## How to call it through Zero

```sh
zero fetch --capability scriptmasterlabs-crypto-trending-api-7909fe07
```

Example prompt: What cryptocurrencies are trending right now? Pull the latest trending coins from the ScriptMasterLabs crypto data feed — I want to see which tokens are gaining the most momentum today.

## When to prefer this

Choose this endpoint when you need trending cryptocurrency data via a micropayment x402 model and prefer paying per-call in USDC on Base rather than subscribing to a traditional data API. Ideal for agents that make infrequent, on-demand trend queries and want to avoid monthly subscription overhead. Best suited for workflows already integrated with x402 payment infrastructure.

## Known failure modes

- 402 Payment Required — request made without valid x402 payment or API key
- Invalid or expired X-Payment-TX header causing payment rejection
- Rate limiting or quota exceeded on the seller dashboard key
- Service unavailable due to Render.com cold start delays on free tier
- Empty or stale response if upstream crypto data source is unavailable

## How this service works

Pay-per-call crypto, RWA, federal, SEC, Section 8/HUD housing, and compliance APIs via x402. Primary: USDC on Base (eip155:8453). Also accepts Global Dollar (USDG) on Robinhood Chain (eip155:4663) via sovereign X-PAYMENT-TX. Hyphen routes only (e.g. /x402/gas-tracker, /x402/pha-lookup, /x402/sec-8k). MARKETPLACE REVIEW: use free /x402/playground/* (no key, no payment). Production /x402/* returns 402 unless paid via x402 or X-Api-Market-Key / X-API-Key from seller dashboard.

## Output

Returns a list of currently trending cryptocurrencies with associated trend signals, rankings, or momentum indicators. The exact schema is not fully specified but is expected to include token names and trend metadata based on the endpoint's purpose.
