The product

Crypto Market Briefing

An XRP-focused market briefing API that also covers major coins. Built for people and agents who need a concise, machine-readable snapshot in a single request.

Written Summary & Sentiment

A deterministic summary of the price move, plus a bullish, neutral, or bearish sentiment label and score derived from the data and headline keywords. No paid LLM in the loop.

XRP Ledger Signals

For XRP, the briefing scans recent validated ledgers for network activity versus a short typical average, and flags large payments of at least 1 million XRP when they appear.

ETF, SEC & Regulatory Flags

Headlines are tagged when titles mention ETF, SEC, or other regulatory keywords, so agents can spot those stories without extra parsing.

Multi-Coin Coverage

Pass a CoinGecko id or common symbol — btc, eth, sol, xrp, and the other supported assets listed below. Ledger whale signals are included only for XRP.

Machine-Ready JSON

Structured output with price, market cap, volume, summary, sentiment, headlines, and XRP signals when applicable. No HTML to scrape.

$0.02 USDC

No API Keys or Accounts

Pay per call in USDC on Base with the x402 protocol. There is no signup, subscription, or API key to manage.

Endpoints

Call the API

Two paid routes, same price. Free routes at /, /health, and /info describe the service without a charge.

GET
https://api.cryptobroski.com/briefing?coin=btc

Multi-coin briefing. Replace btc with any supported symbol or CoinGecko id. Ledger signals are included only when the coin is XRP. Defaults to XRP if coin is omitted.

GET
https://api.cryptobroski.com/xrp/briefing

XRP-specific route. Always includes XRP Ledger activity and large-transfer signals, along with price, summary, sentiment, and headlines.

Example call

npx awal x402 pay "https://api.cryptobroski.com/briefing?coin=xrp"

This is the documented Agentic Wallet / Agentic.Market command for paying an x402 endpoint in USDC on Base. Authenticate and fund the wallet first. Other x402 clients work the same way: an unpaid request returns HTTP 402; a signed payment is settled; the briefing JSON comes back.

Protocol

How it works

x402 is an HTTP 402 payment standard. The client pays a small USDC amount on Base, then receives the briefing. No API key is issued.

01

Request

Call a paid route. If no payment is attached, the API returns HTTP 402 Payment Required with the price, pay-to address, network, and asset.

02

Pay USDC on Base

An x402 client signs a $0.02 USDC authorization on Base (eip155:8453). The facilitator settles the transfer; you do not need ETH for gas on the standard exact flow.

03

Get the data

The same request returns HTTP 200 and the briefing JSON. The service is listed on the x402 Bazaar and discoverable via Agentic.Market.

Learn more at x402.org and agentic.market.

Pricing

Simple pay per call

$0.02 USDC / call

Same price on every paid route. No subscription, no monthly minimum, and no API key. Payments are USDC on Base via x402.
