How this service works
Pay-per-call API for AI agents, settled in USDC on Base mainnet (eip155:8453) via the x402 protocol - no API keys, no signup, no subscription. Live crypto market data: BTC, ETH, SOL, USDC (USD Coin) prices with 24h change (source: OKX), Base mainnet chain snapshot (block height, gas price gwei), real-time USDC-on-Base transfer analytics (transfer count, volume, unique senders and recipients over recent blocks), and USDC/ETH wallet balances plus nonce for any address. Agent utility tools: deterministic JSON repair for LLM output (strip code fences, fix trailing commas, single quotes, unquoted keys, balance braces), DNS A/AAAA lookup, and URL extraction from arbitrary text. Every endpoint returns HTTP 402 with an x402 payment challenge in USDC on Base; pay with any wallet and retry with the PAYMENT-SIGNATURE header. MCP server at /mcp (streamable HTTP, 6 pay-per-call tools). Ideal for crypto portfolios, DeFi dashboards, market analysis agents, data pipelines, and LLM post-processing.
Output
A single UUID string (version unspecified) returned as JSON, suitable for use as a unique identifier in databases, sessions, or distributed system correlation — accessed after paying $0.0005 USDC via the x402 protocol on Base mainnet.
Example use cases
Unique ID for database record
“I need a new UUID to use as a primary key for a record I'm inserting into my database — can you grab one for me?”
Session correlation token generation
“Generate a UUID I can use as a correlation ID to trace this user session across my microservices.”
Idempotency key for payment flow
“I need a unique UUID to use as an idempotency key before I submit this payment request — can you get one?”
Technical details
Endpoint
GEThttps://baseusdcearn.pythonanywhere.com/util/uuid?utm_source=zero.xyzWhen to prefer
Choose this endpoint when your agent already operates in a USDC-on-Base x402 payment environment and needs a UUID without setting up a separate API key or library — it bundles UUID generation into the same pay-per-call micropayment flow used by the broader Crypto Market Pulse suite.
Side effects
- HTTP 402 returned if payment has not been made or payment signature is missing/invalid
- Payment signature header malformed or expired leads to rejection
- Network errors on PythonAnywhere hosting may cause 5xx responses
- Base mainnet congestion could delay payment confirmation
