POST /sell/api/v1/offers

Publish a simple capacity offer. The API derives seller identity from X-Seller-API-Key and translates the offer into an ask on the authoritative Market book.

Advanced Market clients can use the raw /v1/sellers/{id}/asks operation beneath the /market/api base instead.

Request

field	type	notes
`model`	string	Must be in the seller's supported models
`region`	string	Required concrete region; `any` is rejected
`price_per_million_tokens`	decimal string	Strictly positive
`quantity_tokens`	integer	Strictly positive
`valid_for_seconds`	integer	Required positive lifetime
`tenor`	string	Optional supported forward delivery window

curl -s https://aispotmarket.com/sell/api/v1/offers \
  -H "X-Seller-API-Key: sk-seller" \
  -H "Content-Type: application/json" \
  -d '{"model":"gpt-4","region":"us-east","price_per_million_tokens":"10","quantity_tokens":1000000,"valid_for_seconds":300}'

The response contains the offer id, normalized model/region, price per million, original and remaining token quantity, validity, and optional tenor. Cancel the unfilled remainder with DELETE /sell/api/v1/offers/{id}.

Use the advanced Market OpenAPI when you need raw ask primitives or per-1,000-token book prices.
