Live crypto ticker momentum stats (mentions, velocity, acceleration) via x402 micropayment.
What it does
Naiko x402 API exposes a pay-per-call endpoint at /data/momentum that returns live ticker statistics including mention counts, velocity (mentions per minute), acceleration, and lifecycle-stage classification. The endpoint is part of a broader "crypto intelligence" service and is gated by the x402 protocol on Base (EIP-155:8453), accepting USDC payments.
Each call costs 5,000 base units of USDC (6 decimals), which equals $0.005 (half a cent). Payment is handled via Permit2 with gas sponsorship, smart-wallet support, and ERC-4337 account abstraction. The response MIME type is application/json. No OpenAPI schema or detailed documentation is available beyond the endpoint's self-description in the x402 challenge and the provider's landing page.
Because no formal docs, request/response schemas, or usage examples are published, the exact query parameters (e.g., how to specify a ticker symbol) and response shape must be discovered by making a paid call. The endpoint is confirmed live (HTTP 402 challenge returned successfully).
Capabilities
Use cases
- —Monitor real-time social mention velocity for a cryptocurrency ticker
- —Detect early-stage momentum shifts in token buzz before price moves
- —Classify a token's lifecycle stage (emerging, trending, declining) for trading signals
- —Feed mention acceleration data into an automated trading or alerting pipeline
- —Enrich a crypto dashboard with live social-signal metrics
Fit
Best for
- —Agents or bots that need on-demand crypto social-signal data without subscriptions
- —Developers building momentum-based trading strategies
- —Low-volume, pay-as-you-go crypto analytics consumers
Not for
- —Users who need historical time-series data (no evidence of historical endpoints)
- —Non-crypto social-media analytics
- —High-volume bulk data pipelines where per-call pricing may add up
Quick start
curl -i https://capable-grace-production-ab1c.up.railway.app/data/momentum
# Returns HTTP 402 with x402 payment challenge.
# Complete the USDC payment on Base to receive the JSON response.Endpoint
Quality
The endpoint is confirmed live via a valid x402 402 challenge, and the resource description is informative. However, there is no OpenAPI schema, no documentation, no request/response examples, and no way to determine query parameters without paying. This is effectively a stub listing.
Warnings
- —No OpenAPI or formal documentation available; /docs, /api, /pricing, /README all return 404.
- —Request parameters (e.g., how to specify a ticker) are unknown — must be discovered by making a paid call.
- —Response schema is undocumented; the only hint is the MIME type (application/json) and the textual description in the x402 challenge.
- —Provider landing page is minimal; no terms of service, rate limits, or SLA information found.
