# Agentic Payments Ecosystem Tracker — Micro Tier Dataset

> Agentic Payments Ecosystem Tracker — Micro Tier Dataset is a paid API for AI agents from data-vending.869biz.com, paid per call via x402, $0.002/call, status unknown (last checked 2026-09-15).

Downloads a micro-tier JSON dataset tracking the agentic payments ecosystem, paid via x402 USDC micropayment with no API key required.

## Facts

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 agentic-payments-ecosystem-tracker-micro-tier-dataset-0d826aab
```

Example prompt: Fetch me the micro-tier agentic payments ecosystem tracker dataset — pay with base-usdc and use the quote ID I got from the quote endpoint.

## When to prefer this

Choose this endpoint when an AI agent needs a lightweight, no-signup snapshot of the agentic payments ecosystem and can pay $0.002 USDC via x402 on Solana or Base. It is ideal for agents that need structured, human-curated data about AI payment rails without OAuth or API key setup, especially when building reports or enriching context about the x402/USDC agentic payment landscape.

## Known failure modes

- Invalid or expired quote_id returns an error rejecting the download
- Unsupported rail_id value (not solana-usdc or base-usdc) causes a validation error
- Payment not confirmed on-chain leads to 402 Payment Required response
- Dataset temporarily unavailable returns a 503 error
- Malformed request body causes a 400 Bad Request

## How this service works

HTTP-native dataset vending for autonomous AI agents. No signup, no API key — discover, pay USDC via x402, get clean JSON. Human-designed data with provenance and conservation revenue share.

## Output

A JSON object with the dataset SKU ('agentic_payments.ecosystem_tracker.micro.v1'), tier ('micro'), a list of ecosystem items each with a title and source count, the as_of_date of the data, an item_limit (2 items in micro tier), and a pointer to upgrade to the 'probe' tier for more data.
