How this service works
On-demand AI responses backed by autonomous ICP canisters. Submit a prompt, get an answer — redundant infrastructure, pay-per-query, no account required.
Output
Returns an AI-generated text answer to the submitted prompt, produced by autonomous ICP canisters. The response reflects the agent's reasoning on the input prompt and is returned directly after the pay-per-query USDC transaction is processed.
Example use cases
On-demand research answer without signup
“I need a quick AI-generated explanation of how zero-knowledge proofs work — use the a2apay agent endpoint, pay the small per-query fee, and give me the answer without me needing to create an account anywhere.”
Autonomous agent subtask delegation
“I'm building an automation pipeline — for this step, submit the prompt 'summarize the key risks of algorithmic trading in three bullet points' to the a2apay agent service and return whatever it comes back with.”
Crypto-native AI query for dApp
“My dApp needs a one-off AI response: ask the agent 'what is the current role of ICP canisters in decentralized AI?' and bring back the answer, paying the micropayment fee per query.”
Technical details
Endpoint
POSThttps://a2apay.io/api/agent-service?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a one-off AI-generated response without account creation or subscription, especially in crypto-native or agent-to-agent workflows where micropayment via USDC (x402 protocol) is acceptable. Prefer it over OpenAI or Anthropic APIs when decentralized, accountless, pay-per-query inference is required, or when operating within ICP/Web3 ecosystems.
Side effects
- Insufficient payment — query rejected if USDC micropayment not fulfilled
- Malformed body — missing required 'type', 'method', or 'bodyType' fields causes validation error
- Canister unavailability — ICP infrastructure outage may delay or fail response
- Invalid bodyType enum — only 'json', 'form-data', or 'text' accepted
- Prompt too long or malformed — agent may return an error or truncated response
