## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability losbeto-pulse-name-to-age-estimation-pulse-check-0a9d2596
```

Example prompt: What's the estimated age for someone named Michael? Use the Losbeto pulse endpoint and pay per call — no API key needed.

## When to prefer this

Choose this endpoint when you need a quick, keyless, pay-per-call age estimation for a given name without setting up accounts or API keys, and when you also want to discover which other Losbeto market data endpoints are trending on the node. Not suitable for bulk name processing or high-accuracy demographic research.

## Known failure modes

- Missing required 'param' query parameter returns an error or empty result
- Invalid or unsupported name may return null or zero age estimate
- Payment failure via x402 (insufficient USDC balance or unsupported chain) blocks the call
- Upstream agify.io outage causes source unavailability
- Rate limiting or node-level throttling if USDC payment is not confirmed

## How this service works

OpenAI-compatible LLM gateway at $0.005/call — change base_url, pay in USDC. Plus pay-per-call market data: multi-oracle price consensus, sentiment, forex, equities, commodities, Brazil macro (BCB/B3) and crypto. No API keys, no accounts. USDC on Base, Solana, Algorand and Polygon via x402.

## Output

Returns a JSON object with a Unix timestamp, the estimated age (integer), the input param echoed back, the underlying source API (agify.io), a product description, a version string, the endpoint path, and an array of recommended next endpoints with their prices in USDC.
