OpenAI Responses API (Llama / GPT-OSS, pay-per-call)
x402
OpenAI Responses API (Llama / GPT-OSS, pay-per-call) is a paid API for AI agents from agent-data-tools.revmesh2074.workers.dev, paid per call via x402, $0.01/call (dynamic — varies by input), status unknown (last checked 2026-10-22).
Generates a single non-streaming text completion using the OpenAI Responses request shape, served by Llama 3.1 8B (default, $0.003), Llama 3.3 70B, or gpt-oss-120b ($0.01).

How this service works
OpenAI Responses request shape: input (a string or a list of role/content items), optional instructions, max_output_tokens and temperature; one completed message comes back in output (plus output_text). Served by the same models and prices as /v1/chat/completions: $0.01 by default, $0.01 with model "llama-3.3-70b" or "gpt-oss-120b". No streaming, no tools. Point an OpenAI SDK at https://agent-data-tools.revmesh2074.workers.dev/v1 with an x402 or MPP fetch wrapper. Failed calls are never charged.
Output
Returns a response object following the OpenAI Responses shape, containing an 'output' array with the completed message and a top-level 'output_text' field with the raw text. No streaming chunks — one complete response per call. Model used and token usage metadata may also be included.
Example use cases
Quick Q&A with cheap LLM
“Use the default Llama 3.1 8B model to answer this question in under 200 tokens: 'What is the capital of Australia and what is it known for?'”
Instruction-following with system prompt
“I need you to act as a JSON formatter. Use the gpt-oss-120b model with the system prompt 'You only output valid JSON, no explanation' and ask it to convert this sentence into a JSON object: 'Alice is 30 years old and lives in Berlin.'”
Creative writing at low temperature
“Generate a short two-sentence product tagline for a coffee brand called Morning Bloom using the Llama 3.3 70B model, temperature 0.2, max 80 tokens.”

Endpoint
GEThttps://agent-data-tools.revmesh2074.workers.dev/v1/responses?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a cheap, stateless, non-streaming single-turn text completion via the OpenAI Responses API shape, especially if your agent is already using an OpenAI SDK and you want to point it at a pay-per-call alternative with no account setup. Prefer the default Llama 3.1 8B model at $0.003 for high-volume or cost-sensitive tasks; switch to Llama 3.3 70B or gpt-oss-120b at $0.01 for better reasoning quality. Not suitable for streaming, tool-calling, function-calling, or multi-turn stateful conversations.
Side effects
- Missing required 'input' field returns a validation error and no charge
- Setting stream:true returns an error (streaming is not supported)
- max_output_tokens exceeding 1024 triggers a schema validation error
- Invalid model name may fall back to default or return an error
- Payment failure (insufficient x402 balance or bad credentials) results in a 402 response and no charge
- Network timeout on the Cloudflare Worker edge may return a 5xx with no charge
