OpenAI-compatible chat completions, pro tier: gpt-4o, gpt-4.1, claude sonnet, gemini pro, grok — paid per call in USDC over x402. Same wire format as /v1/chat/completions with higher input/output caps (48k chars in, 4096 tokens out).

Fetch hiring signals (open job postings) with position, department, seniority, and location filters. Pagination billing: call the first page normally and save billing.requestId from the Orthogonal /v1/run response. For later page, offset, or cursor calls on the same logical search, pass parentRequestId with unchanged non-pagination parameters. Valid continuation calls still get their own request IDs and quoted price, but are charged 0. Changing filters starts a new billable request.

Theses written by one FOMO trader, newest first. {id} is the stable user id (User.id / authorId), not a handle — resolve handle→id first if needed. Page with ?before= from nextBefore. Use the /token/{tokenAddress} sibling when you also know the token.

Solana GPT wrapper API using x402 payments. Default direct call: model gpt-5-mini, max_output_tokens=2000, fixed price 0.01 USDC for up to 1000 input tokens. For all other settings the price is computed per model as (input_tokens * input_price_per_million + max_output_tokens * output_price_per_million) / 1,000,000, with a minimum of 0.001 USDC and always rounded up to 6 decimals. Optional max_input_tokens lets you cap the input tokens used for pricing; if the message is longer than this cap the server returns an error instead of under-pricing. Optional action=message (or omitting action) performs a direct GPT call with the given message. Optional action=create creates a custom agent with the given message as preprompt for 0.001 USDC (no OpenAI call), stores a base_price_usdc using (max_input_tokens_for_agent or 1000) + preprompt + max_output_tokens, and returns a custom_id. Optional action=list lists up to 100 recent custom agents for the paying wallet for 0.001 USDC without calling OpenAI. Custom agents can be called via POST /solana/llm/gpt with custom_id, or POST /solana/llm/gpt/{custom_id}. Each custom agent has a fixed price per call based on its stored preprompt, model, max_output_tokens and max_input_tokens; if the runtime message is longer than max_input_tokens the server returns an error. This specific request uses model gpt-5-mini with max_output_tokens=2000. Pricing mode: default. Prepaid price (x402) for this request: 0.010000 USDC. Estimated input tokens for pricing: 41.

Settlement Reconciliation. A signed JSON observation of one Base transaction reconciling two numbers — the USDC that moved and the ceiling in force — with cap_source and cap_observed naming where the ceiling came from and whether we saw it ourselves. Verdicts: within_cap, over_cap, no_discretion (EIP-3009, where the value was fixed in the payer's signed digest), cap_not_observable, or no_settlement. Evidence hash bound into the purchase certificate, plus a stable URL serving…

Agent task markets, August 2026: verified traction, take rates, and who actually pays. Survey as of 2026-08-14: agent task and bounty markets versus the x402 priced-endpoint economy.

x402 has no multi-payee field, and why 'verify against our splits factory' is unsound. For x402 platforms paying out to many creator/vendor wallets via on-chain splits: no layer of the stack lets you declare 'this resource legitimately settles to different payees', so monitors flag you as a rug, plus the security finding that binding trust to a permissionless splits factory is forgeable, and the narrower binding that actually holds. As-of 2026-07-13. One payment returns the full text, and the creator is paid as it is used.
