## 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-prepaid-key-top-up-5-6d1bd71b
```

Example prompt: I want to top up my AgentFeed balance with the $5 prepaid key option so I can make repeated calls without dealing with per-call payments each time.

## When to prefer this

Choose this endpoint when you want to pre-fund AgentFeed access with $5 USDC and receive a reusable API key (X-AgentFeed-Key header) that grants half-price calls drawn from a balance, instead of paying x402 per call. Ideal for bots or agents making frequent AgentFeed calls that cannot handle per-call x402 payment flows, or when you want predictable spend management. Prefer $1 or $0.25 tiers for lighter usage, $20 tier for heavy usage.

## Known failure modes

- Payment not settled — response withheld until x402 payment confirms, may timeout if chain is congested
- Unsupported payment chain — x402 payment sent on a chain not supported by this endpoint
- Invalid payment amount — payment below or above the $5 USDC required price
- Network errors or endpoint downtime result in no key being issued

## How this service works

Crypto market data for AI agents (liquidations, funding, open interest, prices), Solana pre-trade checks, OFAC sanctions screening, scholarly papers, utilities and fixed-purpose language tasks (OCR, translate, summarize, extract, classify, prompt-injection check, transcribe). Paid per call in USDC over x402 on Solana, Base, Polygon, Arbitrum, Arc, Algorand, Optimism, Monad or Avalanche. High-frequency callers pay half price (minimum $0.0005) through batch-settlement (open a channel once, then off-chain vouchers) on Base, Polygon, Arbitrum or Circle Gateway nanopayments on Base, Polygon, Arbitrum, Arc. No API key or account is needed to pay per call. Bots that cannot pay x402 can buy a prepaid key once ($0.25, $1, $5, $20; page at /keys) and send it as X-AgentFeed-Key: each call then costs half the route price, minimum $0.0005, drawn from the balance (GET /api/keys/balance, free). A 30-day bot pass for /api/liq-feed is $25 flat, with nothing drawn per call (/api/keys/buy-pass).

## Output

Returns a JSON object confirming payment settlement, including the key prefix (e.g. 'Hk3mQ9xZ'), status ('active'), the credited amount ($5.00 USD), and the updated total balance. The response is only delivered after the x402 payment fully settles.
