| Free tier | no free tier. Four paid tiers: Flash Mini 400M Credits at USD 6.99 a month, Flash Plus 1,600M at USD 9.99, Flash Pro 8,000M at USD 29, Flash Max 40,000M at USD 99. Credits convert at approximately USD 1 = 7M Credits unit mixed; metered on request-count; the allowance is denominated in Credits, and the page states the conversion. 1,600M Credits at approximately 7M Credits per USD is about USD 228.6 of model usage for USD 9.99, which is the basis of the price-per-token comparison in docs/coding-subs/paid/under-20.md |

| Price | none stated |
| Per-object cap | not applicable: a subscription meters usage, not objects |
| Retention | monthly Credits are cleared at the end of the month and do not roll over; booster-pack Credits expire on their own 30-day cycle (30 days) |
| Egress | not applicable: the vendor serves the inference |
| Identity | card a paid subscription, payable by Stripe or redeemed from the account balance |
| Limits |
booster packs are available to active subscribers only and run on their own 30-day cycle: Small USD 6.99 for 400M Credits, Large USD 9.99 for 1,600M |
| Binding | retention-clamped the monthly clearance binds before any request rate does, because there is no request rate to bind: an unused allowance is lost at month end rather than carried |
| Interface | rest, cli two documented Base URLs: https://api.stepfun.ai/step_plan for the Claude Code and Anthropic SDK shape, and https://api.stepfun.ai/step_plan/v1 for OpenAI SDK Chat Completions. The page states these are client configuration URLs and not full request URLs |
| Tooling | Claude Code, the Anthropic SDK, the OpenAI SDK, Trae, Cursor and OpenClaw are named on the page as supported clients |
| Composes with | pairs with any Anthropic-shaped or OpenAI-shaped agent; the monthly Credit allowance is the scarce link, and it is spent by the Step Plan Base URL rather than by the standard API channel, which has its own separate quota |

| Notes | This record carried verdict: trial-only and confidence: unverified until 2026-10-22T04:14Z, on a 396-byte shell from www.stepfun.com/pricing. At USD 9.99 for 1,600M Credits, or about USD 228.6 of model usage, this is the cheapest plan in the market per unit of work and the strongest counter-example to the topic's 'nothing under USD 20 carries a usable allowance' conclusion. |
| Evidence rung | documented the four tiers, the Credit allowances, the conversion rate, the two Base URLs and the no-rate-limit statement are all quoted from the vendor's own documentation page, read 2026-10-22 at 200 with 9444 bytes. No subscription was bought, so the allowance is the vendor's number and not a measurement. |

Corrections
- 2026-10-22 StepFun's USD 9.99 tier was live, and a month-old date error hid the cheapest plan in the market
