Billing — no fee to add credits, 5.5% included in every debit
Adding credits no longer carries a fee. Instead, every debit — each call, batch, reservation, daily storage charge and flat rate — includes a 5.5% fee on the provider’s cost, and every price the gateway serves already includes it: the catalog’s price, priceLabel and expectedMicro, SKILL.md, the MCP tools, and the per-token pricing on GET /inference/v1/models and GET /huggingface/v1/models. GET /v1/catalog and GET /v1/catalog/{id} now carry a top-level callFeeBps (550 = 5.5%). Calls billed to your own provider key are not debited, so they carry no fee. New accounts get $1 of credit.
