For work that outlives one HTTP response. You submit steps, each an HTTP request against a public address; the job is acknowledged at once and runs in the background, and the collected results are POSTed to your callback URL when finished. Every step reports its status, timing, response headers and body up to 256 KB, and a failing step never aborts the others. Price is 0.003 USDC per step, quoted before payment.

Works out what a call would cost. Give either the text itself or a token count, plus the expected output length, and get input, output, cache-read and cache-write cost per model with the total. Token counts derived from text are estimates from character and word statistics, not a tokeniser, and typically land within about 15 percent — where an exact count matters, count with the vendor tokeniser.

Price is 0.004 USDC per started megabyte, quoted before payment from the size you declare. Actions: store, status, delete.
