# Paid calls

Claude Code makes no paid call before a row exists for it in this table.

| Date | Service | Purpose | Max calls | Max cost (USD) | Approved by |
|---|---|---|---|---|---|
| 2026-10-20 | TypeSafe JEV API | All JEV calls of the study, within the free credit for a new user (D44); calls left under the 7,000-call cap of D26 | 2446 | 5 | fmm |
| 2026-10-21 | TypeSafe JEV API | Fair comparison: description loops, checks, calibration and test runs (design X17, D84) | 50000 | 20 | fmm |

## Call logs

Each service has one log: `<service>-calls.csv`. The columns are:

`time_utc,call_id,purpose,model,request_id,status,latency_ms,input_tokens,output_tokens,cost_usd`

## Paid calls before the record

The record started after the experiments (D7). The paid calls before it were approved in the chat, not in this table. There is no per-call log for them (open item O2).

- Service: TypeSafe JEV API (`jev-1.13.0`). Calls made: 4,554, on 2026-10-20.
- Approvals in the chat: batch 1 with 600 calls (D4), a cap of 1,000 calls (D10), a cap of 5,000 calls (D16), and a cap of 7,000 calls (D26).
- Estimated cost: about USD 0.52 (12.3 million input tokens at USD 0.042 per million). The estimate multiplies the calls of each batch by the input tokens measured for that kind of request. These calls count against the USD 5 budget above, so about USD 4.48 remains.
- Clef-Flash (D34) and CLIP ran on a local GPU. They had no API cost.

## Paid calls after the budget row

- 2026-10-20, about 18:40 UTC: 100 JEV calls, made by mistake. A test of a new guard in `scripts/optimize_jev.R` was meant to stop before any call, but Rscript reloaded the key from `.Renviron`. The run used the default microstructure settings, so it repeated the baseline (BA 0.54, AUC 0.789, against 0.55 and 0.803). Estimated cost: about USD 0.011. There is no per-call log (open item O2).
- Totals: 4,654 JEV calls, about USD 0.53. Left under the budget row: 2,346 calls and about USD 4.47.

## Calls of the fair comparison

Budget row of 2026-10-21 (D84). Each call has a row in `typesafe-calls.csv`. The cost is an estimate: input tokens times USD 0.042 per million.

| Step | Purpose prefix | Calls | Failed | Input tokens | Estimated cost (USD) |
|---|---|---|---|---|---|
| Checks before the loops | fair check | 4 | 0 | 6,448 | 0.0003 |
| Description loops (design set) | fair design | 1,248 | 0 | 2,422,368 | 0.10 |
| Calibration runs (set C) | fair calibration | 1,170 | 0 | 2,292,808 | 0.10 |
| Test runs (one time) | fair test | 6,012 | 0 | 12,622,200 | 0.53 |
| Total | | 8,434 | 0 | 17,343,824 | 0.73 |

- Left under the budget row: 41,566 calls and about USD 19.27.
- Clef-Flash and CLIP ran on a local GPU. They had no API cost.
