DeepSeek R1 reasoning model API: pay per call, no API key

$0.01 per call · failed calls are never charged · no account or API key needed

Chat with DeepSeek's R1 reasoning model distilled into Qwen 32B (MIT) through one paid HTTP call: send a prompt and an optional system prompt, get the answer, up to 2,048 output tokens; its reasoning is removed from the answer. Also reachable as model "deepseek-r1" on the OpenAI-compatible /v1/chat/completions. No account or provider key. Use when an agent wants this model by name.

Request

Over HTTP, with a card key from /credits:

curl -H "Authorization: Bearer adt_…" "https://agent-data-tools.revmesh2074.workers.dev/ai/model/deepseek-r1?prompt=Explain%20x402%20in%20one%20sentence."

Without a key, the same URL answers 402 Payment Required with x402 and MPP terms, so an agent with a wallet pays per call in USDC (Base, Polygon, Arbitrum or Solana over x402; Base or Tempo over MPP) and retries.

Example result

{
  "model": "@cf/deepseek-ai/deepseek-r1-distill-qwen-32b",
  "response": "x402 lets software pay for an HTTP request with a stablecoin by answering a 402 Payment Required challenge."
}
