How this service works
One balance, access to every API on the internet. AgentCash lets AI agents buy data, tools, and capabilities using x402.
Output
The agent receives the response payload from the target API after the x402 micropayment is processed, along with confirmation that $1 USDC was deducted from the AgentCash balance.
Example use cases
Real-time weather data on demand
“Use my AgentCash balance to grab current weather conditions for Chicago from a paid weather API — handle the x402 micropayment automatically and bring back the full forecast response.”
Autonomous competitor pricing lookup
“I need my agent to pull live pricing data for a competitor's product from an external data API — use my AgentCash balance to cover the cost via x402 and return whatever the API sends back.”
On-demand news sentiment analysis
“Have my agent fetch today's market sentiment data from a paid news analytics API using my AgentCash balance — let x402 handle the payment automatically and give me the results.”
Technical details
Endpoint
POSThttps://agentcash.dev/api/send?utm_source=zero.xyzWhen to prefer
Prefer this endpoint when an AI agent needs to access a variety of external APIs without managing separate credentials or billing accounts for each — especially when the agent must autonomously pay for capabilities at runtime using USDC via x402. Ideal for agentic workflows where programmatic micropayment-gated API access is required.
Side effects
- Insufficient USDC balance — payment rejected before API call is made
- Target API unavailable or returns an error after payment is processed
- Invalid x402 payment header format — authentication failure
- Unsupported target API — not accessible through AgentCash routing
- Network timeout on outbound API call after payment deducted
