# AgentOracle Spot Price by Ticker

> AgentOracle Spot Price by Ticker is a paid API for AI agents from aiagentoracle.ai, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-15).

Returns the latest USD spot price for a single on-chain crypto token identified by its ticker symbol, as a minimal 3-field payload optimized for high-frequency polling.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 aiagentoracle-ai-a67b1d47
```

Example prompt: What's the current USD spot price of ETH right now? Just give me the number and when it was last updated.

## When to prefer this

Prefer this endpoint when an agent needs only the current USD price of a single token and wants minimal payload overhead — ideal for high-frequency polling loops, trading bots, or any scenario where low latency and small response size matter more than full token metadata. Choose the full token-detail endpoint if you also need market cap, volume, or chain info.

## Known failure modes

- 404 returned for unknown or unsupported ticker symbols
- priceUsd may be null if ingestion data is temporarily unavailable
- Payment required (402) if x402 payment header is not included or insufficient
- Symbol case issues if client sends unexpected formatting (though API is case-insensitive)
- Stale asOf timestamp if ingestion pipeline is delayed

## How this service works

AgentOracle: latest spot price for a single token by ticker symbol — minimal payload (`{ symbol, priceUsd, asOf }`) optimised for high-frequency polling agents. Case-insensitive symbol; returns 404 for unknown symbols.

## Output

A minimal JSON object with three fields: `symbol` (the ticker as stored), `priceUsd` (current spot price as a number, or null if unavailable), and `asOf` (ISO 8601 datetime of the price snapshot). Returns HTTP 404 for unrecognized ticker symbols.
