Generate images via OpenAI DALL-E, settled per-call on Tempo L2 (pathUSD).
What it does
This MPP (Micropayment Protocol) endpoint proxies OpenAI's DALL-E image generation API through the Tempo payment network. The intended use is to POST image generation requests to the /v1/images/generations path, mirroring the standard OpenAI API contract, with payment handled automatically via Tempo's pathUSD settlement layer.
However, during probing the endpoint returned 404 on both HEAD and GET requests, and no 402 payment challenge was captured. This is notable because MPP endpoints are expected to return a 402 with a WWW-Authenticate: Payment header to advertise their pricing and payment method. The 404 may indicate that the endpoint only responds to POST requests (which is consistent with OpenAI's image generation API design), or it may indicate the endpoint is currently offline or misconfigured. No documentation, OpenAPI schema, pricing information, or examples were recoverable from the crawl — every path on the origin returned 404.
Based on the existing Bazaar listing, this endpoint is part of a broader OpenAI proxy suite on Tempo that also covers chat completions, embeddings, and audio. Without a captured payment challenge, pricing details (per-image cost in pathUSD) cannot be confirmed. Users should attempt a POST request with a standard OpenAI-compatible body to determine current availability and pricing.
Capabilities
Use cases
- —Generating images from text prompts without an OpenAI API key, paying per-call via Tempo
- —Integrating AI image generation into agent workflows with crypto-native micropayments
- —Prototyping visual content creation with pay-as-you-go pricing
Fit
Best for
- —Agents or apps that need on-demand image generation with crypto settlement
- —Developers without OpenAI accounts who want per-call access to DALL-E
- —Workflows requiring programmatic text-to-image without subscription commitments
Not for
- —High-volume production image generation where a direct OpenAI subscription is more economical
- —Use cases requiring guaranteed uptime — endpoint liveness is currently unconfirmed

Quality
The endpoint returned 404 on all probe methods and no 402 payment challenge was captured. All crawl pages returned 'Not Found'. No schema, pricing, or documentation is available. The listing is essentially a stub based on the Bazaar record title and description.
Warnings
- —Endpoint returned 404 on HEAD and GET — no MPP 402 challenge captured; liveness unconfirmed
- —All crawl paths (root, /docs, /api, /pricing, /README) returned 404
- —Pricing is unknown — no payment challenge was captured to determine per-call cost
- —The endpoint may only respond to POST requests, which the probe did not attempt
