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
Returns a UUID string as part of a JSON response, suitable for use as a unique identifier in agent workflows, deduplication, or request tagging. The call is gated by an x402 HTTP 402 payment challenge requiring $0.0005 USDC on Base mainnet before the UUID is returned.
Example use cases
Unique ID for agent pipeline deduplication
“I need a fresh UUID to tag this batch job so I can deduplicate results later — grab one from the CryptoPulse utility endpoint, paying in USDC on Base.”
Correlation ID for DeFi dashboard requests
“Generate a UUID I can use as a correlation ID to trace this market data request through my DeFi dashboard logs.”
Request token for LLM workflow tagging
“Get me a unique identifier to attach to this LLM output so I can track it through my post-processing pipeline.”
Technical details
Endpoint
GEThttps://cryptopulse.pythonanywhere.com/util/uuid?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight UUID generation utility within an agent pipeline that already uses the CryptoPulse x402 ecosystem for crypto market data or USDC analytics, and you want a single pay-per-call model without API keys or subscriptions. Not ideal if you just need a UUID locally — standard libraries (uuid4) are free and instant. Best when bundled with other CryptoPulse calls in the same workflow.
Side effects
- HTTP 402 returned if payment signature header is missing or invalid — agent must pay with USDC on Base and retry with PAYMENT-SIGNATURE header
- Network timeout if PythonAnywhere host is slow or unavailable
- Unexpected non-JSON response if server encounters an unhandled error
- Payment confirmation delay if Base mainnet is congested
