SPL transfer), using the open x402 payment protocol.
How do I call stocks.metrics from an AI agent or MCP host?
Use @2sio/sdk (TypeScript), 2sio (Python), or the @2sio/mcp server for any MCP host — each handles the probe → sign → retry loop for you. See the code samples on this page.
