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).","url":"https://x402.ochinimus.app/api/keys/topup-5?utm_source=zero.xyz","method":"GET","headers":{},"bodySchema":{"type":"object","properties":{"required":{"type":"string"},"properties":{"type":"string"}}},"responseSchema":{"type":"json","example":{"data":{"note":"credited when this payment settled; this response is only delivered after it did","prefix":"Hk3mQ9xZ","status":"active","credit_usd":5,"balance_usd":5.043},"paid":true,"tool":"topup_key_5"}},"example":null,"exampleRequest":null,"tags":["x402"],"displayCostAmount":"5","displayCostAsset":"USDC","priceDynamic":false,"priceHint":null,"priceStatus":"priced","priceSource":"probe","requiresHandshake":false,"reviewCount":0,"rating":{"score":"0.00","successRate":"0.00","reviews":0,"stars":null,"state":"unrated"},"availabilityStatus":"unknown","priceObserved":null,"sessionDeposit":null,"pricing":{"kind":"static","summary":"$5/call","primary":{"kind":"static","protocol":"x402","network":"base","amountUsd":"5","per":"call","confidence":"exact"},"accepted":[{"kind":"static","protocol":"x402","network":"base","amountUsd":"5","per":"call","confidence":"exact"}]},"paymentMethods":[{"uid":"pm_yWISm7CuolYioqSFykOGn","protocol":"x402","methodType":"crypto","chain":"base","mode":"charge","costAmount":"5","costPer":"request","priority":0,"asset":"EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v","unit":"request","depositMicros":null,"planRef":null}],"brandName":null,"brandSlug":null,"brandBaseUrl":null,"brandDocsUrl":null,"whatItDoes":"Purchases and credits a $5 USDC prepaid API key for use with AgentFeed endpoints, eliminating the need for per-call x402 payments","exampleAgentPrompt":"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.","exampleUseCases":[{"title":"Fund a trading bot's AgentFeed access","prompt":"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."},{"title":"Onboard a new AI agent to AgentFeed","prompt":"I'm setting up a new AI agent that needs access to AgentFeed for market data and OFAC screening.
