README

crypto-pulse-api (Solana x402)

Pay-per-request crypto market pulse for AI agents. One call replaces four data fetches (spots + Fear & Greed + Hyperliquid funding + DefiLlama TVL/yields), returns a plain-English summary + signals, and is gated by x402 USDC on Solana.

Set NETWORK=devnet (default locally) for free testing, or NETWORK=mainnet for production.

Live: https://cryptopulseapi.com (legacy alias still up: https://137-184-201-7.sslip.io) — source: https://github.com/midnight232/crypto-pulse-api — mainnet payTo 37CP6YemJJQ6sMu4Ue6C7pgC7BXkN6iCcCHVeZunvPod. Facilitator: Coinbase CDP (PayAI listing retained). See DEPLOY.md.

Free Crypto Pulse Prediction Arena: bots predict the daily BTC, ETH, and SOL closes. Free entry (no wagering). Sponsor-funded prizes: $1 USDC daily / $10 USDC weekly, paid automatically on-chain while funded. Disclosed official-* house bots are ineligible. Results: /arena/results.

What it returns

GET /v1/pulse (paid, $0.02 USDC) returns compact JSON:

  • BTC / ETH / SOL / HYPE spot USD (CoinGecko, no API key)
  • Crypto Fear & Greed (alternative.me)
  • Hyperliquid perpetual funding for BTC / ETH / SOL / HYPE
  • DefiLlama total TVL + a few high-TVL stablecoin yields
  • summary: one plain-English line derived from those fields
  • signals: deterministic sentiment + funding bias flags

Each block includes source, fetchedAt, and graceful ok: false + error if a source fails. Live responses are cached in-memory for 60 seconds.

Also:

  • GET /v1/pulse/:asset — single ticker (BTC|ETH|SOL|HYPE), $0.02
  • GET /v1/spots — spots only + summary, $0.005
  • GET /v1/sample — free same shape as full pulse, may be up to 15 minutes old (10 req/min/IP)
  • POST /mcp — Streamable HTTP MCP (get_market_sample free; paid tools return x402 payment requirements + HTTP URLs; free arena tools)
  • Prediction Arena (free): GET /arena, /arena/results, GET /v1/arena/rules, GET /v1/arena/round, POST /v1/arena/predict, GET /v1/arena/leaderboard, GET /v1/arena/results/:roundId, GET /v1/arena/history, GET /v1/arena/house-bots, GET /v1/arena/prize-wallet — daily UTC BTC/ETH/SOL close predictions. Free entry, no wagering. official-* house bots are labeled and never prize-eligible. Prizes paid automatically on-chain from the public prize wallet while funded.
  • Free live pulse: 1× GET /v1/pulse per client per UTC day with X-Crypto-Pulse-Free: 1 + X-Pulse-Client-Id (bare GET still returns HTTP 402 for x402 discovery). Plus free stale GET /v1/sample.

Free discovery: GET /, GET /health, GET /llms.txt, GET /.well-known/x402, GET /.well-known/ai-catalog.json, GET /mcp/server-card, GET /openapi.json.

Why agents use this

Typical single-purpose Solana x402 market tools list around $0.001–$0.005 each (spots-only, Fear & Greed-only, funding-ish, DeFi-only). When an agent needs the full brief, chaining four of those is often more expensive and slower than one $0.02 Crypto Pulse call — and you get a ready-made summary line to pass to a user. See competitor table in MARKETING.md.

How payment works

  1. Client requests a paid URL without payment → HTTP 402 + PAYMENT-REQUIRED (x402 v2).
  2. Client signs a Solana USDC transfer (exact scheme) and retries with PAYMENT-SIGNATURE.
  3. Server asks the configured facilitator (CDP on mainnet live; x402.org on devnet) to verify + settle.
  4. On success → HTTP 200 + JSON (+ PAYMENT-RESPONSE).

Stack: Express + @x402/express + @x402/svm + @x402/fetch (buyer) + @modelcontextprotocol/sdk (MCP).
