How this service works
Live X/Twitter read API plus Base market intel for AI agents: profiles, search, timelines, replies, followers; Base gas, spot prices, token meta/pairs, Base token verdict cards, trending, DefiLlama TVL, wallet intel, x402 probe and text utilities. REST + MCP. Pay per call in USDC via x402 on Base and Solana — no API keys. Free upstream data + local scoring.
Output
Returns a JSON object containing the HTTP response details from the probed URL, including status code, headers, and any x402-specific payment metadata (e.g. payment address, amount, currency). Useful for determining whether an endpoint is live, what payment scheme it uses, and whether access is gated.
Example use cases
Verify x402 payment gate on endpoint
“Probe https://some-agent-api.example.com/v1/report with a GET request and tell me if it returns a 402 Payment Required and what payment details it advertises.”
Check if a URL is live and accessible
“Can you do a HEAD probe on https://x-data-gateway.annushka1190.workers.dev/v1/health to confirm it's responding and show me the response headers?”
Inspect API endpoint before integrating
“Before I integrate with https://partner-api.example.com/feed, can you probe it with a GET and tell me what status code and headers come back?”
Technical details
Endpoint
GEThttps://x-data-gateway.annushka1190.workers.dev/v1/x402/probe?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to programmatically inspect an HTTP URL's response metadata — especially to detect x402 payment requirements — without a browser or external HTTP client. Ideal for agents discovering whether a target API is x402-enabled, checking liveness, or reading headers before committing to a full API integration. Not suitable for POST/PUT/PATCH operations or for fetching large response bodies.
Side effects
- Invalid or non-HTTPS URL returns a validation error
- Target URL is unreachable or times out, returning a connection error
- URL returns an unexpected non-HTTP response
- Probe itself fails to pay the $0.005 USDC x402 fee, blocking the call
- Method not in allowed enum (only GET/HEAD/DELETE supported)
