26 Oct 2026

Anthropic Messages API compatibility. POST /v1/messages works with Anthropic SDKs: base_url="https://pay.trustai.center", tai_ key as api_key (sent as x-api-key; Bearer also accepted). Supports system, text content blocks, max_tokens, temperature, top_p, stop_sequences and stream (Anthropic SSE events). Same models, prices, spend controls and x402 pay-per-request (402 without a key). Anthropic-style ids like claude-sonnet-4-6 resolve to the catalog id. Tool use and images are not supported on this endpoint yet. Docs.
Bigger catalog. The daily model sync now exposes 411 models: 307 servable chat models, plus image, video and audio models listed for discovery (/v1/models?include=discovery). Every price is at most 2% above the model maker's list price.
Guide prices refreshed. DeepSeek V4.1 Flash is now $0.3 in / $1.2 out per 1M tokens (the maker's new list price); guide tables updated. The dated snapshot deepseek-v4.1-flash-1017 stays at $0.15 / $0.6. Live prices are always in /v1/models.
Transparent trending. /v1/trending and MCP list_trending now return a ranking field (usage_24h or curated) so agents know how the list was built.

Launch: OpenAI-compatible /v1/chat/completions and /v1/models, streaming.
x402 pay-per-request in USDC on Base; settlement only after a successful completion.
Remote MCP server at /mcp (list_models, list_trending, create_topup, verify_topup, claim_topup, chat_completion, balance, usage, spend controls, stats).
Prepaid tai_ keys topped up in USDC on Base or Solana, USDT/USDC on BNB Chain; signed claims for transfers without an order.
Spend controls per key (total cap, daily limit, per-request max), usage audit log, public stats and status page.
Daily catalog and price sync; models sold at list price, never more than 2% above.
