Pulp.so positions itself as an βLLM tokens marketplace.β It does not develop its own models; instead, it acts as an API gateway that connects buyers, sellers, and model capacity. Buyers top up their accounts and send requests to gateway.pulp.so/v1, paying based on actual token usage. Sellers list available capacity and pricing, then receive payment according to real usage after requests are completed. The site emphasizes OpenAI/Anthropic compatibility, with integration requiring only a BASE_URL change.
Its core strengths are high-throughput routing with precise usage tracking, a real-time ledger, per-endpoint attribution for latency/tokens/cost, and seller-level analytics. The site shows example listings for models from Anthropic, OpenAI, Google, DeepSeek, Llama, and others, and supports toolchains such as the OpenAI SDK, Anthropic SDK, Vercel AI SDK, and Cursor. For agent use cases, it supports x402/HTTP 402 pay-per-call payments and agent-native wallets, making machine-to-machine micropayment settlement more natural.
For buyers, pricing is pay-as-you-go and determined by seller listings. Pulp.so claims there is no additional platform markup. Example pricing on the site shows some models discounted by 18% to 54% compared with list prices, and it mentions discounts of up to 60% off. For sellers, there are no listing fees or monthly fees; Pulp.so takes 9% of seller revenue from each request. It also supports hard budgets, a kill switch, threshold webhooks, and real-time spend dashboards, making it suitable for teams that need strict control over LLM costs.
The main advantages are low migration friction, a transparent ledger, billing based on real token usage, and improved pricing and availability through competition among multiple sellers. Automatic failover can also reduce the impact of a single seller key going down. The limitations are that it is still in early access, so the actual model pool, SLA, latency stability, and strength of seller vetting still need to be validated after launch. On data privacy, the site only mentions ledgers, audit attribution, and abuse protection; it does not disclose detailed policies on data retention, training usage, encryption, or compliance.
Pulp.so is a good fit for developers who already have LLM API usage and want to lower costs while keeping the OpenAI/Anthropic SDK experience, AI agent teams, and GPU/infrastructure providers looking to sell idle capacity. It is less suitable for enterprises with strict requirements around data compliance, fixed SLAs, or Chinese-language support. Availability from mainland China and payment support are not disclosed; Stripe and overseas APIs may introduce network and payment uncertainty. Domestic alternatives worth watching include SiliconFlow, Alibaba Cloud Bailian, and Volcengine Ark.
