# AgentFeed Multi-Asset Spot Price

> AgentFeed Multi-Asset Spot Price is a paid API for AI agents from x402.ochinimus.app, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-02).

Returns the current USD spot price for SOL, BTC, or ETH using a fixed fallback chain (Coinbase → Kraken → Pyth Hermes), including the serving venue and Pyth confidence interval when applicable.

## 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 agentfeed-multi-asset-spot-price-759d0aa3
```

Example prompt: What's the current spot price of SOL right now, and tell me which venue served it?

## When to prefer this

Choose this endpoint when an agent needs a spot price for SOL, BTC, or ETH without hardcoding a specific exchange. The automatic fallback chain (Coinbase → Kraken → Pyth) maximizes uptime and the included source field lets downstream logic know which venue served the price. Prefer this over single-source endpoints when resilience matters or when Pyth confidence intervals are useful for risk checks.

## Known failure modes

- Unsupported symbol requested — endpoint returns an error with the list of supported symbols (SOL, BTC, ETH)
- All upstream sources (Coinbase, Kraken, Pyth) unavailable — lookup fails with upstream error
- Payment not provided or insufficient — x402 payment required response returned
- Stale Pyth data — publish_time may be behind real-time by a few seconds during network congestion

## How this service works

Spot price: the price, the venue that actually served it, and a Pyth confidence when Pyth served. Use when you need to answer: What is the spot price, without picking a venue? Coinbase, then Kraken, then Pyth Hermes. Serves SOL, BTC and ETH; anything else is declined.

## Output

A JSON object containing: the resolved USD price as a number, the symbol queried, the source/venue that served the price (e.g. 'coinbase', 'kraken', 'pyth'), and optionally a Pyth confidence value and publish_time when Pyth was the serving source. Also includes a 'supported' array listing accepted symbols and a 'paid' boolean.
