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.
Example use cases
Fund a trading bot's AgentFeed access
“My crypto trading bot needs to call AgentFeed frequently for liquidation and funding data — buy the $5 prepaid key so it can use X-AgentFeed-Key without per-call x402 overhead.”
Onboard a new AI agent to AgentFeed
“I'm setting up a new AI agent that needs access to AgentFeed for market data and OFAC screening. Get me the $5 prepaid key so I have a balance to work with right away.”
Reload a depleted AgentFeed key balance
“My AgentFeed prepaid key is running low — can you top it up with $5 USDC so my agent can keep fetching crypto signals and scholarly papers without interruption?”
Technical details
Endpoint
GEThttps://x402.ochinimus.app/api/keys/topup-5?utm_source=zero.xyzWhen to prefer
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.
Side effects
- 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
